通常、スマートグリッドの中にエレベータシステムを設置する場合、スマートグリッドの基幹装置となる中央監視制御装置から何らかの電力制限（電力上限値）指令を受けるが、エレベータシステムはその電力制限指令に応答して複数号機の消費電力を適切に制限しなければならない。   Normally, when installing an elevator system in a smart grid, the central supervisory control device, which is the core device of the smart grid, receives some power limit (power upper limit) command, but the elevator system responds to the power limit command. The power consumption of multiple units must be appropriately limited.

しかし、現状のエレベータシステムでは、複数号機のエレベータの消費電力信号を測定して送信できるが、スマートグリッドと連携しながら、複数号機のエレベータを適切に運転制御する技術については未だ提案されていない。   However, the current elevator system can measure and transmit the power consumption signals of the elevators of the plurality of units, but no technology has been proposed for appropriately controlling the operation of the elevators of the plurality of units while cooperating with the smart grid.

（第１の実施の形態）
図１は第1、第２の実施の形態に係るエレベータシステムの概略的な構成を示す図である。 Hereinafter, embodiments will be described with reference to the drawings.
(First embodiment)
FIG. 1 is a diagram showing a schematic configuration of an elevator system according to the first and second embodiments.

エレベータシステムは、複数の号機エレベータ１０，２０，３０と、号機共通処理装置５０とを含む構成である。号機共通処理装置５０は、スマートグリッドの中の基幹装置となる中央監視制御装置６０に接続されている。なお、複数の号機エレベータは、説明の便宜上、３台の号機エレベータ１０，２０，３０を例に挙げたが、その号機の台数は特に限定されるものでなく、３台以上であってもよい。   The elevator system includes a plurality of number elevators 10, 20, and 30 and a number common processing apparatus 50. The unit common processing device 50 is connected to a central monitoring and control device 60 serving as a backbone device in the smart grid. For convenience of explanation, the number of elevators of the number of three elevators 10, 20, and 30 is given as an example, but the number of the number of elevators is not particularly limited, and may be three or more. .

１号機エレベータ１０は、動力系電源１１から供給される交流電力を直流電力に変換するコンバータ１２、この変換された直流電力を所望の可変電圧及び可変周波数の交流電力に変換するインバータ１３、このインバータ１３から出力される交流電力を受けて回転駆動する巻上機（電動機を含む。以下、同じ）１４、外部から入力される運転指令信号に基づいてコンバータ１２及びインバータ１３のスイッチング素子をオン・オフ制御する１号機制御装置１５を備えている。   The first elevator 10 includes a converter 12 that converts AC power supplied from a power system power supply 11 into DC power, an inverter 13 that converts the converted DC power into AC power having a desired variable voltage and variable frequency, and this inverter A hoisting machine (including an electric motor; the same applies hereinafter) 14 that receives AC power output from the motor 13 and rotates and turns on / off switching elements of the converter 12 and the inverter 13 based on an operation command signal input from the outside. A first machine control device 15 for controlling is provided.

なお、巻上機１４には図示されていないがメインロープが巻き掛けられ、当該メインロープの各端部に乗りかご及びつりあい重りが吊下されている。   Although not shown in the drawings, a main rope is wound around the hoisting machine 14, and a car and a balance weight are suspended from each end of the main rope.

また、１号機エレベータ１０には、動力系電源１１の他、乗りかごなどの照明機器に電力を供給する照明系電源１６が導入されている。動力系電源１１の出力ラインには動力系電源用電力計１７が設けられ、一方、照明系電源１６の出力ラインには照明系電源用電力計１８が設けられている。   In addition to the power system power supply 11, the No. 1 elevator 10 has an illumination system power supply 16 that supplies power to lighting equipment such as a car. A power system power meter 17 is provided on the output line of the power system power source 11, while an illumination system power meter 18 is provided on the output line of the illumination system power source 16.

動力系電源用電力計１７は、乗りかごの昇降運転等に伴う動力系電源１１の消費電力を測定し、加算演算部１９に送出する。照明系電源用電力計１８は、乗りかごの各箇所に設置される照明機器の点灯等に伴う照明系電源１６の消費電力を測定し、同様に加算演算部１９に送出する。   The power system power meter 17 measures the power consumption of the power system power supply 11 that accompanies the raising / lowering operation of the car and sends it to the addition operation unit 19. The illumination system power meter 18 measures the power consumption of the illumination system power supply 16 associated with lighting of lighting equipment installed in each part of the car and sends it to the addition calculation unit 19 in the same manner.

加算演算部１９は、動力系電源用電力計１７及び照明系電源用電力計１８で測定された消費電力を加算することで１号機エレベータ１０の消費電力信号４１ａを求めた後、号機共通処理装置５０に送出する。   The addition calculation unit 19 adds the power consumption measured by the power system power meter 17 and the illumination system power meter 18 to obtain the power consumption signal 41a of the first elevator 10, and then the common machine processing unit 50.

２号機エレベータ２０及びＮ（Ｎ＝３）号機エレベータ３０は、１号機エレベータ１０と同様な構成を有している。すなわち、２号機エレベータ２０には１号機エレベータ１０の構成要素１１〜１９と同じ構成要素には符号２１〜２９を付し、また、Ｎ号機エレベータ３０には１号機エレベータ１０の構成要素１１〜１９と同じ構成要素には符号３１〜３９を付し、各号機エレベータ１０〜３０間の重複する構成要素の説明は省略する。   The second elevator 20 and the N (N = 3) elevator 30 have the same configuration as the first elevator 10. That is, the same components as the components 11 to 19 of the No. 1 elevator 10 are assigned to the No. 2 elevator 20, and the components 11 to 19 of the No. 1 elevator 10 are assigned to the No. N elevator 30. The same components as those in FIG. 1 are denoted by reference numerals 31 to 39, and the description of the overlapping components between the elevators 10 to 30 is omitted.

前記号機共通処理装置５０は、加算演算部５１と、運転指令装置５２とを含む構成である。   The common machine processing device 50 includes an addition operation unit 51 and an operation command device 52.

加算演算部５１は、１〜Ｎ号機エレベータ１０〜３０から送信されてくる各号機エレベータ１０〜３０の消費電力信号４１ａ、４１ｂ、４１ｃを加算することで全号機エレベータの総消費電力信号Ｐ０を求めた後、運転指令装置５２及び中央監視制御装置６０に送出する。   The addition calculation unit 51 obtains the total power consumption signal P0 of all the elevators by adding the power consumption signals 41a, 41b, 41c of the elevators 10-30 transmitted from the 1st to Nth elevators 10-30. After that, the data is sent to the operation command device 52 and the central monitoring control device 60.

