　図１は、本実施形態に係るプラントの全体構成を示す概略図である。まず、図１を用いて、本実施形態が対象とするプラント１の構成について説明する。プラント１は、例えば、循環流動層ボイラ（Ｃｉｒｃｕｌａｔｉｎｇ　Ｆｌｕｉｄｉｚｅｄ　Ｂｅｄ型）を含む発電プラント（焼却プラント）であって、高温で流動する珪砂等の循環材を循環させながら燃料を燃焼して、蒸気を発生させるボイラを備えるものである。プラント１の燃料としては、石炭のような化石燃料の他、例えば非化石燃料（木質バイオマス、廃タイヤ、廃プラスチック、スラッジ等）を使用することができる。プラント１で発生した蒸気は、タービン１００の駆動に用いられる。なお、本実施形態が対象とするプラントは、ボイラを含む発電プラントや焼却プラントに限られるものではなく、化学プラント、排水処理プラント等、プロセスデータが取得できるプラントであればよい。 FIG. 1 is a schematic diagram showing the overall configuration of the plant according to the present embodiment. First, the configuration of the plant 1 targeted by the present embodiment will be described with reference to FIG. Plant 1 is, for example, a power generation plant (incinerator plant) including a circulating fluidized bed boiler (Circulating Fluidized Bed type), and burns fuel while circulating a circulating material such as silica sand that flows at a high temperature to generate steam. It is equipped with a boiler to make it. As the fuel of the plant 1, in addition to fossil fuels such as coal, for example, non-fossil fuels (woody biomass, waste tires, waste plastics, sludge, etc.) can be used. The steam generated in the plant 1 is used to drive the turbine 100. The plant targeted by this embodiment is not limited to a power generation plant including a boiler or an incinerator plant, but may be a plant such as a chemical plant or a wastewater treatment plant from which process data can be acquired.
　プラント１は、火炉２内で燃料を燃焼させ、固気分離装置として機能するサイクロン３によって排ガスから循環材を分離し、分離された循環材を火炉２内に戻して循環させるように構成されている。分離された循環材は、サイクロン３の下方に接続された循環材回収管４を経由して火炉２の下部に返送される。なお、循環材回収管４の下部と火炉２の下部とは、流路が絞られたループシール部４ａを介して接続されている。これにより、循環材回収管４の下部には所定量の循環材が貯められた状態となる。サイクロン３によって循環材が取り除かれた排ガスは、排ガス流路３ａを経由して後部煙道５に供給される。 The plant 1 is configured to burn fuel in the furnace 2, separate the circulating material from the exhaust gas by a cyclone 3 functioning as a solid air separating device, and return the separated circulating material to the furnace 2 for circulation. There is. The separated circulating material is returned to the lower part of the furnace 2 via the circulating material recovery pipe 4 connected below the cyclone 3. The lower part of the circulation material recovery pipe 4 and the lower part of the furnace 2 are connected to each other via a loop seal portion 4a having a narrowed flow path. As a result, a predetermined amount of circulating material is stored in the lower part of the circulating material recovery pipe 4. The exhaust gas from which the circulating material has been removed by the cyclone 3 is supplied to the rear flue 5 via the exhaust gas flow path 3a.
　ボイラは、燃料を燃焼させるための火炉２と、燃焼により得られた熱を用いて水蒸気等を発生させるための熱交換器を備える。火炉２の中間部には、燃料を供給する燃料供給口２ａが設けられており、火炉２の上部には、燃焼ガスを排出するガス出口２ｂが設けられている。図示されていない燃料供給装置から火炉２に供給される燃料は、燃料供給口２ａを介して火炉２の内部に供給される。また、火炉２の炉壁には、ボイラ給水を加熱するための炉壁管６が設けられている。炉壁管６を流れるボイラ給水は、火炉２での燃焼によって加熱される。 The boiler is equipped with a furnace 2 for burning fuel and a heat exchanger for generating steam or the like using the heat obtained by the combustion. A fuel supply port 2a for supplying fuel is provided in the middle portion of the furnace 2, and a gas outlet 2b for discharging combustion gas is provided in the upper portion of the furnace 2. The fuel supplied to the furnace 2 from the fuel supply device (not shown) is supplied to the inside of the furnace 2 through the fuel supply port 2a. Further, a furnace wall pipe 6 for heating the boiler water supply is provided on the furnace wall of the furnace 2. The boiler water supply flowing through the furnace wall pipe 6 is heated by combustion in the furnace 2.
　火炉２内では、下部の給気ライン２ｃから導入される燃焼・流動用の空気により、燃料供給口２ａから供給された燃料を含む固形物が流動し、燃料は流動しながら例えば約８００～９００℃で燃焼する。サイクロン３には、火炉２で発生した燃焼ガスが循環材を同伴しながら導入される。サイクロン３は、遠心分離作用により循環材と気体とを分離し、循環材回収管４を介して分離された循環材を火炉２に戻すとともに、循環材が除かれた燃焼ガスを排ガス流路３ａから後部煙道５へと送出する。 In the furnace 2, the air for combustion and flow introduced from the lower air supply line 2c causes solid matter including fuel supplied from the fuel supply port 2a to flow, and the fuel flows while flowing, for example, about 800 to 900. Burn at ° C. The combustion gas generated in the furnace 2 is introduced into the cyclone 3 with a circulating material. The cyclone 3 separates the circulating lumber and the gas by the centrifugal separation action, returns the circulating lumber separated through the circulating lumber recovery pipe 4 to the furnace 2, and returns the combustion gas from which the circulating lumber is removed to the exhaust gas flow path 3a. To the rear flue 5.
　火炉２では、底部に炉内ベッド材と呼ばれる循環材の一部が滞留する。このベッド材には、循環流動に不適な粗い粒径を有するベッド材や排燃夾雑物が含まれることがあり、これらの循環材として不適なベッド材によって流動不良が発生することがある。そのため、流動不良を抑制するために、火炉２では、底部の排出口２ｄから炉内ベッド材が連続的又は断続的に外部に排出されている。排出されたベッド材は、図示されていない循環ライン上で金属や粗大粒径等の不適物を取り除いた後、再び火炉２に供給されるか、若しくはそのまま廃棄される。火炉２の循環材は、火炉２、サイクロン３及び循環材回収管４で構成される循環系内を循環する。 In the furnace 2, a part of the circulating material called the in-furnace bed material stays at the bottom. This bed material may contain a bed material having a coarse particle size unsuitable for circulating flow and exhaust combustion contaminants, and the bed material unsuitable for these circulating materials may cause flow failure. Therefore, in order to suppress flow failure, in the furnace 2, the bed material in the furnace is continuously or intermittently discharged to the outside from the discharge port 2d at the bottom. The discharged bed material is supplied to the furnace 2 again after removing unsuitable substances such as metal and coarse particle size on a circulation line (not shown), or is discarded as it is. The circulatory material of the circulatory furnace 2 circulates in the circulatory system including the furnace 2, the cyclone 3, and the circulatory material recovery pipe 4.
　後部煙道５は、サイクロン３から排出されたガスを後段へ流す流路を有している。後部煙道５は、排ガスの熱を回収する排熱回収部として、過熱蒸気を発生させる過熱器１０と、ボイラ給水を予熱する節炭器１２と、を有している。後部煙道５を流れる排ガスは、過熱器１０及び節炭器１２を流通する蒸気やボイラ給水と熱交換されて冷却される。また、節炭器１２を通過したボイラ給水が貯留される蒸気ドラム８を有し、蒸気ドラム８は炉壁管６にも接続されている。 The rear flue 5 has a flow path for flowing the gas discharged from the cyclone 3 to the rear stage. The rear flue 5 has a superheater 10 for generating superheated steam and an economizer 12 for preheating the boiler water supply as an exhaust heat recovery unit for recovering the heat of the exhaust gas. The exhaust gas flowing through the rear flue 5 is heat-exchanged with the steam flowing through the superheater 10 and the economizer 12 and the boiler supply water to be cooled. Further, it has a steam drum 8 in which boiler water supply that has passed through the economizer 12 is stored, and the steam drum 8 is also connected to a furnace wall pipe 6.
