Description

電力系統に接続する基地局装置を制御するシステム、基地局装置、基地局装置制御装置およびその充電制御方法SYSTEM FOR CONTROLLING BASE STATION DEVICE CONNECTED TO POWER SYSTEM, BASE STATION DEVICE, BASE STATION DEVICE CONTROLLER, AND CHARGE CONTROL METHOD THEREOF
　本発明は、電力系統に接続する蓄電システムとその制御方法に関する。 The present invention relates to a storage system connected to a power system and a control method thereof.
　無線通信端末を用いて、いつでも安定した通信を行うためには、この無線通信端末と通信を行う基地局装置に、常に電力を供給しなければならない。しかしながら、停電が発生すると、基地局装置への電力の供給が途絶えてしまい、通信が切断されてしまい、送電が復帰するまでには相当の時間を要することがある。特に電力供給が安定していない国や地域では、日常的な地域での停電や、限られた時間のみ電力供給がされるなど電力系統から常時電力を供給されるとは限らない。そこで、電力系統以外の電源が必要となる。 In order to perform stable communication at any time using a wireless communication terminal, it is necessary to always supply power to a base station apparatus that communicates with this wireless communication terminal. However, when a power failure occurs, the power supply to the base station device is cut off, communication is cut off, and it may take a considerable amount of time to restore power transmission. In particular, in countries and regions where power supply is not stable, power is not always supplied from the power system, such as blackouts in daily areas and power supplied only for a limited time. Therefore, power supplies other than the power system are required.
　ディーゼル発電機による電源が一般的であるが、燃料切れの恐れや燃料補充の必要性、環境への悪影響がある。また、電力系統より原動費が高いこともあり、電力系統から充電する蓄電池を使用することが考えられる。 Although diesel power supplies are common, there is a risk of running out of fuel, the need for refueling, and adverse effects on the environment. In addition, since the driving cost is higher than the power system, it is conceivable to use a storage battery to be charged from the power system.
　しかしながら、多数の基地局装置の蓄電池を一度に充電すると電力系統の電力供給が不安定になり、電力系統の停電をまねく恐れがある。 However, if the storage batteries of many base station apparatuses are charged at one time, the power supply of the power system becomes unstable, which may lead to a power failure of the power system.

　本発明は、電力系統に接続された複数の基地局装置を制御するシステムにおける基地局装置に併設された蓄電池の充電制御方法であって、電力系統の電力供給情報と負荷設備の電力需要情報と蓄電池の蓄電情報（蓄電量、電池温度）に基づいて蓄電池の充電制御を行うことを特徴とする。 The present invention is a charge control method of a storage battery provided in parallel to a base station device in a system for controlling a plurality of base station devices connected to a power system, which includes power supply information of a power system and power demand information of a load facility. It is characterized in that charge control of the storage battery is performed based on storage information (storage amount, battery temperature) of the storage battery.

　《第一の実施の形態》
　図１は、本発明の電力系統に接続された基地局装置と蓄電池を示した図である。発電所１００から変電所１１０を経由して電力系統１０３～１０８から基地局装置１０２に電力が供給される。 First Embodiment
FIG. 1 is a diagram showing a base station apparatus and a storage battery connected to the power system of the present invention. Electric power is supplied from the power plant 100 to the base station apparatus 102 from the power grids 103 to 108 via the substation 110.
　図２は、本発明の基地局装置１０２を示した図である。基地局装置１０２は、基地局装置制御装置１０１、負荷設備２０５、発電設備２０８を備える。基地局装置制御装置１０１は、電力状態検知部２０２と制御部２０３と蓄電池２０４（例えばＬｉイオン電池）を備える。発電設備２０８は必ずしも設けなくても良い。 FIG. 2 is a diagram showing a base station apparatus 102 of the present invention. The base station apparatus 102 includes a base station apparatus control device 101, a load facility 205, and a power generation facility 208. The base station control device 101 includes a power state detection unit 202, a control unit 203, and a storage battery 204 (for example, a lithium ion battery). The power generation facility 208 may not necessarily be provided.
　電力系統１０３～１０８は末端に向かって枝分かれしていくが、末端になるほど電力供給は不安定になり、電力系統１０３～１０８の各々に繋がる設備の電力使用量が多いほど電力供給は不安定になる。変電所で分離された電力系統１０３～１０８ごとに電力使用量が供給を上回ると停電する可能性が高いが、過大な負荷がかかると根幹の電力系統１０３への停電を引き起こすこともありうる。 The power systems 103 to 108 branch toward the end, but the power supply becomes unstable at the end, and the power supply becomes unstable as the power consumption of the facility connected to each of the power systems 103 to 108 increases. Become. If power consumption exceeds the supply for each of the power systems 103 to 108 separated at the substation, there is a high possibility that a power failure will occur, but an excessive load may cause a power failure to the power system 103 of the root.