ここで、中央監視制御装置６０は、管轄する電力系統の末端に接続される負荷機器であるエレベータシステムの総消費電力信号Ｐ０の状況を把握し、かつ、特定の地域内に設置される発電手段の発電量を考慮し、特定の建物に設置されるエレベータシステムで利用可能な電力制限信号（電力上限値）Ｐ１を決定し、運転指令装置５２に通知する。   Here, the central supervisory control device 60 grasps the status of the total power consumption signal P0 of the elevator system, which is a load device connected to the end of the power system under its jurisdiction, and is a power generation means installed in a specific area. The power limit signal (power upper limit value) P1 that can be used in the elevator system installed in a specific building is determined and notified to the operation command device 52.

運転指令装置５２は、スマートグリッドの中の中央監視制御装置６０から受け取るエレベータシステムで利用可能な電力制限信号Ｐ１とエレベータシステムの総消費電力信号Ｐ０とに基づき、当該総消費電力信号Ｐ０が電力制限信号Ｐ１以内となるように、例えば各号機の照明機器（機器数，使用電力量等）や乗りかごの最大積載荷重などを考慮し、予め定める複数の電力制限項目ごとに電力制限データを伴う運転指令信号４２ａ〜４２ｃを取得し、各号機制御装置１５，２５、３５に送出する。   The operation command device 52 is based on the power limit signal P1 that can be used in the elevator system received from the central monitoring control device 60 in the smart grid and the total power consumption signal P0 of the elevator system. Operation with power limit data for each of a plurality of power limit items determined in advance, taking into account the lighting equipment (number of devices, amount of power used, etc.) of each unit and the maximum load of the car so that it is within signal P1. The command signals 42a to 42c are acquired and sent to the respective machine control devices 15, 25 and 35.

図２はコンピュータを用いた運転指令装置５２の一構成例を示す図である。
コンピュータを用いた運転指令装置５２は、各号機エレベータ１０〜３０の消費電力信号４１ａ、４１ｂ、４１ｃをソフトウエア的に加算処理できるので、図１に示す号機共通処理装置５０から加算演算部５１を削除して電力制限処理を行うことができる。 FIG. 2 is a diagram showing a configuration example of the operation command device 52 using a computer.
Since the operation command device 52 using a computer can add the power consumption signals 41a, 41b and 41c of the elevators 10 to 30 by software, the addition calculation unit 51 is added from the common machine processing device 50 shown in FIG. It is possible to delete the power limit process.

運転指令装置５２は、少なくとも電力制限処理プログラムを記憶するＲＯＭで構成されるプログラムデータ記憶部５３、この電力制限処理プログラムに従って一連の電力制限処理を行うＣＰＵで構成される運転指令処理部５４、入力インタフェース５５を通して取り込む各種の電力データ，例えば４１ａ、４１ｂ、４１ｃ、Ｐ１や電力制限処理等に必要な各種データ等を記憶するＲＡＭで構成される補助記憶装置５６が設けられている。   The operation command device 52 includes a program data storage unit 53 configured by a ROM that stores at least a power limitation processing program, an operation command processing unit 54 configured by a CPU that performs a series of power limitation processing according to the power limitation processing program, and an input. There is provided an auxiliary storage device 56 composed of a RAM for storing various kinds of power data fetched through the interface 55, for example, various data necessary for 41a, 41b, 41c, P1, power restriction processing, and the like.

また、運転指令装置５２は、運転指令処理部５４による電力制限処理結果の電力低減に関する運転指令信号４２ａ〜４２ｃを各号機エレベータ１０〜３０へ送信するための出力インタフェース５７、電力制限処理等に必要な制御指示や設定データ等を入力するためのキーボード、マウスなどの入力部５８、表示部５９等が設けられている。   Further, the operation command device 52 is necessary for the output interface 57 for transmitting the operation command signals 42a to 42c relating to the power reduction of the result of the power limitation process by the operation command processing unit 54 to the elevators 10 to 30, the power limitation process, and the like. An input unit 58 such as a keyboard and a mouse for inputting various control instructions and setting data, a display unit 59, and the like are provided.

なお、入力インタフェース５５及び出力インタフェース５７は、伝送機能や一時的にデータを記憶する機能を備えたものである。   Note that the input interface 55 and the output interface 57 have a transmission function and a function of temporarily storing data.

補助記憶装置５６には、例えば各号機エレベータ１０〜３０の消費電力信号４１ａ、４１ｂ、４１ｃを含む総消費電力Ｐ０（＝４１ａ＋４１ｂ＋４１ｃ）や電力制限信号Ｐ１を記憶し管理する電力管理テーブル５６ａ（図３参照）、予め定める電力制限項目ごとに電力制限データ（電力低減データ）及び電力制限解除データ（電力増加データ）を規定する設定データ記憶部５６ｂ、時間を計測するタイマー部５６ｃ及び処理データ記憶部５６ｄなどが設けられている。なお、電力制限データ（電力低減データ）としては、予め定める電力制限固定値、あるいは複数回にわたって電力制限信号Ｐ１を受けることを想定して予め電力制限する所定の制限割合（例えば５％）、さらに号機エレベータに対する運転許可、運転休止とする電力低減に関するデータを含むものである。   The auxiliary storage device 56 stores, for example, the total power consumption P0 (= 41a + 41b + 41c) including the power consumption signals 41a, 41b and 41c of the elevators 10 to 30 and the power limit signal P1, and manages the power management table 56a (FIG. 3). See), a setting data storage unit 56b that prescribes power limit data (power reduction data) and power limit release data (power increase data) for each predetermined power limit item, a timer unit 56c that measures time, and a processing data storage unit 56d. Etc. are provided. As the power limit data (power reduction data), a predetermined power limit fixed value, or a predetermined limit ratio (for example, 5%) that limits power in advance assuming that the power limit signal P1 is received multiple times, It includes data related to power reduction for operation permission and operation suspension for the elevator.

運転指令処理部５４は、機能的に分けると、照明減光処理手段５４Ａ、号機運転制限処理手段５４Ｂ、照明減光解除手段５４Ｃ、号機運転制限解除手段５４Ｄが設けられている。   The operation command processing unit 54, when functionally divided, is provided with an illumination dimming processing means 54A, a number machine operation restriction processing means 54B, an illumination dimming release means 54C, and a number machine operation restriction release means 54D.

照明減光処理手段５４Ａは、中央監視制御装置６０から電力制限信号Ｐ１を受けたとき、電力制限項目の１つである各号機エレベータの乗りかごの照明を減光する処理を行う。号機運転制限処理手段５４Ｂは、前述する電力制限信号Ｐ１を受けたとき、予め定めた電力制限項目ごとに運転に関する電力制限処理を実行する。   When the illumination dimming processing means 54A receives the power limit signal P1 from the central supervisory control device 60, the illumination dimming processing means 54A performs a process of dimming the illumination of each elevator car that is one of the power limit items. When the unit operation restriction processing means 54B receives the power restriction signal P1 described above, the unit operation restriction processing means 54B executes a power restriction process relating to operation for each predetermined power restriction item.

