Description

本発明は、鉄道車両の電動機に対して架線と蓄電装置とから給電を行う鉄道車両の蓄電装置制御方法に関する。   The present invention relates to a railway vehicle power storage device control method for supplying power from an overhead line and a power storage device to an electric motor of a rail vehicle.

蓄電装置を備えた鉄道車両では、架線からの給電によりインバータを介して交流電動機を駆動するとともに、車両に搭載した蓄電装置からインバータを介して電動機に電力を供給するようにしている。   In a railway vehicle equipped with a power storage device, an AC motor is driven via an inverter by feeding from an overhead line, and power is supplied to the motor via the inverter from a power storage device mounted on the vehicle.

しかしながら、従来の鉄道車両の蓄電装置制御方法では、分散配置された蓄電装置間で充電動作および放電動作の動作協調をとっていないため、分散配置された蓄電装置は効率よく充放電できていない。また、蓄電装置の蓄電器の種類が異なる場合や、同種の蓄電器を使用していてもその定格や特性が異なる場合は蓄電器が充放電できない。   However, in the conventional railway vehicle power storage device control method, since the operation coordination of the charging operation and the discharge operation is not performed between the distributed power storage devices, the distributed power storage devices cannot be charged and discharged efficiently. Further, when the type of the storage battery of the power storage device is different, or when the rating and characteristics are different even if the same type of storage battery is used, the storage battery cannot be charged / discharged.

本発明の目的は、種類の異なる蓄電器や蓄電器の定格や特性が異なる場合であっても、蓄電装置を効率よく充放電することができる鉄道車両の蓄電装置制御方法を提供することである。   An object of the present invention is to provide a railway vehicle power storage device control method capable of efficiently charging and discharging a power storage device even when different types of power storage devices and power storage devices have different ratings and characteristics.

本発明の鉄道車両の蓄電装置制御方法は、複数の車両を連結して構成する鉄道車両の少なくとも２つ以上の車両に蓄電器を備えた蓄電装置を搭載し、複数の蓄電装置間で情報を通信し、その情報に基づいて蓄電装置の放電動作もしくは充電動作を制御することを特徴とする。   According to the power storage device control method for a railway vehicle of the present invention, a power storage device including a power storage device is mounted on at least two or more vehicles of a railway vehicle configured by connecting a plurality of vehicles, and information is communicated between the plurality of power storage devices. The discharge operation or the charge operation of the power storage device is controlled based on the information.

本発明によれば、種類の異なる蓄電器や蓄電器の定格や特性が異なる場合であっても、蓄電装置を効率よく充放電することができる。   According to the present invention, it is possible to efficiently charge and discharge the power storage device even when the different types of capacitors and the ratings and characteristics of the capacitors are different.

（第１の実施の形態）
図１は本発明の第１の実施の形態に係わる鉄道車両の蓄電装置制御方法を適用した鉄道車両１１の構成図である。図１では、モータ車１２ａとトレーラ車１２ｂとの２両の車両１２を連結したものを示している。モータ車１２ａには集電装置１３が設けられ、集電装置１３から得られた直流電力は直流線１４を介してインバータ１５及び蓄電装置１６ａに供給される。インバータ１５は直流電力を交流電力に変換し、インバータ１５で変換された交流電力は交流線１７を介して車輪１８を駆動する交流モータ１９に供給される。一方、トレーラ車１２ｂは、連結装置２０でモータ車１２ａと連結され、モータ１９やインバータ１５を搭載していないが蓄電装置１６ｂを搭載しており、モータ車１２ａから直流線１４を介して蓄電装置１６ｂに直流電力を蓄積する。また、モータ車１２ａの蓄電装置１６ａとトレーラ車１２ｂの蓄電装置１６ｂとは通信線２１で接続されており、これらの蓄電装置１６ａ、１６ｂとの間で情報を通信するように構成されている。 (First embodiment)
FIG. 1 is a configuration diagram of a railway vehicle 11 to which the railway vehicle power storage device control method according to the first embodiment of the present invention is applied. In FIG. 1, a motor vehicle 12a and a trailer vehicle 12b are connected to each other. The motor vehicle 12 a is provided with a current collector 13, and DC power obtained from the current collector 13 is supplied to an inverter 15 and a power storage device 16 a via a DC line 14. The inverter 15 converts DC power into AC power, and the AC power converted by the inverter 15 is supplied to an AC motor 19 that drives the wheel 18 via an AC line 17. On the other hand, the trailer vehicle 12b is connected to the motor vehicle 12a by the connecting device 20 and is not equipped with the motor 19 or the inverter 15, but is equipped with the power storage device 16b. DC power is stored in 16b. The power storage device 16a of the motor vehicle 12a and the power storage device 16b of the trailer vehicle 12b are connected by a communication line 21, and are configured to communicate information with the power storage devices 16a and 16b.