　節炭器１２は、排ガスの熱をボイラ給水に伝熱して、ボイラ給水を予熱するものである。節炭器１２は、管２１によってポンプ７と接続される一方、管２２によって蒸気ドラム８と接続されている。ポンプ７から管２１を経由して節炭器１２に供給され、節炭器１２によって予熱されたボイラ給水は、管２２を経由して蒸気ドラム８に供給される。 The economizer 12 transfers the heat of the exhaust gas to the boiler water supply to preheat the boiler water supply. The economizer 12 is connected to the pump 7 by a pipe 21 while being connected to the steam drum 8 by a pipe 22. The boiler water supplied from the pump 7 to the economizer 12 via the pipe 21 and preheated by the economizer 12 is supplied to the steam drum 8 via the pipe 22.
　蒸気ドラム８には、降水管８ａ及び炉壁管６が接続されている。蒸気ドラム８内のボイラ給水は、降水管８ａを下降し、火炉２の下部側で炉壁管６に導入されて蒸気ドラム８へ向かって流通する。炉壁管６内のボイラ給水は、火炉２内で発生する燃焼熱によって加熱されて、蒸気ドラム８内で蒸発し蒸気となる。 A precipitation pipe 8a and a furnace wall pipe 6 are connected to the steam drum 8. The boiler water supply in the steam drum 8 descends from the precipitation pipe 8a, is introduced into the furnace wall pipe 6 on the lower side of the furnace 2, and flows toward the steam drum 8. The boiler water supply in the furnace wall pipe 6 is heated by the combustion heat generated in the furnace 2 and evaporates in the steam drum 8 to become steam.
　蒸気ドラム８には、内部の蒸気を排出する飽和蒸気管８ｂが接続されている。飽和蒸気管８ｂは、蒸気ドラム８と過熱器１０とを接続している。蒸気ドラム８内の蒸気は、飽和蒸気管８ｂを経由して過熱器１０に供給される。過熱器１０は、排ガスの熱を用いて蒸気を過熱して過熱蒸気を生成するものである。過熱蒸気は、管１０ａを通り、プラント１外のタービン１００に供給されて発電に利用される。 A saturated steam pipe 8b for discharging internal steam is connected to the steam drum 8. The saturated steam pipe 8b connects the steam drum 8 and the superheater 10. The steam in the steam drum 8 is supplied to the superheater 10 via the saturated steam pipe 8b. The superheater 10 uses the heat of the exhaust gas to superheat the steam to generate superheated steam. The superheated steam passes through the pipe 10a, is supplied to the turbine 100 outside the plant 1, and is used for power generation.
　タービン１００から排出された蒸気の圧力と温度は、過熱器１０から排出される蒸気の圧力と温度よりも低い。特に限定されるものではないが、タービン１００へ供給される蒸気の圧力は、約１０～１７ＭＰａ程度であり、温度は約５３０～５７０℃程度となる。タービン１００から排出される蒸気の圧力は、約３～５ＭＰａ程度であり、温度は約３５０～４００℃程度となる。 The pressure and temperature of the steam discharged from the turbine 100 is lower than the pressure and temperature of the steam discharged from the superheater 10. Although not particularly limited, the pressure of the steam supplied to the turbine 100 is about 10 to 17 MPa, and the temperature is about 530 to 570 ° C. The pressure of the steam discharged from the turbine 100 is about 3 to 5 MPa, and the temperature is about 350 to 400 ° C.
　タービン１００の下流には復水器１０２が設けられている。タービン１００から排出された蒸気は復水器１０２に供給され、復水器１０２において凝縮して飽和水に戻された上でポンプ７へと供給される。タービン１００には、タービン１００の回転により得られる運動エネルギーを電気エネルギーに変換するジェネレータが接続される。 A condenser 102 is provided downstream of the turbine 100. The steam discharged from the turbine 100 is supplied to the condenser 102, condensed in the condenser 102 and returned to saturated water, and then supplied to the pump 7. A generator that converts the kinetic energy obtained by the rotation of the turbine 100 into electrical energy is connected to the turbine 100.
　ポンプ７ａは、復水器１０２の水位を一定に保つように、補給水を供給する。図１では、ポンプ７ａにより補給される補給水流量ｕ１（「プロセスデータ」の一例）を示している。 The pump 7a supplies make-up water so as to keep the water level of the condenser 102 constant. FIG. 1 shows a make-up water flow rate u1 (an example of “process data”) replenished by the pump 7a.
　本実施形態で取り扱うプロセスデータ（プラント１の運転に関するデータ）は、プラント１に関する任意のデータであってよいが、例えば、プラント１の状態をセンサで測定したデータ（「プロセスデータ」の一例）であってよく、より具体的には、プラント１の温度、圧力及び流量等の測定値を含んでよい。図１では、ポンプ７から節炭器１２に供給されるボイラ給水流量ｕ２（「プロセスデータ」の一例）を示している。さらに、図１では、過熱器１０からタービン１００に供給されるボイラ出口蒸気流量ｕ３（「プロセスデータ」の一例）を示し、蒸気ドラム８から過熱器１０に供給される飽和蒸気流量ｕ４を示している。なお、補給水流量ｕ１は、飽和蒸気流量ｕ４に追従するように制御されてよい。また、ボイラ出口蒸気流量ｕ３（又は過熱蒸気流量）と、蒸気ドラム８の液面レベルの双方を監視しながら、ボイラ給水流量ｕ２を調整に追従するように制御されてよい。 The process data (data related to the operation of the plant 1) handled in the present embodiment may be arbitrary data related to the plant 1, but for example, data obtained by measuring the state of the plant 1 with a sensor (an example of “process data”). It may be possible, and more specifically, it may include measured values such as temperature, pressure and flow rate of the plant 1. FIG. 1 shows a boiler supply water flow rate u2 (an example of “process data”) supplied from the pump 7 to the economizer 12. Further, FIG. 1 shows a boiler outlet steam flow rate u3 (an example of “process data”) supplied from the superheater 10 to the turbine 100, and shows a saturated steam flow rate u4 supplied from the steam drum 8 to the superheater 10. There is. The make-up water flow rate u1 may be controlled to follow the saturated steam flow rate u4. Further, the boiler supply water flow rate u2 may be controlled to follow the adjustment while monitoring both the boiler outlet steam flow rate u3 (or superheated steam flow rate) and the liquid level of the steam drum 8.
　プラント１を構成する管系統に破孔が生じた場合、補給水流量ｕ１が上昇したり、ボイラ給水流量ｕ２とボイラ出口蒸気流量ｕ３の流量差が増大したりする。ＤＣＳ（Ｄｉｓｔｒｉｂｕｔｅｄ　Ｃｏｎｔｒｏｌ　Ｓｙｓｔｅｍ）２０は、補給水流量ｕ１、ボイラ給水流量ｕ２、ボイラ出口蒸気流量ｕ３及び飽和蒸気流量ｕ４等のプラント１のプロセスデータをプラント１から受信し、プラント１を構成するボイラおよびタービン１００の稼働率を含む稼働状況を把握し、プラント１に異常が生じていないか監視する。 When a hole occurs in the pipe system constituting the plant 1, the make-up water flow rate u1 increases, or the flow rate difference between the boiler supply water flow rate u2 and the boiler outlet steam flow rate u3 increases. The DCS (Distributed Control System) 20 receives the process data of the plant 1 such as the make-up water flow rate u1, the boiler supply water flow rate u2, the boiler outlet steam flow rate u3, and the saturated steam flow rate u4 from the plant 1, and the boiler and the boiler constituting the plant 1 The operating status including the operating rate of the turbine 100 is grasped, and whether or not an abnormality has occurred in the plant 1 is monitored.