照明減光解除手段５４Ｃ及び号機運転制限解除手段５４Ｄは、中央監視制御装置６０から電力制限解除信号Ｐ１´を受けたとき、予め定める電力制限解除データ（電力増加データ）に基づき既に実施中の電力制限を解除するか、あるいは予め定める電力制限解除割合に従って少しずつ電力制限を解除していく処理を行うものであって、詳細は後記する。   When the illumination dimming canceling means 54C and the number machine operation restriction releasing means 54D receive the power restriction canceling signal P1 ′ from the central monitoring control device 60, the power already being executed based on the predetermined power restriction releasing data (power increase data). The process of releasing the restriction or releasing the power restriction little by little according to a predetermined power restriction release ratio is described in detail later.

次に、以上のようなエレベータシステムにおける電力制限の処理手順について、図４を参照して説明する。なお、電力制限処理の開始に先立ち、プログラムデータ記憶部５３に記憶される電力制限処理プログラム（図４（ａ）、（ｂ）参照）を読み出して補助記憶装置５６に格納し、ワークメモリとして使用する。   Next, the power restriction processing procedure in the elevator system as described above will be described with reference to FIG. Prior to the start of the power limiting process, the power limiting process program (see FIGS. 4A and 4B) stored in the program data storage unit 53 is read out and stored in the auxiliary storage device 56 and used as a work memory. To do.

運転指令処理部５４は、電力制限処理を開始すると（Ｓ１）、照明減光処理手段５４Ａを実行する。   When starting the power limiting process (S1), the operation command processing unit 54 executes the illumination dimming processing unit 54A.

照明減光処理手段５４Ａは、中央監視制御装置６０からエレベータシステムで利用可能な電力制限信号（電力上限値）Ｐ１を取得し、また、１〜Ｎ（Ｎ＝３）号機エレベータ１０〜３０から消費電力信号４１ａ、４１ｂ、４１ｃを収集して補助記憶装置５６の電力管理テーブル５６ａに記憶した後、各消費電力信号４１ａ、４１ｂ、４１ｃを加算演算し、全号機エレベータ１０〜３０の総消費電力信号Ｐ０を取得し（Ｓ２）、同様に電力管理テーブル５６ａに記憶する。   The illumination dimming processing means 54A obtains a power limit signal (power upper limit value) P1 that can be used in the elevator system from the central supervisory control device 60, and is also consumed from the elevators 10 to 30 (N = 3). After collecting the power signals 41a, 41b and 41c and storing them in the power management table 56a of the auxiliary storage device 56, the power consumption signals 41a, 41b and 41c are added and calculated, and the total power consumption signals of all the elevators 10 to 30 are calculated. P0 is acquired (S2) and similarly stored in the power management table 56a.

しかる後、照明減光処理手段５４Ａは、電力制限信号Ｐ１と総消費電力Ｐ０との大小関係を比較する（Ｓ３）。ここで、電力制限信号Ｐ１が大きければ、処理継続（Ｓ２２）を条件にステップＳ２に戻る。総消費電力Ｐ０が大きければ、全号機エレベータの乗りかごの照明を減光に関する電力制限データ（例えば現在よりも５％低減データ）を伴う運転指令信号４２ａ，４２ｂ，４２ｃを各号機制御装置１５，２５，３５に送出し、消費電力の低下を図る。   Thereafter, the illumination dimming processing means 54A compares the magnitude relationship between the power limit signal P1 and the total power consumption P0 (S3). If the power limit signal P1 is large, the process returns to step S2 on condition that the process is continued (S22). If the total power consumption P0 is large, the operation command signals 42a, 42b, 42c accompanied by power restriction data (for example, 5% reduction data from the present) for dimming the lights of the elevator cars of all the elevators are sent to the respective control devices 15, 25, 35 to reduce power consumption.

乗りかごの照明減光方法としては、各乗りかご内の利用客の影響を考慮し、例えば一律に５％ずつ減光するとか、あるいは乗りかごの最大積載量や乗りかごの照明使用電力量に応じて割合を変化させて減光してもよく、予め設定データ記憶部５６ｂに照明減光の電力制限データが規定される。   As for the lighting dimming method of the car, considering the influence of passengers in each car, for example, it is reduced by 5% uniformly, or the maximum loading capacity of the car and the lighting power consumption of the car Accordingly, the light may be dimmed by changing the ratio, and power limitation data for illumination dimming is defined in advance in the setting data storage unit 56b.

しかる後、照明減光処理手段５４Ａは、照明減光後の電力測定を行った後（Ｓ５）、エレベータシステムの総消費電力Ｐ０が電力制限信号Ｐ１内に入っているか否かを評価する（Ｓ６）。   Thereafter, the illumination dimming processing unit 54A performs power measurement after illumination dimming (S5), and then evaluates whether or not the total power consumption P0 of the elevator system is within the power limit signal P1 (S6). ).

電力測定処理は、図４（ｂ）に示すように、補助記憶装置５６等に設定されるタイマー部５６ｃをスタートさせた後（Ｓ３１）、１〜３号機エレベータ１０〜３０から各号機エレベータの消費電力信号４１ａ、４１ｂ、４１ｃを取り込んで補助記憶装置５６の処理データ記憶部５６ｄに記憶した後（Ｓ３２）、これら各号機消費電力信号４１ａ、４１ｂ、４１ｃを加算演算して全号機エレベータ１０〜３０の総消費電力Ｐ０を取得する（Ｓ３３）。   As shown in FIG. 4B, the power measurement process starts the timer unit 56c set in the auxiliary storage device 56 and the like (S31), and then consumes each elevator from No. 1 to No. 3 elevators 10-30. After the power signals 41a, 41b and 41c are taken in and stored in the processing data storage unit 56d of the auxiliary storage device 56 (S32), these unit power consumption signals 41a, 41b and 41c are added and calculated to all the elevators 10-30. The total power consumption P0 is acquired (S33).