すなわち、鉄道車両１１は複数の車両１２ａ、１２ｂを連結装置２０で接続して構成される。集電装置１３は外部の給電装置から直流電力の供給を受け、その直流電力を信号線１４を介してインバータ１５に入力する。インバータ１５はモータ１９を駆動するために可変交流可変周波数の交流電力に変換する。インバータ１５から出力された交流電力は交流線１７を介してモータ１９へと送られ、モータ１９を駆動することでモータ１９と接続された車輪１８を回転させて車両は走行する。   That is, the railway vehicle 11 is configured by connecting a plurality of vehicles 12 a and 12 b with the connecting device 20. The current collector 13 receives supply of DC power from an external power supply device, and inputs the DC power to the inverter 15 via the signal line 14. The inverter 15 converts the AC power into variable AC variable frequency AC power to drive the motor 19. The AC power output from the inverter 15 is sent to the motor 19 via the AC line 17, and the vehicle travels by driving the motor 19 to rotate the wheels 18 connected to the motor 19.

蓄電装置１６ａは他の蓄電装置１６ｂ及びインバータ１５と直流線１４で接続され、蓄電装置１６ａ、１６ｂが充放電する電力の受け渡しを行う。また分散配置された蓄電装置１６ａ、１６ｂ間は通信線２１で接続され、予め蓄電装置１６ａ、１６ｂが持つ固有情報や蓄電装置１６ａ、１６ｂで管理している情報を蓄電装置１６ａ、１６ｂ間で相互に通信する。   The power storage device 16a is connected to the other power storage device 16b and the inverter 15 through the DC line 14, and transfers power to be charged and discharged by the power storage devices 16a and 16b. In addition, the power storage devices 16a and 16b arranged in a distributed manner are connected by a communication line 21, and specific information held in advance by the power storage devices 16a and 16b and information managed by the power storage devices 16a and 16b are mutually connected between the power storage devices 16a and 16b. To communicate.

図２は、本発明の第１の実施の形態における蓄電装置１６の第１の実施例を示す構成図である。図２において、蓄電装置１６は、電力を蓄電する蓄電器２２、蓄電器２２に電力を充放電する充放電装置２３、入出力端子間に設けられた直流コンデンサ２４、各種制御を行う制御回路２５とから構成され、充放電装置２３は、リアクトル２６と２個の半導体素子２７ａ、２７ｂとで構成されている。   FIG. 2 is a configuration diagram illustrating a first example of the power storage device 16 according to the first embodiment of the present invention. In FIG. 2, the power storage device 16 includes a power storage device 22 that stores power, a charge / discharge device 23 that charges and discharges power to the power storage device 22, a DC capacitor 24 provided between input and output terminals, and a control circuit 25 that performs various controls. The charging / discharging device 23 includes a reactor 26 and two semiconductor elements 27a and 27b.

蓄電装置１６の制御回路２５は通信線２１に接続され、外部装置（他の蓄電装置１６）との通信機能を持ち通信を行う。すなわち、制御回路２５は、充放電装置２３の２個の半導体素子２７ａ、２７ｂをオン・オフ制御してして蓄電器２２を充放電を制御するとともに、蓄電装置１６の情報も管理する。この場合、通信機能を用いて、蓄電装置１６は自己の蓄電器２２の情報だけでなく、分散配置された他の蓄電装置１６の情報も管理・監視する。これにより、分散配置された全体の蓄電装置１６ａ、１６ｂの状態を考慮して効率よく自己の蓄電装置を充放電できるようになる。   The control circuit 25 of the power storage device 16 is connected to the communication line 21 and has a communication function with an external device (another power storage device 16) to perform communication. That is, the control circuit 25 controls on / off of the two semiconductor elements 27a and 27b of the charging / discharging device 23 to control charging / discharging of the battery 22, and also manages information on the power storage device 16. In this case, using the communication function, the power storage device 16 manages and monitors not only the information of its own power storage device 22 but also the information of other power storage devices 16 arranged in a distributed manner. Thereby, it becomes possible to efficiently charge and discharge the own power storage device in consideration of the state of the entire power storage devices 16a and 16b arranged in a distributed manner.