　発電設備２０８が併設されており、発電設備２０８が太陽光発電設備の場合は、発電設備２０８から負荷設備２０５に電力供給し、発電量に余裕がある場合は蓄電池２０４へ充電を行う。 When the power generation facility 208 is provided side by side and the power generation facility 208 is a solar power generation facility, power is supplied from the power generation facility 208 to the load facility 205, and the storage battery 204 is charged if there is enough power generation.
　太陽光発電設備が無い場合あるいは、太陽光発電設備があっても天候により発電出来ない場合は、太陽光発電設備から電力の供給できない負荷設備２０５に電力系統１０３～１０８のいずれかから、電力供給し、さらに蓄電池２０４の蓄電量等の蓄電情報から蓄電池２０４に充電が必要と判断した場合、蓄電池２０４へ充電を行う。 If there is no solar power generation facility, or even if there is a solar power generation facility, electricity can not be generated due to the weather, power is supplied from any of the power grids 103 to 108 to the load facility 205 which can not supply power Furthermore, if it is determined from the storage information of the storage amount of the storage battery 204 and the like that the storage battery 204 needs to be charged, the storage battery 204 is charged.
　もし、停電した場合、制御部２０３は蓄電池２０４より電力を負荷設備２０５に供給して負荷設備２０５の稼動を継続させる。しかしながら蓄電池２０４の蓄電量が停電中に無くなる恐れがあるとき、制御部２０３は、負荷設備２０５を通常動作モードから低電力動作モードに移行することで、負荷設備２０５の停止を防止する。 If a power failure occurs, the control unit 203 supplies power from the storage battery 204 to the load facility 205 to continue the operation of the load facility 205. However, when there is a possibility that the storage amount of the storage battery 204 may be lost during a power failure, the control unit 203 shifts the load facility 205 from the normal operation mode to the low power operation mode to prevent the load facility 205 from stopping.
　停電し、さらに蓄電量が無い場合でも、発電設備２０８がそれらの条件に左右されないディーゼル発電等であれば、発電制御することで発電設備２０８を稼動し、負荷設備２０５の稼動を継続させることも可能となる。発電量に余裕があれば発電設備から蓄電池２０４への充電を開始してもよい。 Even if there is a power failure and there is no amount of stored electricity, if the power generation facility 208 is diesel power generation or the like which does not depend on those conditions, the power generation facility 208 is operated by power generation control to continue the operation of the load facility 205. It becomes possible. If there is a margin in the amount of power generation, charging of the storage battery 204 from the power generation facility may be started.
　発電設備２０８は、太陽光発電とディーゼル発電を併用しても良い。 The power generation facility 208 may use both solar power generation and diesel power generation.
　電力系統１０３～１０８のうち蓄電池２０４に接続されたいずれかの電力系統１０３～１０８から蓄電池２０４に充電する場合、通常、制御部２０３は基地局装置の負荷設備２０５に電力系統１０３～１０８から電力を供給するように制御する。また、制御部２０３は、蓄電池の蓄電量が低下すると蓄電池２０４に電力系統１０３～１０８から充電するよう制御する。ここで、蓄電池２０４は複数の充電速度を有する。本実施の形態においては、蓄電池２０４は、充電速度が異なる２つの充電モード（急速充電、通常充電）を有する。急速充電は通常充電よりも速い時間で充電できるが、電気使用量が多くなる。停電時に備えて、各基地局装置はできる限り急速充電を行うが、急速充電を複数の基地局装置で同時に行うと、全体の電気使用量が膨大になるため、電力系統１０３～１０８の電力供給そのものが不安定になり、電力系統１０３～１０８が停電しかねない。 When charging the storage battery 204 from any of the power grids 103 to 108 of the power grids 103 to 108 connected to the storage battery 204, the control unit 203 normally supplies power to the load equipment 205 of the base station apparatus from the power grids 103 to 108. Control to supply Further, control unit 203 controls storage battery 204 to be charged from power grids 103 to 108 when the storage amount of the storage battery is reduced. Here, the storage battery 204 has a plurality of charging rates. In the present embodiment, storage battery 204 has two charge modes (rapid charge, normal charge) having different charge rates. Although fast charging can be performed in a faster time than normal charging, it consumes more electricity. Although each base station device performs quick charging as much as possible in preparation for a power failure, if the rapid charging is simultaneously performed by a plurality of base station devices, the total amount of electricity used becomes enormous, so the power supply of the power grids 103 to 108 is supplied. That thing becomes unstable and may cause a power failure in the power systems 103-108.