　次に、図２及び図３を用いて、本実施形態に係るシステム３０について説明する。図２は、本実施形態に係るシステム３０の機能ブロックを示す図である。図３は、本実施形態に係るシステム３０の物理的構成を示す図である。 Next, the system 30 according to the present embodiment will be described with reference to FIGS. 2 and 3. FIG. 2 is a diagram showing a functional block of the system 30 according to the present embodiment. FIG. 3 is a diagram showing a physical configuration of the system 30 according to the present embodiment.
　ＤＣＳ２０は、プラント１を制御するための分散制御システムであり、図２に示されるように、プラント１に設けられるセンサ等からプロセスデータを取得し、これに基づいてプラント１を制御するための制御信号をプラント１に供給する。 The DCS 20 is a distributed control system for controlling the plant 1, and as shown in FIG. 2, control for acquiring process data from a sensor or the like provided in the plant 1 and controlling the plant 1 based on the process data. The signal is supplied to the plant 1.
　システム３０は、制御部３１、及び表示装置３２、を備えている。制御部３１は、例えば、プロセスデータ取得部３１１と、指標算出部３１２と、受付部３１３と、表示制御部３１４とを備える。 The system 30 includes a control unit 31 and a display device 32. The control unit 31 includes, for example, a process data acquisition unit 311, an index calculation unit 312, a reception unit 313, and a display control unit 314.
　プロセスデータ取得部３１１は、例えば、ＤＣＳ２０からプロセスデータを取得する。プロセスデータ取得部３１１は、プラント１の運転中にＤＣＳ２０からプロセスデータを順次に取得する。 The process data acquisition unit 311 acquires process data from, for example, DCS20. The process data acquisition unit 311 sequentially acquires process data from the DCS 20 during the operation of the plant 1.
　指標算出部３１２は、プロセスデータに基づいて、プラント１の運転に関する各種の指標を算出する。指標算出部３１２が算出する指標は、プラント１の運転に関するものであれば任意の指標であってよいが、例えば、プラント１の運転に関する稼働率、及びプラント１の運転に関する効率を含んでもよい。 The index calculation unit 312 calculates various indexes related to the operation of the plant 1 based on the process data. The index calculated by the index calculation unit 312 may be any index as long as it relates to the operation of the plant 1, but may include, for example, the operating rate related to the operation of the plant 1 and the efficiency related to the operation of the plant 1.
　指標算出部３１２は、例えば、予め設定された任意のタイミング（日毎、週毎、月毎等）において、プラント１の運転に関する稼働率を算出する。ここで、プラント１の運転に関する稼働率は、プラント１全体の稼働率の他、プラント１に含まれる各種のコンポーネントの稼働率を含んでもよい。具体的には、例えば、プラント１の運転に関する稼働率は、プラント１に含まれるボイラの稼働率であるボイラ稼働率、プラント１に含まれるタービンの稼働率であるタービン稼働率、及びプラント１全体の稼働率であるプラント稼働率を含んでもよい。 The index calculation unit 312 calculates, for example, the operating rate related to the operation of the plant 1 at an arbitrary timing (daily, weekly, monthly, etc.) set in advance. Here, the operating rate related to the operation of the plant 1 may include the operating rate of various components included in the plant 1 in addition to the operating rate of the entire plant 1. Specifically, for example, the operating rate related to the operation of the plant 1 is the boiler operating rate which is the operating rate of the boiler included in the plant 1, the turbine operating rate which is the operating rate of the turbine included in the plant 1, and the entire plant 1. It may include the plant operating rate, which is the operating rate of.
　プラント１の運転に関する稼働率は、例えば、プラント１の少なくとも一部のコンポーネントが稼働している時間の合計を、稼働率算出期間で除して得られる値として算出されてもよい。なお、「対象となるコンポーネントが稼働している時間の合計」は、当該対象となるコンポーネントの任意の効率に基づいて算出されてもよい。具体的には、任意の周期で区切られた単位時間に、当該単位時間における当該コンポーネントの運転効率（例えば、ボイラであれば負荷効率）を乗じて得られる値を、稼働率算出期間について合計（積算、積分等）して得られる値であってもよい。また、指標算出部３１２は、例えば後述する稼働率表示画面ＤＰ１において選択された集計周期によって、稼働率を算出してもよい。 The operating rate related to the operation of the plant 1 may be calculated, for example, as a value obtained by dividing the total operating time of at least a part of the components of the plant 1 by the operating rate calculation period. The "total time during which the target component is operating" may be calculated based on any efficiency of the target component. Specifically, the value obtained by multiplying the unit time divided by an arbitrary cycle by the operating efficiency of the component in the unit time (for example, the load efficiency in the case of a boiler) is totaled for the operating rate calculation period (for example, the operating rate calculation period). It may be a value obtained by integration, integration, etc.). Further, the index calculation unit 312 may calculate the operation rate by, for example, the aggregation cycle selected on the operation rate display screen DP1 described later.
　また、指標算出部３１２は、稼働率の算出において、稼働率算出期間から操作者が登録した計画停止期間を除いてもよい。ここで、計画停止期間は、プラント１の運転を停止することが計画された期間であり、例えば、プラント１の定期点検や中間点検等の点検のためにプラント１の稼働を停止する期間がこれに含まれ得る。したがって、指標算出部３１２は、計画停止期間を除いた稼働率と、計画停止期間を含めた稼働率との両方を算出可能である。なお、計画停止期間を除いた稼働率は、稼働率算出期間から計画停止期間が除かれた期間である計画運転期間（プラント１の運転が計画されていた期間）と、プラント１の運転が行われていた運転期間とに基づいて算出される。具体的には、計画停止期間を除いた稼働率は、当該計画運転期間に対する当該運転期間の割合として算出される。このように、計画停止期間を除いた稼働率は、プラント１の運転が計画されていた期間における正味の稼働率を表しているといえる。 Further, the index calculation unit 312 may exclude the planned suspension period registered by the operator from the operation rate calculation period in the calculation of the operation rate. Here, the planned outage period is a period in which the operation of the plant 1 is planned to be stopped. For example, this is a period in which the operation of the plant 1 is stopped for inspections such as periodic inspections and intermediate inspections of the plant 1. Can be included in. Therefore, the index calculation unit 312 can calculate both the operating rate excluding the planned outage period and the operating rate including the planned outage period. The operating rate excluding the planned outage period is the planned operation period (the period in which the operation of the plant 1 was planned), which is the period in which the planned outage period is excluded from the operation rate calculation period, and the operation of the plant 1. It is calculated based on the operating period that was being used. Specifically, the operating rate excluding the planned outage period is calculated as the ratio of the operating period to the planned operating period. As described above, the operating rate excluding the planned outage period can be said to represent the net operating rate during the planned operation period of the plant 1.
　また、プラント１の運転に関する効率は、例えば、プラント１の少なくとも一部のコンポーネントの任意の効率であってよい。プラント１の運転に関する効率は、例えば、プラント１に含まれるボイラの効率であるボイラ効率ηｂ、プラント１に含まれるタービンの効率であるタービン室効率ηｔ、及びプラント１全体の効率である発電端効率ηｎを含んでもよい。 Further, the efficiency regarding the operation of the plant 1 may be, for example, any efficiency of at least a part of the components of the plant 1. The efficiency related to the operation of the plant 1 is, for example, the boiler efficiency η b which is the efficiency of the boiler included in the plant 1, the turbine chamber efficiency η t which is the efficiency of the turbine included in the plant 1, and the power generation which is the efficiency of the entire plant 1. The edge efficiency η n may be included.