図３は、制御回路２５に格納される蓄電器２２の管理情報２８の説明図である。管理情報２８は蓄電装置１６の制御回路２５で管理され、蓄電器２２の蓄電種別や容量、定格電圧や最大電流など、充放電装置２３が蓄電器２２を充放電するための情報がデータ化されている。   FIG. 3 is an explanatory diagram of the management information 28 of the battery 22 stored in the control circuit 25. The management information 28 is managed by the control circuit 25 of the power storage device 16, and information for the charge / discharge device 23 to charge / discharge the capacitor 22 such as the power storage type, capacity, rated voltage, and maximum current of the power storage device 22 is converted into data. .

分散配置された蓄電装置１６にとっては、他の蓄電装置１６の管理情報が入手できると、他の蓄電装置１６は大電流対応型蓄電装置であるから自己の蓄電装置１６では電流を絞った充放電動作にするとか、他の蓄電装置１６は内部抵抗が小さいから、繰返しの運転は他の蓄電装置１６にまかせて自己の蓄電装置１６は温度上昇が生じない範囲に繰返し使用数を抑制するとかいった蓄電器２２に対する充放電方法の最適化ができるようになる。   For the power storage devices 16 that are arranged in a distributed manner, when the management information of the other power storage devices 16 is available, the other power storage devices 16 are high-current compatible power storage devices, so that their own power storage devices 16 charge and discharge with reduced current. Since the other power storage devices 16 have a low internal resistance, the repetitive operation is left to the other power storage devices 16 so that the self power storage device 16 suppresses the number of repeated uses within a range where the temperature does not increase. In addition, the charge / discharge method for the storage battery 22 can be optimized.

これにより、蓄電器２２の蓄電種別が異なっている場合や、蓄電装置１６の定格や特性が異なる場合でも、蓄電装置１６間で通信を行うことで効率よく蓄電装置１６の蓄電器２２の充放電をすることができる。また、同一の蓄電種別、同一の定格の蓄電器２２であっても蓄電装置１６を効率よく充放電できることは言うまでもない。   Thereby, even when the power storage type of the power storage device 22 is different or when the rating and characteristics of the power storage device 16 are different, the power storage device 16 is efficiently charged and discharged by performing communication between the power storage devices 16. be able to. Further, it goes without saying that the power storage device 16 can be charged and discharged efficiently even with the same power storage type 22 and the same rated power storage device 22.

図４は、本発明の第１の実施の形態における蓄電装置１６の第２の実施例を示す構成図である。図２に示した第１の実施例に対し、蓄電器２２の電圧を検出する電圧検出器２９が追加して設けられている。   FIG. 4 is a configuration diagram illustrating a second example of the power storage device 16 according to the first embodiment of the present invention. In addition to the first embodiment shown in FIG. 2, a voltage detector 29 for detecting the voltage of the battery 22 is additionally provided.

電圧検出器２９で検出された蓄電器２２の電圧は制御回路２５に入力され、制御回路２５は、電圧検出器２９で検出された蓄電器２２の電圧情報を分散配置した蓄電装置１６間で通信する。蓄電器２２の電圧は蓄電器２２が満充電状態や空の状態など蓄電器２２のエネルギー残量に関する情報を持っているので、蓄電装置１６間で通信することで、自己の蓄電器１６と他の蓄電器１６の電圧状態が分かり、この電圧状態に基づいて自己の蓄電器２２を充電すべきか、または放電すべきかという選択が自己の蓄電装置１６で制御できるようになる。これにより、分散配置された蓄電装置１６間で協調を図り、効率よく蓄電装置１６を充電もしくは放電できる。   The voltage of the battery 22 detected by the voltage detector 29 is input to the control circuit 25, and the control circuit 25 communicates between the power storage devices 16 in which the voltage information of the battery 22 detected by the voltage detector 29 is distributed. Since the voltage of the capacitor 22 has information on the remaining amount of energy of the capacitor 22 such as the fully charged state and the empty state, the communication between the power storage devices 16 allows communication between the own capacitor 16 and other capacitors 16. The voltage state is known, and the selection of whether the battery 22 should be charged or discharged based on the voltage state can be controlled by the battery device 16. Thereby, cooperation can be achieved between the power storage devices 16 that are distributed, and the power storage devices 16 can be charged or discharged efficiently.