さらに、タイマー部５６ｂが予め定めた所定時間を経過したか否かを判断し（Ｓ３４）、経過していない場合にはステップＳ３２に戻って同様の処理を繰り返し実行する。ステップＳ３４において、タイマー部５６ｃの計測時間が所定時間を経過したと判断したとき、エレベータシステムの総消費電力Ｐ０を所定時間で除算し、時間平均電力値となる総消費電力Ｐ０を算出し、電力管理テーブル５６ａの総消費電力信号Ｐ０を書き換える（Ｓ３５）。このとき、各号機エレベータ１０〜３０の時間平均電力値に相当する消費電力信号４１ａ、４１ｂ、４１ｃも同時に書き換えてもよい。   Further, the timer unit 56b determines whether or not a predetermined time has elapsed (S34), and if it has not elapsed, the process returns to step S32 to repeat the same processing. When it is determined in step S34 that the measurement time of the timer unit 56c has passed the predetermined time, the total power consumption P0 of the elevator system is divided by the predetermined time to calculate the total power consumption P0 that is the time average power value. The total power consumption signal P0 in the management table 56a is rewritten (S35). At this time, the power consumption signals 41a, 41b and 41c corresponding to the time average power values of the elevators 10 to 30 may be rewritten simultaneously.

電力管理テーブル５６ａの総消費電力信号Ｐ０を書き換えた後、タイマー部５６ｃをクリアし（Ｓ３６）、図４（ａ）に示すメイン処理に戻る（Ｓ３７）。   After rewriting the total power consumption signal P0 in the power management table 56a, the timer unit 56c is cleared (S36), and the process returns to the main process shown in FIG. 4A (S37).

このように消費電力の時間平均化処理を行うことで、頻繁に制限動作が変化することを避け、エレベータシステムの制御の安定化を図るものである。   By performing the power consumption time averaging process in this way, it is possible to avoid frequent changes in the limiting operation and stabilize the control of the elevator system.

メイン処理となるステップＳ６では、照明減光後のエレベータシステムの総消費電力Ｐ０と電力制限信号Ｐ１との大小関係を比較し、かご照明の減光を行った効果を評価する。   In step S6 which is the main process, the magnitude relationship between the total power consumption P0 and the power limit signal P1 of the elevator system after the illumination is dimmed is compared, and the effect of the dimming of the car illumination is evaluated.

すなわち、照明減光処理手段５４Ａは、総消費電力Ｐ０と電力制限信号Ｐ１との大小関係を比較した結果、電力制限信号Ｐ１が大きければ、処理継続（Ｓ２２）を条件にステップＳ２に戻って同様の処理を繰り返し実行する。一方、総消費電力Ｐ０が大きければ、号機運転制限処理手段５４Ｂを実行する。   That is, the illumination dimming processing unit 54A compares the magnitude relationship between the total power consumption P0 and the power limit signal P1, and as a result, if the power limit signal P1 is large, the process returns to step S2 on the condition that the process is continued (S22). Repeat the process. On the other hand, if the total power consumption P0 is large, the number machine operation restriction processing means 54B is executed.

号機運転制限処理手段５４Ｂは、予め定める電力制限項目の１つである加速度・定格速度の電力制限処理を実行する。１号機エレベータ１０から順次電力制限処理を行うために、補助記憶装置５６に設定されるカウンタメモリ（図示せず）にｎ＝１を設定し（Ｓ７）、かつ、設定データ記憶部５６ｂに予め設定される加速度・定格速度に関する電力制限データ（例えば現在よりも５％低減するデータ）を伴う運転指令信号４２ａを送出し、１号機エレベータ１０の巻上機１４の加速度・定格速度を引き下げた後（Ｓ８）、電力測定を行う（Ｓ９）。電力測定処理は、既に図４（ｂ）で説明した通りであって、ここでは重複する説明は省略する。   Unit operation restriction processing means 54B executes acceleration / rated speed power restriction processing, which is one of predetermined power restriction items. In order to sequentially perform the power limiting process from the first elevator 10, the counter memory (not shown) set in the auxiliary storage device 56 is set to n = 1 (S7) and set in the setting data storage unit 56b in advance. After sending an operation command signal 42a with power limit data (for example, data that is reduced by 5% from the current value) regarding the acceleration / rated speed to be lowered and lowering the acceleration / rated speed of the hoisting machine 14 of the first elevator 10 ( S8), power measurement is performed (S9). The power measurement process has already been described with reference to FIG. 4B, and redundant description is omitted here.

号機運転制限処理手段５４Ｂは、電力測定を行った後、加速度・定格速度制限を行った効果を評価するために、再び電力制限信号Ｐ１とエレベータシステムの総消費電力Ｐ０との大小関係を比較する（Ｓ１０）。   The unit operation restriction processing means 54B compares the magnitude relationship between the power restriction signal P1 and the total power consumption P0 of the elevator system again in order to evaluate the effect of the acceleration / rated speed restriction after the power measurement. (S10).

ここで、電力制限信号Ｐ１が大きければ、処理継続（Ｓ２２）を条件にステップＳ２に戻って同様の処理を繰り返し実行する。エレベータシステムの総消費電力Ｐ０が大きければ、全号機エレベータの加速度・定格速度制限の実施終了か否かを判断し（Ｓ１１）、未だ全号機Ｎの制限処理が終了していない場合にはカウンタメモリを＋１インクリメントし（Ｓ１２）、次の２号機エレベータ２０の巻上機１４の加速度・定格速度を引き下げた後（Ｓ８）、同様の処理を繰り返すことで消費電力の低下を図る（Ｓ８〜Ｓ１２）。   Here, if the power limit signal P1 is large, the process returns to step S2 on condition that the process is continued (S22), and the same process is repeated. If the total electric power consumption P0 of the elevator system is large, it is determined whether or not the acceleration / rated speed restriction of all the elevators is finished (S11). If the restriction process for all the cars N has not been finished yet, the counter memory Is incremented by +1 (S12), and the acceleration / rated speed of the hoisting machine 14 of the next No. 2 elevator 20 is lowered (S8), and the same processing is repeated to reduce the power consumption (S8 to S12). .

号機運転制限処理手段５４Ｂは、Ｎ（Ｎ＝３）号機エレベータ３０まで加速度・定格速度に関する電力制限処理を行っても、総消費電力Ｐ０が電力制限信号Ｐ１より大きければ、次の電力制限項目である運転方向を制限する処理を行う。   Unit operation restriction processing means 54B performs the following power restriction item if total power consumption P0 is greater than power restriction signal P1 even if the power restriction process related to acceleration / rated speed is performed up to N (N = 3) elevator 30 A process for limiting a certain driving direction is performed.

号機運転制限処理手段５４Ｂは、各号機エレベータ１０〜３０における乗りかごの積載荷重と各号機エレベータ１０〜３０の運転指令信号から得られる運転方向とから回生方向への運転かを判断し、回生運転可能と判断された号機のみを運転許可する電力制限データを伴う運転指令信号４２ａ，４２ｂ，４２ｃを送出し（Ｓ１３）、消費電力の低下を図る。 The unit operation restriction processing means 54B determines whether the operation is in the regenerative direction from the loading direction of the car in each of the elevators 10-30 and the operation direction obtained from the operation command signal of each of the elevators 10-30. Operation command signals 42a, 42b, and 42c accompanied by power restriction data for permitting operation of only the units determined to be possible are sent out (S13) to reduce power consumption.