　電力系統１０３～１０８の停電を避けるため、基地局装置制御装置１０１は電力系統１０３～１０８の電力状態情報（周波数、電圧、電流）を電力状態検知部２０２により検知する。電力供給状態から電力安定度が不安定な状況と判断すると、蓄電池２０４の充電を通常充電に変更、あるいは充電そのものを停止し充電待機とする充電制御を行う。ここで、電力安定度とは、系統電力の安定度合いを示す指標であり、変電所１１０からの電力供給量や、電力系統１０３～１０８に繋がる設備の電力使用量により変動する。電力安定度が悪化すると、末端の電力系統１０６～１０８から停電する可能性が高い。電力安定度がさらに悪化すると、根幹に向かう電力系統１０４，１０５も停電する可能性が高い。さらに悪化すると電力系統１０３～１０８全体が停電する可能性が高い。過大な負荷がかかると根幹の電力系統への停電を引き起こすこともありうる。 The base station control device 101 detects power state information (frequency, voltage, current) of the power grids 103 to 108 by the power state detection unit 202 in order to avoid a power failure of the power grids 103 to 108. If it is determined from the power supply state that the power stability is unstable, charge control is performed to change the charge of the storage battery 204 to normal charge or to stop the charge itself and to be in charge standby. Here, the power stability is an index indicating the degree of stability of the grid power, and fluctuates depending on the amount of power supplied from the substation 110 and the amount of power consumed by facilities connected to the power grids 103 to. When the power stability deteriorates, there is a high possibility that a power failure from the end power systems 106 to 108 will occur. If the power stability further deteriorates, there is a high possibility that the power grids 104 and 105 heading to the root will also lose power. If it gets worse further, there is a high possibility that the entire power grids 103 to 108 will fail. Excessive loading may cause a power outage to the underlying power system.
　具体的には、系統電力（電力系統１０３～１０８から供給される電力）の周波数、電圧、電流を監視することにより、電力系統の周波数、電圧、電流等の電力状態情報から電力安定度を判断する。周波数については系統電力の全体負荷が大きくなると、系統電力から供給される交流信号の周波数が低くなる。ゼロクロスカウンター等で周波数を検知し、所定の周波数よりも低くなった場合に、電力安定度が低いと判断できる。電圧監視は、系統電力から供給される電圧の低下を検知する。電流監視は系統電力から供給される電流の低下を検知する。電圧監視や電流監視は、周波数監視と比べて、簡易な構成で系統電力の電力安定度を検知することができる。また、系統電力の周波数、電圧、電流の値だけではなく、系統電力の周波数、電圧、電流の値の急激な変化を捉えることで、電力供給状態が不安定になること（すなわち、電力安定度の低下）も検知できる。 Specifically, by monitoring the frequency, voltage and current of the grid power (power supplied from the power grids 103 to 108), the power stability is judged from the power status information such as the power grid frequency, voltage and current. Do. As for the frequency, when the total load of the grid power increases, the frequency of the AC signal supplied from the grid power decreases. When the frequency is detected by a zero cross counter or the like and the frequency becomes lower than a predetermined frequency, it can be determined that the power stability is low. Voltage monitoring detects a drop in voltage supplied from the grid power. Current monitoring detects a drop in current supplied from the grid power. Voltage monitoring and current monitoring can detect the power stability of the grid power with a simple configuration as compared to frequency monitoring. In addition, the power supply state becomes unstable by capturing not only the grid power frequency, voltage, and current values, but also abrupt changes in grid power frequency, voltage, and current values (that is, power stability Can also be detected.
　そして、通常充電あるいは充電待機中の場合、電力供給状態が安定状態になった（すなわち、電力安定度が高くなった）と判断すれば、通常充電の場合、蓄電池２０４への急速充電へ復帰し、充電待機中の場合、急速充電か通常充電を再開する充電制御を行う。 Then, if it is determined that the power supply state has become stable (that is, the power stability has increased) in the normal charging or charging standby state, in the case of the normal charging, the battery 204 is returned to the rapid charging. When charging standby, perform charging control to resume quick charging or normal charging.