図５は、本発明の第１の実施の形態における蓄電装置１６の第３の実施例を示す構成図である。図２に示した第１の実施例に対し、蓄電器２２の充放電電流を検出する電流検出器３０が追加して設けられている。   FIG. 5 is a configuration diagram illustrating a third example of the power storage device 16 according to the first embodiment of the present invention. In addition to the first embodiment shown in FIG. 2, a current detector 30 for detecting the charging / discharging current of the battery 22 is additionally provided.

電流検出器３０で検出された蓄電器２２の充放電電流は制御回路２５に入力され、制御回路２５は、電流検出器３０で検出された蓄電器２２の充放電電流情報を分散配置した蓄電装置１６間で通信する。これにより、自己の蓄電装置１６にて他の蓄電装置１６における充放電状態が把握できるようになり、必要に応じて自己の蓄電装置１６の充放電電流を制御し、全体として効率よく蓄電装置１６を充電もしくは放電できるようになる。   The charging / discharging current of the battery 22 detected by the current detector 30 is input to the control circuit 25, and the control circuit 25 distributes the charging / discharging current information of the battery 22 detected by the current detector 30 between the power storage devices 16. Communicate with. As a result, the own power storage device 16 can grasp the charge / discharge state in the other power storage device 16, and the charge / discharge current of the own power storage device 16 is controlled as necessary, thereby efficiently efficiently as a whole. Can be charged or discharged.

図６は、本発明の第１の実施の形態における蓄電装置１６の第４の実施例を示す構成図である。図２に示した第１の実施例に対し、蓄電器２２の温度を検出する温度検出器３１が追加して設けられている。温度検出器３１で検出された蓄電器２２の温度は制御回路２５に入力され、制御回路２５は、温度検出器３１で検出された蓄電器２２の温度情報を分散配置した蓄電装置１６間で通信する。   FIG. 6 is a configuration diagram illustrating a fourth example of the power storage device 16 according to the first embodiment of the present invention. In addition to the first embodiment shown in FIG. 2, a temperature detector 31 for detecting the temperature of the battery 22 is additionally provided. The temperature of the battery 22 detected by the temperature detector 31 is input to the control circuit 25, and the control circuit 25 communicates between the power storage devices 16 in which the temperature information of the battery 22 detected by the temperature detector 31 is distributed.

これにより、自己の蓄電装置１６にて他の蓄電装置１６の蓄電器２２の温度が把握できるようになり、他の蓄電装置１６の蓄電器２２にて温度が過大となった場合には、自己の蓄電装置１６の充放電電流を増大させることで温度が過大となった蓄電器２２の負担を軽減することができる。従って、蓄電器２２の温度バランスを整えて、効率よく蓄電装置１６を充電もしくは放電できるようになる。   As a result, the temperature of the battery 22 of the other power storage device 16 can be grasped by the self power storage device 16, and when the temperature of the power storage device 22 of the other power storage device 16 becomes excessive, Increasing the charge / discharge current of the device 16 can reduce the burden on the capacitor 22 whose temperature is excessive. Therefore, the temperature balance of the battery 22 is adjusted, and the power storage device 16 can be charged or discharged efficiently.

図７は、本発明の第１の実施の形態における蓄電装置１６の第５の実施例を示す構成図である。図２に示した第１の実施例に対し、蓄電器２２の電圧を検出する電圧検出器２９及び蓄電器２２の充放電電流を検出する電流検出器３０が追加して設けられている。   FIG. 7 is a configuration diagram illustrating a fifth example of the power storage device 16 according to the first embodiment of the present invention. A voltage detector 29 for detecting the voltage of the battery 22 and a current detector 30 for detecting the charge / discharge current of the battery 22 are additionally provided in the first embodiment shown in FIG.

電圧検出器２９で検出された蓄電器２２の電圧及び電流検出器３０で検出された蓄電器２２の電流は、制御回路２５に入力され、制御回路２５により蓄電器２２に蓄電される電力を計算する。つまり、蓄電器２２のエネルギー残量情報が算出される。この蓄電器２２のエネルギー残量情報を分散配置した蓄電装置１６間で通信する。   The voltage of the battery 22 detected by the voltage detector 29 and the current of the battery 22 detected by the current detector 30 are input to the control circuit 25, and the power stored in the battery 22 is calculated by the control circuit 25. That is, the remaining energy information of the battery 22 is calculated. The remaining energy information of the battery 22 is communicated among the power storage devices 16 that are distributed.