しかる後、号機運転制限処理手段５４Ｂは、図４（ｂ）に示す電力測定を行った後（Ｓ１４）、運転方向制限を行った効果を評価するために、再び電力制限信号Ｐ１と全号機エレベータの総消費電力Ｐ０との大小関係を比較する（Ｓ１５）。電力制限信号Ｐ１が大きければ、処理継続（Ｓ２２）を条件にステップＳ２に戻る。総消費電力Ｐ０が大きければ、最後の運転制限項目となる号機エレベータの運転を休止する電力制限データを伴う運転指令信号４２ａ，４２ｂ，４２ｃを送出し（Ｓ１３）、消費電力の低下を図る。   After that, after performing the power measurement shown in FIG. 4B (S14), the unit operation restriction processing means 54B again measures the power restriction signal P1 and all the unit elevators in order to evaluate the effect of restricting the operation direction. Are compared with the total power consumption P0 (S15). If the power limit signal P1 is large, the process returns to step S2 on condition that the process is continued (S22). If the total power consumption P0 is large, operation command signals 42a, 42b, and 42c accompanied by power restriction data for stopping the operation of the elevator that is the last operation restriction item are transmitted (S13), and the power consumption is reduced.

号機運転制限処理手段５４Ｂは、補助記憶装置５６に設定されるカウンタメモリ（図示せず）にｎ＝１を設定し（Ｓ１６）、１号機エレベータ１０の運転を休止する電力制限データを伴う運転指令信号４２ａを送出し（Ｓ１７）、その後に図４（ｂ）に示す電力測定を行う（Ｓ１８）。   The unit operation restriction processing means 54B sets n = 1 in a counter memory (not shown) set in the auxiliary storage device 56 (S16), and an operation command with power restriction data for stopping the operation of the first unit elevator 10 The signal 42a is transmitted (S17), and then the power measurement shown in FIG. 4B is performed (S18).

さらに、運転休止による効果を評価するために、再び電力制限信号Ｐ１と全号機エレベータ１０〜３０の総消費電力Ｐ０との大小関係を比較する（Ｓ１９）。電力制限信号Ｐ１が大きければ、処理継続（Ｓ２２）を条件にステップＳ２に戻る。総消費電力Ｐ０が大きければ、全号機エレベータの休止制限の実施終了か否かを判断し（Ｓ２０）、未だ全号機制限終了でない場合にはカウンタメモリを＋１インクリメントし（Ｓ２１）、次の号機となる２号機エレベータ２０を休止する電力制限データを伴う運転指令信号４２ａを送出し、消費電力の低下を図る。   Furthermore, in order to evaluate the effect due to the suspension of operation, the magnitude relationship between the power limit signal P1 and the total power consumption P0 of all the elevators 10 to 30 is compared again (S19). If the power limit signal P1 is large, the process returns to step S2 on condition that the process is continued (S22). If the total power consumption P0 is large, it is determined whether or not the stop restriction of all the elevators is finished (S20). If the restriction on all the cars is not finished yet, the counter memory is incremented by +1 (S21). The operation command signal 42a accompanied by the power limit data for stopping the second elevator 20 is sent to reduce power consumption.

この運転休止の処理はＮ（Ｎ＝３）号機まで順次実施し、一連の電力制限処理を終了する。   The operation stop process is sequentially performed up to N (N = 3), and a series of power limiting processes is completed.

従って、以上のような実施の形態によれば、例えばスマートグリッド内の消費電力の増加または発電量の減少等によって電力供給に余裕が無くなったとき、中央監視制御装置６０から消費電力を低減すべく電力制限信号Ｐ１の指令が出たとき、運転指令装置５２が乗りかごの照明の減光、巻上機１４の加速度・定格速度の制限、各号機の運転方向の制限（回生方向となる号機エレベータの運転許可。以下、同じ）、各号機の運転休止等に関する電力制限を段階的にかけていくので、中央監視制御装置６０からの電力制限信号Ｐ１指令に確実に応えることができ、ひいてはスマートグリッドに十分適用可能なエレベータシステムを実現できる。 Therefore, according to the embodiment as described above, when there is no room for power supply due to, for example, an increase in power consumption in the smart grid or a decrease in power generation amount, the central supervisory control device 60 should reduce power consumption. When the command for the power limit signal P1 is issued, the operation command device 52 dims the lighting of the car, limits the acceleration / rated speed of the hoisting machine 14, limits the driving direction of each unit (the elevator in the regeneration direction) The same applies to the following.) Since the power limitation related to the suspension of operation of each unit is applied in stages, the power limitation signal P1 command from the central supervisory control device 60 can be surely responded, which is sufficient for smart grids. Applicable elevator system can be realized.

また、中央監視制御装置６０から消費電力を制限する電力制限信号Ｐ１の指令を受けたとき、予め定める制限項目を段階的に選択し、電力制限をかけていくので、電力制限信号Ｐ１と全号機エレベータの総消費電力Ｐ０との差が徐々に小さくなるようにフィードバック制御による運転を実施するので、全号機エレベータの総消費電力Ｐ０を徐々に低減しつつ、適切に複数号機エレベータの運転制御を実施できる。   In addition, when receiving a command of the power limit signal P1 for limiting power consumption from the central supervisory control device 60, a predetermined limit item is selected step by step and the power limit is applied. Since the operation by feedback control is performed so that the difference from the total power consumption P0 of the elevator is gradually reduced, the total power consumption P0 of all the elevators is gradually reduced and the operation control of the multiple elevators is appropriately performed. it can.

なお、上記の第１の実施形態では、タイマー部５６ｃで計測する所定時間は、予め定める一定時間としたが、昼間におけるエレベータ利用者の混雑時間とそれ以外の非混雑時間とに分けて、所定時間を異ならせてもよい。   In the first embodiment, the predetermined time measured by the timer unit 56c is a predetermined time. However, the predetermined time is divided into the congestion time of the elevator user in the daytime and the other non-congestion time. You may vary the time.

次に、既に段階的にかけられた電力制限を逆に段階的に電力制限解除の処理手順について説明する。   Next, the processing procedure for canceling the power limit in a stepwise manner will be described in reverse of the power limit that has been applied in a stepwise manner.