　なお、本実施例では一例として、通常充電の充電速度は、急速充電の充電速度の三分の一程度にするが、それに関わらず、どのような速度にしても構わない。電力供給状態に合わせて可変にしても良い。 In the present embodiment, as an example, the charging speed of normal charging is set to about one third of the charging speed of rapid charging, but any speed may be used regardless of that. It may be variable according to the power supply state.
　このように、電力系統の停電が発生する前に電力供給状態を監視しながら蓄電池への充電制御（充電速度の制御）を行うことで、図１のように、電力供給状態が不安定状態と判断すると、ある基地局装置は充電待機中になり、電力系統の電力安定度の低下を防ぐ。これにより、各基地局装置の基地局装置制御装置１０１は電力系統の停電を避けつつ、蓄電池への充電を行うことができる。 As described above, by performing charge control (control of the charge rate) to the storage battery while monitoring the power supply state before a power outage of the power system occurs, the power supply state becomes unstable as shown in FIG. If it judges, a base station apparatus will be in charge standby, and the fall of the power stability of electric power system is prevented. Thereby, the base station control device 101 of each base station can charge the storage battery while avoiding a power failure of the power system.
　図３は、本発明の別の基地局装置１３２を示した図である。図２の基地局装置制御装置１０１を基地局装置制御装置３０１に換えて、さらに負荷設備３０５の制御を行うものである。負荷設備３０５から消費電力量、通信量、重要度等の電力需要情報を制御部３０３に送る。蓄電池２０４への充電制御だけでは、電力系統の安定が不十分な場合には、基地局装置制御装置３０１の制御部３０３は負荷設備３０５を通常動作モードから低電力動作モードに移行することで、電力系統の停電を防止する。基地局装置の場合、例えば、負荷設備３０５の通信速度や通信エリアを制限することで、低電力動作モードへ移行し、消費電力を低減する。電力状態検知部２０２と蓄電池２０４は図２と同じでも異なっていてもよい。 FIG. 3 is a diagram showing another base station apparatus 132 of the present invention. The base station control device 101 of FIG. 2 is replaced with a base station control device 301 to control the load equipment 305 further. Power demand information such as power consumption, communication volume, and importance is sent from the load facility 305 to the control unit 303. When the stability of the power system is insufficient only with the charge control to the storage battery 204, the control unit 303 of the base station device control device 301 transfers the load equipment 305 from the normal operation mode to the low power operation mode, Prevent power outages. In the case of the base station apparatus, for example, by limiting the communication speed and communication area of the load equipment 305, the mode shifts to the low power operation mode to reduce power consumption. The power state detection unit 202 and the storage battery 204 may be the same as or different from FIG.
　これにより、系統電力が不安定な電力インフラの環境下において、電力状態情報、電力需要情報、蓄電情報を用いて停電を避けることでディーゼル発電への依存を低減しつつ、負荷設備３０５への安定給電が可能となる。 As a result, in an environment of power infrastructure with unstable system power, stability to the load facility 305 can be reduced while avoiding power failure by using power status information, power demand information, and storage information to avoid power failure. Power can be supplied.

FIG. 4 is a diagram showing a base station storage system of the present invention. Compared with the first embodiment, inter-base station control apparatus 401 controls inter-base station apparatuses.
　図５は、本発明の基地局装置間制御装置４０１を示した図である。基地局装置間制御装置４０１は、電力供給会社からの電力負荷情報や、計画送電情報（あるいは停電情報）等の電力供給情報を利用する系統監視部５０２と、後述する複数の基地局装置制御装置からの情報を受け取る受信部５０７と基地局装置制御装置への制御情報を送信する送信部５０６を備える。送受信は、無線であっても有線であっても、専用回線であっても共用回線であってもよい。制御部５０３は、電力供給会社からの電力負荷情報や、電力供給情報、複数の基地局装置制御装置からの情報から、各基地局装置の蓄電池の充電制御を行う制御情報を生成する。 FIG. 5 is a diagram showing an inter-base station controller 401 according to the present invention. The inter-base station apparatus control apparatus 401 includes a system monitoring unit 502 that uses power supply information such as power load information from a power supply company or planned power transmission information (or power failure information), and a plurality of base station apparatus control apparatuses described later. And a transmission unit 506 for transmitting control information to the base station control device. Transmission and reception may be wireless, wired, dedicated, or shared. The control unit 503 generates control information for performing charge control of the storage battery of each base station apparatus from the power load information from the power supply company, the power supply information, and the information from the plurality of base station apparatus control devices.