　ボイラ効率ηｂ（％）は、ηｂ＝（１－Ｌ／（Ｈ＋Ｑ））×１００として定義されてもよい。ここで、Ｌは、熱損失量の合計（ｋＪ／ｋｇ）であり、Ｈは燃料の発熱量（ｋＪ／ｋｇ〕であり、Ｑは燃料以外の入熱量の合計（ｋＪ／ｋｇ）である。 Boiler efficiency η b (%) may be defined as η b = (1-L / (H + Q)) × 100. Here, L is the total amount of heat loss (kJ / kg), H is the calorific value of the fuel (kJ / kg), and Q is the total amount of heat input other than the fuel (kJ / kg).
　タービン室効率ηｔ（％）は、ηｔ＝Ｐｇ×３．６／｛Ｚ×（ｈｓ－ｈｗ）｝×１００として定義されてもよい。ここで、Ｐｇは発電出力（ｋＷ）であり、Ｚは水・蒸気流量（ｋｇ／ｈ）であり、ｈｓは蒸気エンタルピ（ｋｇ／ｈ〕であり、ｈｗは給水エンタルピ（ｋｇ／ｈ）である。 Turbine chamber efficiency η t (%) may be defined as η t = P g × 3.6 / {Z × (h s −h w )} × 100. Here, P g is the power generation output (kW), Z is the water / steam flow rate (kg / h), h s is the steam enthalpy (kg / h), and h w is the water supply enthalpy (kg / h). ).
　発電端効率ηｎ（％）は、ηｎ＝ηｂ×ηＰ／１００×ηｔ／１００として定義されてもよい。ここで、ηＰは、主管伝達効率（％）である。 The power generation end efficiency η n (%) may be defined as η n = η b × η P / 100 × η t / 100. Here, η P is the main transmission efficiency (%).
　受付部３１３は、操作者の操作に応じた各種の情報の入力、指示、及び選択等を受け付ける。受付部３１３は、例えば、表示画面遷移の指示、計画停止期間の指定、入力、選択、稼働率算出期間や集計周期の選択、プラント１の運転に関する指標の表示の選択等を受け付ける。 The reception unit 313 accepts input, instruction, selection, etc. of various information according to the operation of the operator. The reception unit 313 receives, for example, an instruction of a display screen transition, a designation of a planned stop period, an input, a selection, a selection of an operating rate calculation period and an aggregation cycle, a selection of an index display related to the operation of the plant 1, and the like.

Display on 32.
　表示装置３２は、表示制御部３１４によって供給される表示データに基づいて、プラント１の運転に関する情報を含む各種の表示画面を表示する。表示装置３２が表示する各種の表示画面については後述する。 The display device 32 displays various display screens including information on the operation of the plant 1 based on the display data supplied by the display control unit 314.

　ダッシュボード表示画面ＤＰ２は、プラント１の運転に関する各種の指標をリアルタイムに表示する。換言すれば、ダッシュボード表示画面ＤＰ２は、所定時間毎に、プラント１の運転に関する最新の各種の指標を表示する。ダッシュボード表示画面ＤＰ２は、例えば、プラント１の運転に関する各種の指標に基づくトレンドグラフ等を表示する。また、ダッシュボード表示画面ＤＰ２は、例えば、プラント１の停止可能性を有する異常の発生や可能性を示す異常表示と、プラント１に関するプロセスデータが所定の状態となった場合の警告の発生や可能性を示す警告表示とを表示する。また、ダッシュボード表示画面ＤＰ２は、例えば、アラームの件数や発生時刻を表示する。 The dashboard display screen DP2 displays various indicators related to the operation of plant 1 in real time. In other words, the dashboard display screen DP2 displays various latest indicators regarding the operation of the plant 1 at predetermined time intervals. The dashboard display screen DP2 displays, for example, a trend graph or the like based on various indicators related to the operation of the plant 1. Further, on the dashboard display screen DP2, for example, an abnormality display indicating the occurrence or possibility of an abnormality having the possibility of stopping the plant 1 and a warning when the process data related to the plant 1 is in a predetermined state can be generated. A warning display indicating the sex is displayed. Further, the dashboard display screen DP2 displays, for example, the number of alarms and the time of occurrence.
　次に、図５を用いて、稼働率表示画面ＤＰ１の一例を説明する。稼働率表示画面ＤＰ１は、領域Ｒ１０～Ｒ１６と、算出表示５０とを含む。 Next, an example of the operating rate display screen DP1 will be described with reference to FIG. The operating rate display screen DP1 includes areas R10 to R16 and a calculation display 50.
　領域Ｒ１０は、例えば、稼働率表示画面ＤＰ１の上部に表示される。領域Ｒ１０には、現在の画面のステータスとして、「稼働率計算」と表示されている。領域Ｒ１０の表示により、現在の画面が、いずれのシステムにおけるいずれのステータスであるかを容易に把握することができる。 The area R10 is displayed at the upper part of the operating rate display screen DP1, for example. In the area R10, "operation rate calculation" is displayed as the status of the current screen. By displaying the area R10, it is possible to easily grasp which status in which system the current screen is.
　領域Ｒ１１は、例えば、稼働率表示画面ＤＰ１の左上に表示される。領域Ｒ１１は、稼働率を算出乃至表示する期間（稼働率算出期間）の入力を受け付ける。図５に示す例では、稼働率算出期間の開始時点と、終了時点とがそれぞれ入力可能となっている。図５に示す例では、開始時点及び終了時点はいずれも年月によって指定する形式であるが、これに限らず更に日にちや時刻によって指定する形式としてもよい。また、領域Ｒ１１は、稼働率算出期間の終了時点として選択可能な時点の表示を含む。図５に示す例では、稼働率算出期間の終了時点として選択可能な時点として、領域Ｒ１１に「算出可能月：～２０２０－０５」と表示されている。これは、２０２０年５月までの稼働率が算出乃至表示可能であることを示している。これにより、操作者は、当該表示に示された時点までの時点を稼働率算出期間の開始時点や終了時点として入力可能となる。 The area R11 is displayed on the upper left of the operating rate display screen DP1, for example. The area R11 accepts an input of a period for calculating or displaying the operating rate (operating rate calculation period). In the example shown in FIG. 5, the start time point and the end time point of the operation rate calculation period can be input respectively. In the example shown in FIG. 5, both the start time point and the end time point are specified by the year and month, but the format is not limited to this and may be further specified by the date and time. Further, the area R11 includes a display of a time point that can be selected as the end time point of the operating rate calculation period. In the example shown in FIG. 5, "calculable month: ~ 2020-05" is displayed in the area R11 as a time point that can be selected as the end time point of the operation rate calculation period. This indicates that the operating rate up to May 2020 can be calculated and displayed. As a result, the operator can input the time points up to the time point indicated on the display as the start time point and the end time point of the operation rate calculation period.
　領域Ｒ１２は、例えば、稼働率表示画面ＤＰ１の領域Ｒ１１の下側に表示される。領域Ｒ１２は、集計周期の入力を受け付ける。ここで、集計周期は、一つの稼働率を算出するために集計する期間を区切るための周期である。換言すれば、当該集計周期に示された期間を一つの単位とする稼働率が算出乃至表示される。集計周期の長さは、特に限定されないが、図５に示す例では、集計周期を月とする「ＭＯＮＴＨ」と、集計周期を年とする年とする「ＹＥＡＲ」とが含まれる。 The area R12 is displayed, for example, below the area R11 of the operation rate display screen DP1. The area R12 accepts the input of the aggregation cycle. Here, the aggregation cycle is a cycle for dividing the aggregation period for calculating one operating rate. In other words, the operating rate with the period indicated in the aggregation cycle as one unit is calculated or displayed. The length of the aggregation cycle is not particularly limited, but in the example shown in FIG. 5, "MONTH" whose aggregation cycle is a month and "YEAR" whose aggregation cycle is a year are included.