すなわち、蓄電器２２の充放電電流を電流検出器３０で検出し、制御回路２５で電流検出器３０の出力信号を積算して電流積算値を求める。また、電圧検出器２９から得た電圧信号を基に、電圧信号が満充電状態の場合は電流積算値を１００％にセットし、電圧信号が空の状態の場合は電流積算値を０％にリセットする。この電流積算値は蓄電器２２のエネルギー残量情報として使用することができ、このエネルギー残量情報を他の蓄電装置１６との間で通信する。   That is, the charge / discharge current of the battery 22 is detected by the current detector 30 and the output signal of the current detector 30 is integrated by the control circuit 25 to obtain the current integrated value. Also, based on the voltage signal obtained from the voltage detector 29, the integrated current value is set to 100% when the voltage signal is fully charged, and the integrated current value is set to 0% when the voltage signal is empty. Reset. This integrated current value can be used as remaining energy information of the battery 22, and this remaining energy information is communicated with other power storage devices 16.

これにより、分散配置された蓄電装置１６間で、エネルギー残量を監視しながら充放電することができ、エネルギーを適切に配分して効率よく蓄電装置１６を充電もしくは放電できるようになる。   Accordingly, charging and discharging can be performed while monitoring the remaining amount of energy between the power storage devices 16 arranged in a distributed manner, and the power storage device 16 can be efficiently charged or discharged by appropriately allocating energy.

図８は、制御回路２５に格納される蓄電器２２の動作履歴３２の説明図である。動作履歴３２は蓄電装置１６の制御回路２５で管理され、蓄電器２２の充放電動作回数や動作時間、また電圧と電流を積算して得た積算電力といった動作履歴をデータとして保持している。この動作履歴を分散配置された蓄電装置１６間で通信することで、相互の蓄電装置１６が使用頻度や劣化状態を把握することができる。   FIG. 8 is an explanatory diagram of the operation history 32 of the battery 22 stored in the control circuit 25. The operation history 32 is managed by the control circuit 25 of the power storage device 16, and holds operation history such as the number of charging / discharging operations and the operation time of the battery 22 and the integrated power obtained by integrating the voltage and current as data. By communicating this operation history among the power storage devices 16 that are distributed, the mutual power storage devices 16 can grasp the usage frequency and the deterioration state.

これにより、他の蓄電装置１６の使用頻度よりも自己の蓄電装置１６の使用頻度が少なければ、自己の蓄電装置１６を優先的に充放電することで鉄道車両の中で蓄電装置１６の使用頻度を整えて効率よく蓄電装置を使用することができるようになる。   As a result, if the frequency of use of the power storage device 16 is less than the frequency of use of the other power storage devices 16, the frequency of use of the power storage device 16 in the railway vehicle is preferentially charged and discharged. This makes it possible to use the power storage device efficiently.

図９は、制御回路２５に格納される蓄電器２２の故障情報３３の説明図である。故障情報３３は蓄電装置１６の制御回路２５で管理され、蓄電装置１６は自己の蓄電装置１６で発生した故障状態を故障情報３３としてデータ保持する。この故障情報３３を他の蓄電装置１６と通信することで、蓄電装置１６が相互に故障状態を把握することができる。   FIG. 9 is an explanatory diagram of the failure information 33 of the battery 22 stored in the control circuit 25. The failure information 33 is managed by the control circuit 25 of the power storage device 16, and the power storage device 16 holds the failure state that has occurred in its own power storage device 16 as failure information 33. By communicating this failure information 33 with other power storage devices 16, the power storage devices 16 can grasp the failure state of each other.

これにより、他の蓄電装置１６にて充放電できない故障状態であれば、充放電可能な蓄電装置１６が充放電電流を増加させ、故障した蓄電装置１６の充放電電流分を負担するなど、故障情報３３に応じて鉄道車両内で効率よく蓄電装置１６を運用することができる。   As a result, if the failure state cannot be charged / discharged by another power storage device 16, the charge / discharge power storage device 16 increases the charge / discharge current and bears the charge / discharge current of the failed power storage device 16. The power storage device 16 can be efficiently operated in the railway vehicle according to the information 33.