　図６は、本発明の基地局装置間制御装置４０１と通信する基地局装置１６２を示した図である。図３の基地局装置制御装置３０１に比べ、基地局装置１６２は送信部６０６、受信部６０７を備える。電力状態検知部２０２と蓄電池２０４と負荷設備３０５は図３と同じでも異なっていてもよい。発電設備２０８は必ずしも併設する必要は無く、発電設備２０８との送受信信号の図示は省略している。 FIG. 6 is a diagram showing a base station apparatus 162 in communication with the inter-base station apparatus control apparatus 401 of the present invention. The base station apparatus 162 includes a transmitting unit 606 and a receiving unit 607 as compared to the base station apparatus control device 301 in FIG. 3. The power state detection unit 202, the storage battery 204, and the load facility 305 may be the same as or different from FIG. The power generation facility 208 does not necessarily have to be provided side by side, and illustration of transmission and reception signals with the power generation facility 208 is omitted.
　電力系統に接続された各負荷設備３０５に電力使用状況（周波数、電圧、電流）をモニターする電力状態検知部２０２（例えば、スマートメーター）を設け、基地局装置間制御装置４０１は、基地局装置１６２の送信部６０６から電力状態情報を受信し、その情報に基づいて、系統電力全体の負荷状況を判断するようにしてもよい。 A power condition detection unit 202 (for example, a smart meter) for monitoring the power usage condition (frequency, voltage, current) is provided in each load facility 305 connected to the power system, and the inter-base station control device 401 The power state information may be received from the transmission unit 606 of 162, and the load state of the entire system power may be determined based on the information.
　制御部６０３は、電力状態検知部２０２の電力系統の周波数、電圧、電流等の電力状態情報や、蓄電池２０４の蓄電量等の蓄電情報、負荷設備３０５の消費電力量、通信量、重要度等の電力需要情報を送信部６０６により基地局装置間制御装置４０１に送信する。受信部６０７が受信した基地局装置間制御装置４０１からの制御情報に基づき、制御部６０３は、蓄電池２０４の充電制御を行う。 The control unit 603 is power state information such as the frequency, voltage, and current of the power system of the power state detection unit 202, storage information such as the storage amount of the storage battery 204, power consumption of the load facility 305, communication amount, importance, etc. The power demand information is transmitted to the inter-base station control device 401 by the transmission unit 606. The control unit 603 performs charge control of the storage battery 204 based on the control information from the inter-base station control device 401 received by the receiving unit 607.
　電力状態検知部２０２により電力供給が不安定になり、電力安定度が悪化したと判断したときは、基地局装置間制御装置４０１からの制御情報に優先して、蓄電池２０４の充電を急速充電から通常充電にする、あるいは、充電停止にしてもよい。 When it is determined by the power state detection unit 202 that the power supply has become unstable and the power stability has deteriorated, priority is given to control information from the inter-base station control device 401 to charge the storage battery 204 from quick charging. The normal charging may be performed or the charging may be stopped.
　あるいは、負荷設備３０５を通常動作モードから低電力動作モードに移行することで、電力系統の停電を防止する。基地局装置の場合、例えば、負荷設備３０５を通信速度や通信エリアを制限する低電力動作モードに移行することで消費電力を低減する。これにより電力系統への負荷をいち早く下げることができるので、電力系統の停電を避けることができる。蓄電池２０４と負荷設備３０５の制御を併用してもよい。 Alternatively, by shifting the load equipment 305 from the normal operation mode to the low power operation mode, power failure of the power system is prevented. In the case of the base station apparatus, for example, power consumption is reduced by shifting the load equipment 305 to a low power operation mode that limits the communication speed and communication area. As a result, the load on the power system can be reduced promptly, so that a power failure of the power system can be avoided. The control of the storage battery 204 and the load facility 305 may be used in combination.
　基地局装置間制御装置４０１の制御部５０３は、電力系統が停電しないように各基地局装置の蓄電池の充電制御を行うために、充電が必要な複数の基地局装置に対して充電可能な電力が見込めない場合、どの基地局装置の蓄電池を充電するか決定する必要がある。すなわち、充電優先度を基地局装置単位あるいは、複数の電力系統で構成される電力網全体の電力供給安定度を考慮した場合、電力系統単位で決定する。 The control unit 503 of the inter-base station control device 401 can charge the plurality of base station devices that need to be charged in order to perform charge control of the storage battery of each base station device so that the power system does not lose power. If it can not be expected, it is necessary to decide which base station apparatus's storage battery should be charged. That is, in consideration of the power supply stability of the entire power network configured of a base station unit or a plurality of power grids, the charging priority is determined on a power grid basis.