この電力制限解除処理は、図２と同様な構成の運転指令装置５２が用いられる。運転指令装置５２を構成するプログラムデータ記憶部５３には、図５に示す処理手順を規定する電力制限解除処理プログラムが格納されている。また、運転指令処理部５４は、機能的には既に図２で説明したように、照明減光解除手段５４Ｃ及び号機運転制限解除手段５４Ｄを実行する。   For this power restriction release processing, the operation command device 52 having the same configuration as that in FIG. 2 is used. The program data storage unit 53 constituting the operation command device 52 stores a power limit release processing program that defines the processing procedure shown in FIG. The operation command processing unit 54 functionally executes the illumination dimming canceling means 54C and the number machine operation restriction releasing means 54D as already described with reference to FIG.

先ず、照明減光解除手段５４Ｃは、中央監視制御装置６０から電力制限解除信号（電力上限値）Ｐ１´を受けたとき、各号機エレベータ１０〜３０の乗りかごの照明を減光する電力制限解除データを伴う運転指令信号４２ａ，４２ｂ，４２ｃを送出し、電力制限を解除する処理を行う。   First, the illumination dimming cancellation means 54C receives the power limitation cancellation signal (power upper limit value) P1 ′ from the central monitoring and control device 60, and cancels the power limitation that dims the lighting of the elevator cars 10-30. Operation command signals 42a, 42b, and 42c accompanied by data are transmitted to perform processing for releasing the power restriction.

号機運転制限解除手段５４Ｄは、同じく電力制限解除信号（電力上限値）Ｐ１´を受けたとき、複数の電力制限項目ごとに順次電力制限解除データを伴う運転指令信号４２ａ，４２ｂ，４２ｃを送出し、電力制限を解除する処理を行う。   Similarly, when the power unit operation restriction release means 54D receives the power restriction release signal (power upper limit value) P1 ′, it sequentially sends out operation command signals 42a, 42b, and 42c with power restriction release data for each of the plurality of power restriction items. Then, the process of canceling the power limit is performed.

次に、図５を参照して電力制限解除処理について説明する。   Next, the power restriction release process will be described with reference to FIG.

先ず、電力制限解除処理の開始に先立ち、プログラムデータ記憶部５３に記憶される電力制限解除処理プログラム（図５参照）を読み出してワークメモリとなる例えば補助記憶装置５６に格納し、この電力制限解除処理プログラムに基づいて一連の解除処理を実行する。   First, prior to the start of the power limit release processing, the power limit release processing program (see FIG. 5) stored in the program data storage unit 53 is read and stored in, for example, the auxiliary storage device 56 serving as a work memory. A series of release processing is executed based on the processing program.

すなわち、運転指令処理部５４は、電力制限解除処理を開始すると（Ｓ５１）、照明減光解除手段５４Ｃを実行する。   That is, the operation command processing unit 54 executes the illumination dimming canceling unit 54C when starting the power limit canceling process (S51).

照明減光解除手段５４Ｃは、中央監視制御装置６０からエレベータシステムで利用可能な電力制限解除信号（電力上限値）Ｐ１´を取り込み、また、１〜３号機エレベータ１０〜３０から各号機消費電力信号４１ａ、４１ｂ、４１ｃを取り込み、それぞれ補助記憶装置５６の電力管理テーブル５６ａに記憶した後、各号機消費電力信号４１ａ、４１ｂ、４１ｃを加算演算し、全号機からなるエレベータシステムの総消費電力信号Ｐ０´を求めた後、同様に電力管理テーブル５６ａに記憶する（Ｓ５２）。   The illumination dimming canceling means 54C takes in the power limit canceling signal (power upper limit value) P1 ′ that can be used in the elevator system from the central supervisory control device 60, and each unit No. 1-3 elevator 10-30 power consumption signal 41a, 41b, and 41c are taken in and stored in the power management table 56a of the auxiliary storage device 56, respectively, and the unit power consumption signals 41a, 41b, and 41c are added and calculated, and the total power consumption signal P0 of the elevator system composed of all the units. After obtaining ', it is similarly stored in the power management table 56a (S52).

しかる後、照明減光解除手段５４Ｃは、電力制限解除信号Ｐ１´と総消費電力Ｐ０´との大小関係を比較する（Ｓ５３）。ここで、総消費電力Ｐ０´が大きければ、処理継続（Ｓ７２）を条件にステップＳ５２に戻って処理を繰り返す。電力制限解除信号Ｐ１´が大きければ、例えば全号機エレベータの乗りかごのかご照明の減光（電力制限値）を完全に解除するか、あるいは現在よりも５％復帰するなどの電力制限解除データを伴う運転指令信号４２ａ，４２ｂ，４２ｃを送出し、通常の状態に戻していく（Ｓ５４）。   Thereafter, the illumination dimming canceling means 54C compares the magnitude relationship between the power limit canceling signal P1 ′ and the total power consumption P0 ′ (S53). If the total power consumption P0 ′ is large, the process returns to step S52 on the condition that the process is continued (S72) and the process is repeated. If the power limit release signal P1 ′ is large, for example, the power limit release data such as completely canceling the dimming (power limit value) of the car lighting of all the elevators or returning 5% from the current level. The accompanying operation command signals 42a, 42b, 42c are sent out to return to the normal state (S54).

しかる後、照明減光解除手段５４Ｃは、電力測定を行った後（Ｓ５５）、エレベータシステムの総消費電力Ｐ０´が電力制限解除信号Ｐ１´まで増加してきたか否かを評価する（Ｓ５６）。   Thereafter, the illumination dimming canceling means 54C performs power measurement (S55), and then evaluates whether or not the total power consumption P0 ′ of the elevator system has increased to the power limit canceling signal P1 ′ (S56).

なお、電力測定処理は、図５（ｂ）に示すように、補助記憶装置５６等に設定されるタイマー部５６ｃをスタートさせた後（Ｓ８１）、１〜Ｎ号機エレベータ１０〜３０から各号機消費電力信号４１ａ、４１ｂ、４１ｃを取り込んで処理データ記憶部５６ｄに記憶した後（Ｓ８２）、これら各号機消費電力信号４１ａ、４１ｂ、４１ｃを加算して総消費電力Ｐ０´を求める（Ｓ８３）。   In addition, as shown in FIG.5 (b), after starting the timer part 56c set to the auxiliary | assistant storage device 56 grade | etc., As shown in FIG.5 (b) (S81), 1 unit N elevators 10-30 use each unit consumption. After capturing the power signals 41a, 41b, 41c and storing them in the processing data storage unit 56d (S82), these unit power consumption signals 41a, 41b, 41c are added to obtain the total power consumption P0 ′ (S83).