　領域Ｒ１３は、例えば、稼働率表示画面ＤＰ１の領域Ｒ１２の下側に表示される。領域Ｒ１３は、計画停止期間に関する各種の表示を含む。領域Ｒ１３は、既に登録済みの計画停止期間を表示してもよい。領域Ｒ１３は、最新データ更新表示５１と、計画停止追加表示５２と、削除表示５３と、を含む。 The area R13 is displayed, for example, below the area R12 of the operation rate display screen DP1. Region R13 includes various indications for the planned outage period. Area R13 may display a planned outage period that has already been registered. The area R13 includes the latest data update display 51, the planned stop addition display 52, and the deletion display 53.
　最新データ更新表示５１が選択されると、領域Ｒ１３において、最新の計画停止期間を反映した処理が実行される。例えば、領域Ｒ１３において、登録済みの最新の計画停止期間が表示されてもよい。これにより操作者は、計画停止期間として登録されている期間を把握することができる。また、例えば、指標算出部３１２は、最新の計画停止期間を反映した稼働率を算出し、算出した稼働率をＲＯＭ３０ｃ等の記憶部に記憶させてよい。 When the latest data update display 51 is selected, a process reflecting the latest planned outage period is executed in the area R13. For example, in region R13, the latest registered outage period may be displayed. As a result, the operator can grasp the period registered as the planned suspension period. Further, for example, the index calculation unit 312 may calculate an operation rate reflecting the latest planned outage period and store the calculated operation rate in a storage unit such as ROM 30c.
　計画停止追加表示５２が選択されると、例えば図６に示す計画停止期間を追加するための領域Ｒ１３１が表示される。図６に示すとおり、領域Ｒ１３１は稼働率表示画面ＤＰ１においてポップアップの態様で表示される。図６に示す例では、計画停止期間の開始時点と、終了時点とがそれぞれ入力可能となっている。領域Ｒ１３１に含まれる「追加」の表示を選択すると、入力された期間が新たに計画停止期間として追加される。「閉じる」の表示を選択すると、計画停止期間の追加の操作が中断され、領域Ｒ１３１の表示が消える。 When the planned stop addition display 52 is selected, for example, the area R131 for adding the planned stop period shown in FIG. 6 is displayed. As shown in FIG. 6, the area R131 is displayed in a pop-up manner on the operating rate display screen DP1. In the example shown in FIG. 6, the start time point and the end time point of the planned stop period can be input respectively. When the display of "addition" included in the area R131 is selected, the input period is newly added as the planned suspension period. When the display of "close" is selected, the additional operation of the planned stop period is interrupted, and the display of the area R131 disappears.
　図５を再び参照する。削除表示５３が選択されると、例えば登録された計画停止期間のうちから選択された任意の計画停止期間について、当該登録が削除される。操作者は、例えば、最新データ更新表示５１が選択されることにより表示された登録済みの計画停止期間のうちから、削除したい期間を選択した上で削除表示５３を選択することにより、当該選択した期間について計画停止期間の登録を削除することができる。 Refer to FIG. 5 again. When the deletion display 53 is selected, for example, the registration is deleted for any planned suspension period selected from the registered planned suspension periods. For example, the operator selects the period to be deleted from the registered planned suspension periods displayed by selecting the latest data update display 51, and then selects the deletion display 53. You can delete the registration of the planned outage period for the period.
　算出表示５０を選択すると、例えば稼働率表示画面ＤＰ１の領域Ｒ１０～１３よりも右側において、プラント１の運転に関する稼働率が表示される。図５に示す例では、３つの領域Ｒ１４～１６のそれぞれにおいて、稼働率算出期間である２０２０年２月、３月、及び４月の各種の稼働率が棒グラフの態様で表示されている。例えば、領域Ｒ１４にはボイラ稼働率が、領域Ｒ１５及びＲ１６にはプラント稼働率がそれぞれ表示されている。なお、領域Ｒ１５には計画停止期間を含む稼働率が表示され、領域Ｒ１６には計画停止期間を除いた稼働率（計画運転期間に対する当該運転期間の割合としての稼働率）が表示されている。各棒グラフのうち上側に設けられた斜線部は対象となるコンポーネントが稼働していなかった期間の割合を示している。稼働率表示画面ＤＰ１に含まれる稼働率の表示領域の数は特に限定されず、図５に示すように３つであってもよいし、１つ、２つ、又は４つ以上であってもよい。また、稼働率の表示態様は、棒グラフに限らず、折れ線グラフ、円グラフ、散布図、ヒストグラム等の任意の態様であってよい。 When the calculation display 50 is selected, for example, the operating rate related to the operation of the plant 1 is displayed on the right side of the areas R10 to 13 of the operating rate display screen DP1. In the example shown in FIG. 5, in each of the three regions R14 to 16, various operating rates in February, March, and April 2020, which are the operating rate calculation periods, are displayed in the form of a bar graph. For example, the boiler operating rate is displayed in the area R14, and the plant operating rate is displayed in the areas R15 and R16, respectively. The operating rate including the planned outage period is displayed in the area R15, and the operating rate excluding the planned outage period (the operating rate as a ratio of the operating period to the planned operating period) is displayed in the area R16. The shaded area on the upper side of each bar graph shows the percentage of the period during which the target component was not in operation. The number of operating rate display areas included in the operating rate display screen DP1 is not particularly limited, and may be three, one, two, or four or more as shown in FIG. good. Further, the display mode of the operating rate is not limited to the bar graph, and may be any mode such as a line graph, a pie chart, a scatter chart, and a histogram.
　稼働率表示画面ＤＰ１においては、計画停止期間を含む稼働率と、計画停止期間を除いた稼働率とが表示されている。更に、稼働率表示画面ＤＰ１においては、これら稼働率が並べて配置されている。そのため、操作者は、計画停止期間が稼働率に与える影響を容易に把握することが可能となる。 On the operating rate display screen DP1, the operating rate including the planned outage period and the operating rate excluding the planned outage period are displayed. Further, on the operating rate display screen DP1, these operating rates are arranged side by side. Therefore, the operator can easily grasp the influence of the planned outage period on the operating rate.
　次に、図７を用いて、本実施形態に係る稼働率の表示に係る動作処理について説明する。図７は、当該動作処理の一例を示すフローチャートである。なお、以下に示すステップの内容や順序は一例であって、当該動作処理がこれに限られるものではない。 Next, the operation process related to the display of the operating rate according to the present embodiment will be described with reference to FIG. 7. FIG. 7 is a flowchart showing an example of the operation process. The contents and order of the steps shown below are examples, and the operation processing is not limited to this.
　まず、プラント１の運転中において、プロセスデータ取得部３１１は、ＤＣＳ２０からプラント１のプロセスデータを取得する（Ｓ１０）。プロセスデータ取得部３１１は、ＤＣＳ２０から順次に供給されるプロセスデータを、ＲＯＭ３０ｃ等に記憶させてもよい。 First, during the operation of the plant 1, the process data acquisition unit 311 acquires the process data of the plant 1 from the DCS 20 (S10). The process data acquisition unit 311 may store the process data sequentially supplied from the DCS 20 in the ROM 30c or the like.
　その後、指標算出部３１２は、予め設定された任意のタイミングにおいて、予め設定された条件による稼働率を算出する（Ｓ１１）。例えば、指標算出部３１２は、月毎に、当該月におけるプラント１の稼働率、及び／又は、プラント１に含まれる各種のコンポーネントの稼働率（ボイラ稼働率、タービン稼働率等）を算出する。このとき、計画停止期間が登録されている場合は、計画停止期間を含む稼働率及び／又は計画停止期間を除いた稼働率を算出してもよい。指標算出部３１２は、算出された稼働率をＲＯＭ３０ｃ等の記憶部に記憶する。 After that, the index calculation unit 312 calculates the operating rate under the preset conditions at any preset timing (S11). For example, the index calculation unit 312 calculates the operating rate of the plant 1 in the month and / or the operating rate of various components included in the plant 1 (boiler operating rate, turbine operating rate, etc.) every month. At this time, if the planned suspension period is registered, the operating rate including the planned suspension period and / or the operating rate excluding the planned suspension period may be calculated. The index calculation unit 312 stores the calculated operating rate in a storage unit such as a ROM 30c.