　優先度を決定するための情報としては、以下のようなものがある。 The information to determine the priority is as follows.
　１）蓄電池の蓄電量　・・・　残量が少ない蓄電池を優先する。 1) Storage capacity of storage battery · · · · · Priority is given to storage batteries with a small remaining amount.
　２）負荷設備の消費電力　・・・　例えば、基地局装置の場合は通信量など消費電力が大きい負荷設備を優先する。 2) Power consumption of load facility ··· For example, in the case of a base station apparatus, priority is given to a load facility with large power consumption such as communication volume.
　３）稼動残量　・・・　（１）蓄電池の蓄電量と（２）負荷設備の消費電力から算出される稼動時間の残量から優先度を決める。 3) Remaining operating capacity ... (1) Determine the priority from the remaining capacity of the storage battery and (2) the remaining operating time calculated from the power consumption of the load facility.
　４）温度　・・・　Ｌｉイオン電池は低温・高温時に充電効率が悪いため、不適当温度状態のＬｉイオン電池の蓄電池の優先度を下げる。 4) Temperature · · · Li-ion battery has poor charge efficiency at low temperature and high temperature, lower the priority of the battery of Li-ion batteries unsuitable temperature conditions.
　５）発電設備の状態　・・・　蓄電池が、系統電力と発電設備の切り替えが可能なハイブリッド方式の場合、発電設備の発電情報から優先度を決める。例えば、ディーゼル発電の場合は、ディーゼル燃料の残量が少ない蓄電池を優先する。太陽光発電の場合は発電量や天候などから優先度を決める。 5) State of power generation facility · · · · · · · If the storage battery is a hybrid system that can switch between grid power and power generation facility, determine the priority from the power generation information of the power generation facility. For example, in the case of diesel power generation, priority is given to a storage battery with a small amount of remaining diesel fuel. In the case of solar power generation, the priority is determined based on the amount of power generation and the weather.
　６）系統種別（Ｇｏｏｄ－Ｇｒｉｄ，　Ａｖｅｒａｇｅ－Ｇｒｉｄ，　Ｐｏｏｒ－Ｇｒｉｄ，　Ｏｆｆ－Ｇｒｉｄ等）　・・・　電力系統ごとの電力供給の安定性（例えば、一日当たりの平均電力供給時間）に関する情報から優先度を決める。例えば、電力供給が不安定（Ｐｏｏｒ－Ｇｒｉｄ）な地域を優先する。 6) System type (Good-Grid, Average-Grid, Poor-Grid, Off-Grid etc.) ・ ・ ・ Priority from information on stability of power supply per power system (eg average power supply time per day) Decide. For example, priority is given to areas where power supply is unstable (Poor-Grid).
　７）蓄電池の設置場所　・・・　電力系統上で隣接する基地局装置は同時に給電しないようにする。 7) Installation location of storage battery · · · · · Adjacent base station devices on the power system should not be powered at the same time.
　これらの情報を組み合わせて優先度を決定してもよい。 These pieces of information may be combined to determine the priority.
　以上のように基地局装置間制御装置が電力網あるいは、電力系統に接続された基地局装置を制御することで、電力系統の停電を避けつつ、より稼動が必要とされる基地局装置に接続された蓄電池への充電を行うことで、稼動停止を避けることができる。 As described above, the inter-base station apparatus control apparatus controls the power network or the base station apparatus connected to the power system to connect to a base station apparatus that requires more operation while avoiding a power outage of the power system. By charging the storage battery, operation stop can be avoided.
　基地局装置間制御装置と基地局装置制御装置の制御の役割は、一例であってこれに限らない。例えば、各基地局装置は一切制御内容を決定せず、基地局装置間制御装置から受信した信号のみで制御するようにしてもよい。 The control roles of the inter-base station apparatus control apparatus and the base station apparatus control apparatus are an example and not limited to this. For example, each base station apparatus may control only the signal received from the inter-base-station control apparatus without determining the control content at all.
　電力系統に接続された基地局装置への充電制御に利用可能であるが、電力系統に接続された稼動停止を避けたい設備についても応用可能である。 Although it can be used for charge control to a base station apparatus connected to the power system, it can be applied to equipment connected to the power system that wants to avoid an operation stop.