さらに、タイマー部５６ｂの計測時間が予め定める所定時間を経過したか否かを判断し（Ｓ８４）、経過していない場合にはステップＳ８２に戻って同様の処理を繰り返し実行する。その結果、ステップＳ８４において、タイマー部５６ｃの計測時間が所定時間を経過したと判断したとき、エレベータシステムの総消費電力Ｐ０´を所定時間で除算し、時間平均電力値である減光解除後の総消費電力信号Ｐ０´を算出し、電力管理テーブル５６ａの総消費電力信号Ｐ０´を書き換える（Ｓ８５）。このとき、各号機エレベータ１０〜３０の時間平均電力値に相当する消費電力信号４１ａ、４１ｂ、４１ｃも同時に書き換えてもよい。   Further, it is determined whether or not the predetermined measurement time of the timer unit 56b has elapsed (S84), and if it has not elapsed, the process returns to step S82 to repeat the same processing. As a result, in step S84, when it is determined that the measurement time of the timer unit 56c has passed the predetermined time, the total power consumption P0 ′ of the elevator system is divided by the predetermined time, and after the dimming is canceled, which is the time average power value. The total power consumption signal P0 ′ is calculated, and the total power consumption signal P0 ′ in the power management table 56a is rewritten (S85). At this time, the power consumption signals 41a, 41b and 41c corresponding to the time average power values of the elevators 10 to 30 may be rewritten simultaneously.

電力管理テーブル５６ａの総消費電力信号Ｐ０´を書き換えた後、タイマー部５６ｃをクリアし（Ｓ８６）、図５（ａ）に示すメイン処理に戻る（Ｓ８７）。   After rewriting the total power consumption signal P0 ′ in the power management table 56a, the timer unit 56c is cleared (S86), and the process returns to the main process shown in FIG. 5A (S87).

このように電力の時間平均化処理を行うことで、頻繁に制限解除動作が変化することを避け、エレベータシステムの制御の安定化を図るものである。   By performing the time averaging process of electric power in this way, it is possible to avoid frequent change of the restriction release operation and to stabilize the control of the elevator system.

なお、タイマー部５６ｃを動作させる所定時間は、予め任意に設定データ記憶部５６ｂに設定できる。その一例としては、出勤時・昼食時・退勤時などのピーク時等には、各号機エレベータ１０〜３０は頻繁に稼働し、昼間はスマートグリッド内で管理する消費電力の時間的変化が激しく、それに素早く応答する必要がある。そのため、タイマー部５６ｃを動作させる所定時間は短時間に設定する。   The predetermined time for operating the timer unit 56c can be arbitrarily set in advance in the setting data storage unit 56b. As an example, during peak hours such as at work, lunch, and retirement, each elevator 10-30 operates frequently, and the power consumption managed in the smart grid during the daytime is drastically changed. You need to respond quickly. Therefore, the predetermined time for operating the timer unit 56c is set to a short time.

一方、閑散時には、エレベータの稼働率が下がり、また、夜間はスマートグリッド内で管理する消費電力の時間的変化は緩やかであり、素早く応答する必要がないので、タイマー部５６ｃを動作させる所定時間は長時間に設定する。   On the other hand, when it is quiet, the operation rate of the elevator is lowered, and the time change of the power consumption managed in the smart grid is moderate at night, and it is not necessary to respond quickly, so the predetermined time for operating the timer unit 56c is Set to a long time.

さらに、照明減光解除手段５４Ｃは、メイン処理に戻ってエレベータシステムの総消費電力Ｐ０´と電力制限解除信号Ｐ１´との大小関係を比較し、かご照明の減光解除を行った効果を評価する（Ｓ５６）。   Further, the illumination dimming canceling means 54C returns to the main processing, compares the magnitude relation between the total power consumption P0 ′ of the elevator system and the power limit canceling signal P1 ′, and evaluates the effect of canceling the deluminance cancellation of the car lighting. (S56).

すなわち、照明減光解除手段５４Ｃは、総消費電力Ｐ０´と電力制限解除信号Ｐ１´との大小関係を比較した結果、総消費電力Ｐ０´が大きければ、処理継続（Ｓ７２）を条件にステップＳ５２に戻って同様の処理を繰り返し実行する。電力制限信号Ｐ１´が大きければ、号機運転制限解除手段５４Ｄを実行する。   That is, if the total power consumption P0 ′ is large as a result of comparing the magnitude relationship between the total power consumption P0 ′ and the power limit cancellation signal P1 ′, the illumination dimming cancellation unit 54C performs the processing continuation (S72) as a condition in step S52. Return to the above and repeat the same process. If the power restriction signal P1 ′ is large, the unit operation restriction release means 54D is executed.

号機運転制限解除手段５４Ｄは、前述する電力制限項目の１つである加速度・定格速度の解除処理を実行する。すなわち、１号機エレベータ１０から順次解除処理を行うために、補助記憶装置５６に設定されるカウンタメモリ（図示せず）にｎ＝１を設定し（Ｓ５７）、かつ、設定データ記憶部５６ｂに予め設定される加速度・定格速度に関する電力制限解除データ（例えば通常の定格状態に戻すか、現在よりも５％電力増加させる）に基づき、１号機エレベータ１０の巻上機１４の加速度・定格速度を引き上げた後（Ｓ５８）、電力測定を行う（Ｓ５９）。電力測定処理は、図５（ｂ）に示す通りであって、ここではその重複する説明は省略する。   Unit operation restriction release means 54D executes acceleration / rated speed release processing, which is one of the power restriction items described above. That is, in order to sequentially perform the release processing from the first elevator 10, n = 1 is set in a counter memory (not shown) set in the auxiliary storage device 56 (S 57), and the setting data storage unit 56 b is previously set. Increase the acceleration and rated speed of the hoisting machine 14 of the first elevator 10 based on the power restriction cancellation data (for example, return to the normal rated state or increase the power by 5% from the current level) regarding the set acceleration and rated speed. After that, power measurement is performed (S59). The power measurement process is as shown in FIG. 5B, and redundant description thereof is omitted here.

号機運転制限解除手段５４Ｄは、電力測定処理を行った後、加速度・定格速度の制限解除を行った効果を評価するために、再び電力制限解除信号Ｐ１´とエレベータシステムの総消費電力Ｐ０´との大小関係を比較する（Ｓ６０）。   The unit operation restriction release means 54D performs the power measurement process and then evaluates the power restriction release signal P1 ′ and the total power consumption P0 ′ of the elevator system again in order to evaluate the effect of releasing the restriction on acceleration / rated speed. Are compared (S60).