　受付部３１３は、操作者が計画停止期間の登録の操作を行った場合、当該計画停止期間の登録を受け付ける（Ｓ１２）。具体的には、操作者が、稼働率表示画面ＤＰ１の領域Ｒ１３の計画停止追加表示５２を選択することにより領域Ｒ１３１が表示され、当該領域Ｒ１３１において計画停止期間の登録が行われる。そして、例えば受付部３１３は、計画停止期間をＲＯＭ３０ｃ等の記憶部に記憶させる。このとき、例えば稼働率表示画面ＤＰ２の領域Ｒ１３の最新データ更新表示５１が選択されたこと等に応じて、指標算出部３１２は最新の計画停止期間を反映した稼働率を新たに算出し、これをＲＯＭ３０ｃ等の記憶部に記憶させてもよい。 When the operator performs the operation of registering the planned suspension period, the reception unit 313 accepts the registration of the planned suspension period (S12). Specifically, the operator selects the planned stop addition display 52 of the area R13 of the operation rate display screen DP1, the area R131 is displayed, and the planned stop period is registered in the area R131. Then, for example, the reception unit 313 stores the planned stop period in a storage unit such as the ROM 30c. At this time, for example, in response to the selection of the latest data update display 51 in the area R13 of the operation rate display screen DP2, the index calculation unit 312 newly calculates the operation rate reflecting the latest planned outage period. May be stored in a storage unit such as ROM 30c.
　受付部３１３は、操作者が稼働率表示に関する各種の条件を選択した場合、当該選択を受け付ける（Ｓ１３）。例えば、受付部３１３は、稼働率表示画面ＤＰ２の領域Ｒ１１に対する操作者の操作に応じて、稼働率算出期間の選択を受け付ける。また、受付部３１３は、稼働率表示画面ＤＰ２の領域Ｒ１２に対する操作者の操作に応じて、集計周期の選択を受け付ける。なお、指標算出部３１２は、これら操作に応じて、新たな条件における稼働率を算出し、これをＲＯＭ３０ｃ等の記憶部に記憶させてもよい。 When the operator selects various conditions related to the operation rate display, the reception unit 313 accepts the selection (S13). For example, the reception unit 313 accepts the selection of the operation rate calculation period according to the operation of the operator with respect to the area R11 of the operation rate display screen DP2. Further, the reception unit 313 accepts the selection of the aggregation cycle according to the operation of the operator with respect to the area R12 of the operation rate display screen DP2. The index calculation unit 312 may calculate the operating rate under new conditions according to these operations and store it in a storage unit such as the ROM 30c.
　表示制御部３１４は、操作者が稼働率表示画面ＤＰ２の算出表示５０を選択した場合、選択された各種の条件（稼働率算出期間、集計期間等）における稼働率を稼働率表示画面ＤＰ２に表示させる（Ｓ１４）。例えば、表示制御部３１４は、図５に示した領域Ｒ１４～Ｒ１６等を稼働率表示画面ＤＰ２に表示させる。なお、選択された各種の条件（稼働率算出期間、集計期間等）における稼働率がＲＯＭ３０ｃ等の記憶部に記憶されていない場合、指標算出部３１２は、新たに当該条件における稼働率を算出し、これをＲＯＭ３０ｃ等の記憶部に記憶させてもよい。そして、当該新たな稼働率が、表示制御部３１４により稼働率表示画面ＤＰ２に表示される。以上で処理が終了する。 When the operator selects the calculation display 50 of the operation rate display screen DP2, the display control unit 314 displays the operation rate under various selected conditions (operation rate calculation period, aggregation period, etc.) on the operation rate display screen DP2. (S14). For example, the display control unit 314 displays the areas R14 to R16 and the like shown in FIG. 5 on the operation rate display screen DP2. If the operating rate under various selected conditions (operating rate calculation period, aggregation period, etc.) is not stored in the storage unit such as ROM 30c, the index calculation unit 312 newly calculates the operating rate under the conditions. , This may be stored in a storage unit such as ROM 30c. Then, the new operating rate is displayed on the operating rate display screen DP2 by the display control unit 314. This completes the process.
　次に、図８を用いて、ダッシュボード表示画面ＤＰ２一例を説明する。ダッシュボード表示画面ＤＰ２は、領域Ｒ２０～Ｒ２５と、算出表示８０とを含む。 Next, an example of the dashboard display screen DP2 will be described with reference to FIG. The dashboard display screen DP2 includes areas R20 to R25 and a calculation display 80.
　領域Ｒ２０には、現在の画面のステータスとして、「ダッシュボード」と表示されている。領域Ｒ２０の表示により、現在の画面がいずれのステータスであるかを容易に把握することができる。 In the area R20, "Dashboard" is displayed as the status of the current screen. By displaying the area R20, it is possible to easily grasp which status the current screen is in.
　ダッシュボード表示画面ＤＰ２の左上の領域Ｒ２１には、プラント１の停止可能性を有する異常の発生を示す情報と、その異常が発生した時間情報とが表示される。図８では、プラント１の停止可能性を有する異常の発生を示す情報の一例として、「噴破」という情報が大きなサイズの文字で表示される。その下には、「ＹＹＹＹ／ＭＭ／ＤＤ　ｈｈ：ｍｍ：ｓｓ」という現在の時間情報が表示される。この現在の時間情報は、例えば所定時間ごと（例えば１分ごと）に自動更新される。あるいは操作者の操作によって手動更新が可能であってもよい。この領域Ｒ２１に表示される情報によって、プラント１の操作者は、噴破という、プラント１の停止可能性を有する重大な異常が、ＹＹＹＹ年ＭＭ月ＤＤ日ｈｈ時ｍｍ分ｓｓ秒現在に発生したことを認識することができる。なお、変形例として、「噴破」という情報の直下の時間情報は、異常が発生した時刻としてもよい。 In the upper left area R21 of the dashboard display screen DP2, information indicating the occurrence of an abnormality having the possibility of stopping the plant 1 and information on the time when the abnormality occurred are displayed. In FIG. 8, as an example of the information indicating the occurrence of an abnormality having the possibility of stopping the plant 1, the information "blowing" is displayed in large characters. Below that, the current time information "YYYY / MM / DD hh: mm: ss" is displayed. This current time information is automatically updated, for example, every predetermined time (for example, every minute). Alternatively, manual update may be possible by the operation of the operator. According to the information displayed in this area R21, the operator of the plant 1 has experienced a serious abnormality having the possibility of stopping the plant 1, which is a blowout, as of MYYY, MM month, DD day, hh hours, mm minutes, ss seconds. You can recognize that. As a modification, the time information immediately below the information "blast" may be the time when the abnormality occurs.