ここで、エレベータシステムの総消費電力Ｐ０´が大きければ、処理継続（Ｓ７２）を条件にステップＳ２に戻って同様の処理を繰り返し実行する。一方、電力制限解除信号Ｐ１が大きければ、全号機エレベータ１０〜３０の加速度・定格速度の制限解除の実施終了か否かを判断し（Ｓ６１）、未だ全号機制限解除終了でない場合にはカウンタメモリを＋１インクリメントし（Ｓ６２）、次の２号機エレベータ２０の巻上機１４の加速度・定格速度を引き上げた後（Ｓ５８）、同様の処理を繰り返すことで消費電力の低下を図る（Ｓ５８〜Ｓ６２）。   Here, if the total power consumption P0 ′ of the elevator system is large, the process returns to step S2 on condition that the process is continued (S72), and the same process is repeated. On the other hand, if the power restriction release signal P1 is large, it is determined whether or not the restriction cancellation of the acceleration / rated speed of all the elevators 10 to 30 has been completed (S61). Is incremented by +1 (S62), and the acceleration and rated speed of the hoisting machine 14 of the next No. 2 elevator 20 are increased (S58), and the same processing is repeated to reduce power consumption (S58 to S62). .

号機運転制限解除手段５４Ｄは、Ｎ（Ｎ＝３）号機３０まで加速度・定格速度の制限解除処理を行っても、電力制限解除信号Ｐ１´が総消費電力Ｐ０´より大きければ、次の電力制限項目である運転方向の制限を解除する電力制限解除データを伴う運転指令信号４２ａ，４２ｂ，４２ｃを送出し（Ｓ６３）、図５（ｂ）に示す電力測定を行う（Ｓ６４）。   The unit operation restriction release means 54D performs the next restriction on the power if the power restriction release signal P1 ′ is greater than the total power consumption P0 ′ even if the acceleration / rated speed restriction release processing is performed up to N (N = 3) No. 30. The operation command signals 42a, 42b, and 42c accompanied by the power restriction release data for releasing the restriction on the driving direction as an item are sent (S63), and the power measurement shown in FIG. 5B is performed (S64).

そして、号機運転制限解除手段５４Ｄは、電力測定を行った後にメイン処理に戻り、運転方向の制限解除を行った効果を評価するために、再び電力制限解除信号Ｐ１´とエレベータシステムの総消費電力Ｐ０´との大小関係を比較する（Ｓ６５）。ここで、総消費電力Ｐ０´が大きければ、処理継続（Ｓ７２）を条件にステップＳ５２に戻って同様の処理を繰り返し実行する。   Then, the unit operation restriction release means 54D returns to the main process after performing the power measurement, and again evaluates the effect of releasing the restriction on the driving direction and the power restriction release signal P1 ′ and the total power consumption of the elevator system. The magnitude relationship with P0 ′ is compared (S65). If the total power consumption P0 ′ is large, the process returns to step S52 on condition that the process is continued (S72), and the same process is repeatedly executed.

一方、電力制限解除信号Ｐ１´が大きければ、予め定める次の電力制限項目である例えば運転休止の制限の解除する電力制限解除データを伴う運転指令信号４２ａ，４２ｂ，４２ｃを送出し、１号機エレベータ１０から順次制限の解除処理を行う。   On the other hand, if the power limit release signal P1 ′ is large, the operation command signals 42a, 42b, and 42c accompanied by power limit release data for canceling the restriction on operation stop, which are predetermined next power limit items, are transmitted, and the first elevator The restriction release processing is performed sequentially from 10.

号機運転制限解除手段５４Ｄは、補助記憶装置５６に設定されるカウンタメモリ（図示せず）にｎ＝１を設定し（Ｓ５７）、かつ、設定データ記憶部５６ｂに予め設定される運転休止制限の制限解除に基づき、１号機エレベータ１０の運転復帰を行った後（Ｓ６７）、図５（ｂ）に示す一連の電力測定処理を実行する（Ｓ６８）。   The unit operation restriction release means 54D sets n = 1 in a counter memory (not shown) set in the auxiliary storage device 56 (S57), and sets the operation suspension restriction preset in the setting data storage unit 56b. After the operation of the first elevator 10 is restored based on the restriction release (S67), a series of power measurement processes shown in FIG. 5B is executed (S68).

そして、再び電力制限解除信号Ｐ１´とエレベータシステムの総消費電力Ｐ０´との大小関係を比較し（Ｓ６９）、総消費電力Ｐ０´が大きければ、処理継続（Ｓ７２）を条件にステップＳ５２に戻って同様の処理を繰り返し、電力制限解除信号Ｐ１´が大きければ、次の２号機エレベータ２０の運転復帰を果す。運転休止制限の解除処理はＮ（Ｎ＝３）号機エレベータ３０まで行って終了する（Ｓ７３）。   Then, the magnitude relationship between the power limit release signal P1 ′ and the total power consumption P0 ′ of the elevator system is compared again (S69). If the total power consumption P0 ′ is large, the process returns to step S52 on condition that the process is continued (S72). The same processing is repeated, and if the power limit release signal P1 ′ is large, the next unit 2 elevator 20 is returned to operation. The cancellation processing of the operation stop restriction is performed up to the N (N = 3) elevator 30 (S73).

従って、以上のような電力制限解除処理に関する実施形態によれば、スマートグリッド内の電力消費減少または発電力増加等によって電力供給に余裕がある場合は、乗りかごの照明の減光、電動機の加速度・定格速度の制限、運転方向の制限、運転休止の制限等を順次段階的に解除していくので、中央監視制御装置６０からの電力制限解除信号Ｐ１´に確実に応えることができ、ひいてはスマートグリッドに十分適用可能なエレベータシステムを実現できる。   Therefore, according to the embodiment related to the power restriction release processing as described above, when there is a margin in power supply due to a decrease in power consumption or an increase in generated power in the smart grid, the lighting of the car is dimmed, the motor acceleration is increased.・ Since the rated speed limit, the driving direction limit, the operation stop limit, etc. are canceled in stages, the power limit cancellation signal P1 ′ from the central supervisory control device 60 can be surely responded. An elevator system applicable to the grid can be realized.

また、中央監視制御装置６０から電力制限解除信号Ｐ１´の指令を受けたとき、予め定める電力制限項目を段階的に選択し電力制限を解除し、電力制限解除信号Ｐ１´と全号機エレベータの総消費電力Ｐ０´との差が徐々に小さくなるようにフィードバック制御による運転を実施するので、全号機エレベータの総消費電力Ｐ０を徐々に増加させつつ復帰させることができ、適切に複数号機エレベータ１０〜３０の電力制限解除による運転制御を実施できる。   In addition, when receiving the command of the power limit release signal P1 ′ from the central supervisory control device 60, the predetermined power limit items are selected step by step to release the power limit, and the power limit release signal P1 ′ and the total elevator of all the elevators Since the operation by feedback control is performed so that the difference from the power consumption P0 ′ is gradually reduced, the total power consumption P0 of all the elevators can be gradually increased and returned, and the plurality of elevators Operation control by canceling 30 power restrictions can be implemented.