　ダッシュボード表示画面ＤＰ２の左下の領域Ｒ２２には、「最新アラーム情報」として、プラントに関するプロセスデータが所定の状態となった場合の警告の発生を示す警告表示が表示される。警告表示は、プラント１の運転効率に影響を与えるプロセスデータの所定状態を表示するものであり、例えば、噴破のようなプラント１の停止可能性を有するものではないが、プラント１の運転効率を低下させるものである。領域Ｒ２２において、警告表示の発生履歴は、その発生時を示す時間情報と、その内容を示す情報とを発生時の順番に配列された状態で表示される。例えば、領域Ｒ２２の先頭には、「ＹＹＹＹ／ＭＭ／ＤＤ　ｈｈ：ｍｍ：ｓｓ」という時間情報と、「アラームＡ」という警告の内容を示す情報が対応付けられて表示されている。この領域Ｒ２２に表示される情報によって、プラント１の操作者は、アラームＡが、ＹＹＹＹ年ＭＭ月ＤＤ日ｈｈ時ｍｍ分ｓｓ秒に発生したことを認識することができる。同様にプラント１の操作者は、プラント１の運転効率に影響を与える他のプロセスデータの所定状態の発生時を示す時間情報とその内容を示す情報の履歴を認識することができる。 In the lower left area R22 of the dashboard display screen DP2, a warning display indicating the occurrence of a warning when the process data related to the plant is in a predetermined state is displayed as "latest alarm information". The warning display displays a predetermined state of process data that affects the operating efficiency of the plant 1, and does not have the possibility of stopping the plant 1 such as a blowout, but the operating efficiency of the plant 1. Is to reduce. In the area R22, the occurrence history of the warning display is displayed in a state in which the time information indicating the occurrence time and the information indicating the content thereof are arranged in the order of the occurrence time. For example, at the head of the area R22, the time information "YYYY / MM / DD hh: mm: ss" and the information indicating the content of the warning "alarm A" are displayed in association with each other. From the information displayed in this area R22, the operator of the plant 1 can recognize that the alarm A has occurred at HYYY year MM month DD day hh hours mm minutes ss seconds. Similarly, the operator of the plant 1 can recognize the time information indicating the time when a predetermined state of other process data affecting the operating efficiency of the plant 1 occurs and the history of the information indicating the contents thereof.
　ダッシュボード表示画面ＤＰ２の左側中央における領域Ｒ２１と領域Ｒ２２の間のスペースには、領域Ｒ２３が設けられる。領域Ｒ２３には、「機器・コンポーネント別」情報として、プラント１を構成する複数のコンポーネントが表示される。また、運転効率に影響を与える警告が発生した可能性があるコンポーネントは、他のコンポーネントと異なる態様で表示される。 Area R23 is provided in the space between the area R21 and the area R22 in the center on the left side of the dashboard display screen DP2. In the area R23, a plurality of components constituting the plant 1 are displayed as "equipment / component-specific" information. In addition, components that may have issued a warning that affects operating efficiency are displayed in a different manner from other components.
　具体的には、プラント１のコンポーネントとして、「プラント」、「ボイラ」、「タービン」、「ジェネレータ」及び「補機」が表示される。「ボイラ」は、火炉２等、ボイラを構成する部品に相当する。「タービン」は、タービン１００等、タービンを構成する部品に相当する。「補機」は、ポンプ７及びポンプ７ａ等、ボイラ等の主要部品には該当しない部品に相当する。また、「ジェネレータ」等、プラント１を構成し警告が発生する可能性が高い部品を適宜コンポーネントとして設定してもよい。また、運転効率に影響を与える警告の原因となるプロセスデータを特定し、これに基づいて、現時点において、警告が発生しているコンポーネント（例えば「ボイラ」及び「ジェネレータ」）を、例えば、赤色の背景色で表示し、警告が発生していないコンポーネント（例えば「プラント」及び「タービン」）を、例えば、緑色の背景色で表示し、評価項目が未設定のコンポーネント（例えば「補機」）を灰色で表示するように構成されている。更に、領域Ｒ２２に警告が継続しているアラームを赤字で表示し、領域Ｒ２３にそのアラームに対応するコンポーネントを赤の背景色で表示するようにして、運転効率に影響を与える警告の原因となるコンポーネントを容易に特定可能に構成してもよい。 Specifically, "plant", "boiler", "turbine", "generator" and "auxiliary machine" are displayed as the components of plant 1. The "boiler" corresponds to the parts constituting the boiler such as the furnace 2. The "turbine" corresponds to a component constituting the turbine, such as the turbine 100. "Auxiliary equipment" corresponds to parts such as pump 7 and pump 7a that do not correspond to main parts such as boilers. Further, a component such as a "generator" that constitutes the plant 1 and is likely to generate a warning may be appropriately set as a component. In addition, the process data that causes the warning that affects the operation efficiency is identified, and based on this, the component (for example, "boiler" and "generator") in which the warning is currently generated is, for example, red. Components that are displayed in the background color and no warning is generated (for example, "plant" and "turbine") are displayed in the background color of green, for example, and components for which evaluation items are not set (for example, "auxiliary equipment") are displayed. It is configured to be displayed in gray. Further, the alarm in which the warning is continued is displayed in red in the area R22, and the component corresponding to the alarm is displayed in the red background color in the area R23, which causes a warning that affects the operation efficiency. The components may be configured to be easily identifiable.
　ダッシュボード表示画面ＤＰ２の右下の領域Ｒ２５には、センサにより取得されたデータが異常値を示した回数を、センサごとに配列された態様で、異常の発生履歴が表示される。具体的には、「ＤＣＳアラーム集計」情報として、所定時間内、例えば、過去２４時間以内に、ＤＣＳ２０により判断された異常の回数を、センサごとに集計し、降順に並べたパレート図が示されている。なお、図８における「アラーム１」、「アラーム２」等は、具体的なセンサの識別情報が表示されるように構成してもよい。例えば、アラーム１として、特定の位置に設けられたＡＥセンサの識別情報が表示されてもよい。また、アラーム１として、特定のセンサにより検出される項目名が表示されてもよい。例えば、アラーム１として、補給水流量ｕ１を識別する情報が表示されてもよい。 In the area R25 at the lower right of the dashboard display screen DP2, the number of times the data acquired by the sensor shows an abnormal value is displayed in an arrangement for each sensor, and the history of occurrence of the abnormality is displayed. Specifically, as the "DCS alarm aggregation" information, a Pareto chart is shown in which the number of abnormalities determined by the DCS 20 is aggregated for each sensor within a predetermined time, for example, within the past 24 hours, and arranged in descending order. ing. The "alarm 1", "alarm 2", etc. in FIG. 8 may be configured to display specific sensor identification information. For example, as the alarm 1, the identification information of the AE sensor provided at a specific position may be displayed. Further, as the alarm 1, the item name detected by a specific sensor may be displayed. For example, as the alarm 1, information for identifying the make-up water flow rate u1 may be displayed.
　ダッシュボード表示画面ＤＰ２の右上の領域Ｒ２４には、プラント１の運転に関する効率等の指標がリアルタイムに表示される。ここで、リアルタイムで指標を表示するとは、所定期間におけるプラント１の運転に関する効率等の指標が、当該所定期間から所定時間が経過する前に表示することであってよい。所定時間の長さは、特に限定されず、例えば、１秒、５秒、１０秒、３０秒等の秒単位であってもよいし、１分、２分等の分単位であってもよい。しかしながら、所定期間の長さは、短いほどダッシュボード表示画面ＤＰ２に表示される情報のリアルタイム性が向上するため好ましい。当該所定時間の長さは、操作者等が任意に設定可能であってよい。 In the area R24 on the upper right of the dashboard display screen DP2, indicators such as efficiency related to the operation of the plant 1 are displayed in real time. Here, displaying the index in real time may mean displaying an index such as efficiency related to the operation of the plant 1 in a predetermined period before the predetermined time elapses from the predetermined period. The length of the predetermined time is not particularly limited, and may be, for example, in seconds such as 1 second, 5 seconds, 10 seconds, and 30 seconds, or in minutes such as 1 minute and 2 minutes. .. However, the shorter the length of the predetermined period is, the more the real-time property of the information displayed on the dashboard display screen DP2 is improved, which is preferable. The length of the predetermined time may be arbitrarily set by the operator or the like.
　例えば、領域Ｒ２４には、プラント１の安定的な運転のために重要な指標を縦軸とし、横軸を時間とする一又は複数のトレンドグラフが表示される。図８においては、例えば、上側に指標１及び指標２のトレンドグラフが重畳して表示され、下側に指標３及び指標４のトレンドグラフが重畳して表示されている。これらトレンドグラフの最右端の時刻は、これら指標が算出された最新の時刻である。そして、現在の時刻であるＹＹＹＹ年ＭＭ月ＤＤ日ｈｈ時ｍｍ分ｓｓ秒は、当該最右端の最新の時刻から未だ上述した所定時間が経過していない点に留意されたい。 For example, in the region R24, one or a plurality of trend graphs having an index important for stable operation of the plant 1 on the vertical axis and time on the horizontal axis are displayed. In FIG. 8, for example, the trend graphs of the index 1 and the index 2 are superimposed and displayed on the upper side, and the trend graphs of the index 3 and the index 4 are superimposed and displayed on the lower side. The time on the far right of these trend graphs is the latest time from which these indicators were calculated. It should be noted that the current time, MYYY year MM month DD day hh hours mm minutes ss seconds, has not yet passed the above-mentioned predetermined time from the latest time at the rightmost end.
　上述した通り、領域Ｒ２４の上側には指標１及び指標２が重畳して表示されているが、例えば、指標１はボイラ効率であってよく、指標２は発電端効率であってよい。このように、ボイラ効率（指標１）と発電端効率（指標２）とは、縦軸が重畳して表示されている。これにより、ボイラ効率と発電端効率との相関を容易に把握することが可能となり、特にプラント１全体の効率である発電端効率に対して、プラント１の重要なコンポーネントであるボイラのボイラ効率がどの程度の影響を及ぼしているかを視覚的且つ直感的に把握することが可能となる。なお、領域Ｒ２４に表示される指標は、プラント１の運転に関する指標であれば特に限定されず、操作者によって任意に選択されることができる。 As described above, the index 1 and the index 2 are superimposed and displayed on the upper side of the region R24. For example, the index 1 may be the boiler efficiency and the index 2 may be the power generation end efficiency. As described above, the boiler efficiency (index 1) and the power generation end efficiency (index 2) are displayed by superimposing the vertical axis. This makes it possible to easily grasp the correlation between the boiler efficiency and the power generation end efficiency, and in particular, the boiler efficiency of the boiler, which is an important component of the plant 1, is compared to the power generation end efficiency, which is the efficiency of the entire plant 1. It is possible to visually and intuitively grasp how much influence is exerted. The index displayed in the area R24 is not particularly limited as long as it is an index related to the operation of the plant 1, and can be arbitrarily selected by the operator.
　次に、図９を用いて、本実施形態に係る効率の表示に係る動作処理について説明する。図９は、当該動作処理の一例を示すフローチャートである。なお、以下に示すステップの内容や順序は一例であって、これに限られるものではない。以下では、プラント１は運転中であり、プロセスデータ取得部３１１がＤＣＳ２０を介してプラント１のプロセスデータを順次に取得しているものとする。 Next, the operation process related to the display of efficiency according to the present embodiment will be described with reference to FIG. FIG. 9 is a flowchart showing an example of the operation process. The contents and order of the steps shown below are examples, and are not limited to these. In the following, it is assumed that the plant 1 is in operation and the process data acquisition unit 311 sequentially acquires the process data of the plant 1 via the DCS20.
　指標算出部３１２は、所定時間が経過したか否かを判定する（Ｓ２０）。ここで、所定時間の長さは、特に限定されず、例えば、１秒、５秒、１０秒、３０秒等の秒単位であってもよいし、１分、２分等の分単位であってもよい。しかしながら、所定期間の長さは、短いほどダッシュボード表示画面ＤＰ２に表示される情報のリアルタイム性が向上するため好ましい。当該所定時間の長さは、操作者等が任意に設定可能であってよい。指標算出部３１２は、所定時間が経過したと判定するまで、ステップＳ２０を繰り返す。 The index calculation unit 312 determines whether or not a predetermined time has elapsed (S20). Here, the length of the predetermined time is not particularly limited, and may be, for example, in seconds such as 1 second, 5 seconds, 10 seconds, and 30 seconds, or in minutes such as 1 minute and 2 minutes. You may. However, the shorter the length of the predetermined period is, the more the real-time property of the information displayed on the dashboard display screen DP2 is improved, which is preferable. The length of the predetermined time may be arbitrarily set by the operator or the like. The index calculation unit 312 repeats step S20 until it is determined that the predetermined time has elapsed.
　所定期間が経過したと判定された場合（Ｓ２０；Ｙｅｓ）、指標算出部３１２は、プロセスデータ取得部３１１がＤＣＳ２０を介して取得したプロセスデータに基づいて、プラント１の運転に関する各種の効率や他の指標を算出する。特に、指標算出部３１２は、予めダッシュボード表示画面ＤＰ２において表示するように設定された効率や他の指標を算出する。指標算出部３１２が算出するプラント１の運転に関する効率は、例えば、プラント１に含まれるボイラの効率であるボイラ効率ηｂ、プラント１に含まれるタービンの効率であるタービン室効率ηｔ、及びプラント１全体の効率である発電端効率ηｎの少なくともいずれかを含んでもよい。 When it is determined that the predetermined period has elapsed (S20; Yes), the index calculation unit 312 has various efficiencies related to the operation of the plant 1 and others based on the process data acquired by the process data acquisition unit 311 via the DCS20. Calculate the index of. In particular, the index calculation unit 312 calculates the efficiency and other indexes set in advance to be displayed on the dashboard display screen DP2. The efficiency related to the operation of the plant 1 calculated by the index calculation unit 312 is, for example, the boiler efficiency η b , which is the efficiency of the boiler included in the plant 1, the turbine room efficiency η t , which is the efficiency of the turbine included in the plant 1, and the plant. 1 At least one of the power generation end efficiencies η n , which is the overall efficiency, may be included.
　次に、表示制御部３１４は、指標算出部３１２により算出された効率や他の指標に基づいて、ダッシュボード表示画面ＤＰ２の表示を更新する（Ｓ２２）。図８に示す例では、例えば、領域Ｒ２４の各種のトレンドグラフの時間軸（横軸）を最新の時刻の表記に更新した上で、指標算出部３１２が算出した効率や他の指標を当該トレンドグラフに追加して表示する。その後、処理はステップＳ２０に戻り、以降はステップＳ２０～Ｓ２２が繰り返される。これにより、操作者は、プラント１の運転に関する効率や他の指標をリアルタイムで確認することが可能となる。 Next, the display control unit 314 updates the display of the dashboard display screen DP2 based on the efficiency calculated by the index calculation unit 312 and other indexes (S22). In the example shown in FIG. 8, for example, after updating the time axis (horizontal axis) of various trend graphs in the region R24 to the latest time notation, the efficiency calculated by the index calculation unit 312 and other indexes are used as the trend. Add to the graph and display. After that, the process returns to step S20, and steps S20 to S22 are repeated thereafter. This allows the operator to check the efficiency and other indicators related to the operation of the plant 1 in real time.
　以上のとおり、本実施形態によれば、プラント１に異常が発生した場合において、操作者が把握すべきプラント１の状態を段階的かつ順番に表示することができるため、プラントの状態をわかりやすく操作者に示すことができる。特に、プラントは、監視すべき事象やパラメータが非常に多く、プラントの状態に変化が生じた場合には、そのことを効率的かつ迅速に操作者に伝える必要があるところ、本実施形態に係るシステム及び方法によりプラントの状態を適正化するための方法を確認することができ、どのような対応が必要であるか迅速に把握することができるようになる。 As described above, according to the present embodiment, when an abnormality occurs in the plant 1, the state of the plant 1 to be grasped by the operator can be displayed step by step and in order, so that the state of the plant can be easily understood. It can be shown to the operator. In particular, the plant has a large number of events and parameters to be monitored, and when a change occurs in the state of the plant, it is necessary to efficiently and promptly inform the operator of the change. It will be possible to confirm the method for optimizing the condition of the plant by the system and method, and to quickly grasp what kind of measures are necessary.