図１０は、本発明の第１の実施の形態における蓄電装置１６の第６の実施例を示す構成図である。図５に示した第３の実施例に対し、蓄電装置１６の入出力端子間の直流コンデンサ２４の直流電圧を検出する直流電圧検出器３４が追加して設けられている。   FIG. 10 is a configuration diagram illustrating a sixth example of the power storage device 16 according to the first embodiment of the present invention. In contrast to the third embodiment shown in FIG. 5, a DC voltage detector 34 for detecting the DC voltage of the DC capacitor 24 between the input and output terminals of the power storage device 16 is additionally provided.

直流電圧検出器３４で検出された蓄電装置１６の入出力端子間の直流コンデンサ２４の直流電圧は制御回路２５に入力され、制御回路２５は、この蓄電装置１６の入出力端子間の直流コンデンサ２４の直流電圧を分散配置した蓄電装置１６間で通信する。そして、各々の蓄電装置１６での充電動作の偏りを小さくする。   The DC voltage of the DC capacitor 24 between the input and output terminals of the power storage device 16 detected by the DC voltage detector 34 is input to the control circuit 25, and the control circuit 25 detects the DC capacitor 24 between the input and output terminals of the power storage device 16. Are communicated between the power storage devices 16 in which the DC voltage is distributed. And the bias of the charging operation in each power storage device 16 is reduced.

すなわち、直流電圧検出器３４から得る電圧検出値は、分散配置された蓄電装置１６間で検出誤差等の理由で異なっていると、電圧検出値が小さい情報を持つ蓄電装置１６は先に充電動作を行い、電圧検出値が大きい情報を持つ蓄電装置１６は充電動作を行わないといった偏りが生ずる可能性がある。そこで、分散配置された蓄電装置１６が電圧検出値を通信することで直流電圧情報を共通化して蓄電装置間の充放電動作の協調を図る。   That is, if the voltage detection value obtained from the DC voltage detector 34 differs among the distributed storage devices 16 due to a detection error or the like, the storage device 16 having information with a small voltage detection value is charged first. The power storage device 16 having information with a large voltage detection value may be biased such that the charging operation is not performed. Therefore, the distributed power storage devices 16 communicate voltage detection values so that the DC voltage information is shared and the charge / discharge operations between the power storage devices are coordinated.

図１１は、制御回路２５の充電動作均一化制御の制御ブロック図である。図１１において、直流電圧検出器３４で検出された直流電圧は直流電圧検出値演算手段３５に入力される。直流電圧検出値演算手段３５は、直流電圧検出器３４で検出された直流電圧を通信線２１を介して他の蓄電装置１６に送信するとともに、他の蓄電装置１６からの直流電圧を受信して直流電圧を共通化する。共通化された直流電圧は、電圧指令値設定器３６に設定された電圧指令値と比較器３７で比較される。   FIG. 11 is a control block diagram of the charging operation equalization control of the control circuit 25. In FIG. 11, the DC voltage detected by the DC voltage detector 34 is input to the DC voltage detection value calculation means 35. The DC voltage detection value calculation means 35 transmits the DC voltage detected by the DC voltage detector 34 to the other power storage device 16 via the communication line 21 and receives the DC voltage from the other power storage device 16. Standardize DC voltage. The common DC voltage is compared with the voltage command value set in the voltage command value setting unit 36 by the comparator 37.

電圧指令値は、直流電圧に対して例えば１８００Ｖを越えたら蓄電装置１６を充電し、１４００Ｖを下回ったら蓄電装置１６を放電するといった充放電動作情報である。電圧指令値から電圧検出値を比較器３７で引算し、その出力信号を電圧制御回路３８に入力する。電圧制御回路３８は蓄電器２２の電流指令値を演算する。   The voltage command value is charge / discharge operation information such as charging the power storage device 16 when the direct current voltage exceeds 1800 V, for example, and discharging the power storage device 16 when the voltage falls below 1400 V. The voltage detection value is subtracted from the voltage command value by the comparator 37, and the output signal is input to the voltage control circuit 38. The voltage control circuit 38 calculates a current command value for the battery 22.

一方、電流検出器３０で検出された電流検出値は電流検出値記憶部３９に記憶されている。そして、比較器４０は、電圧制御回路３８の出力である電流指令値から電流検出値記憶部３９に記憶された電流検出値を引算する。その出力信号を電流制御回路４１に入力して電流信号を演算し、この電流信号をＰＷＭ制御回路４２に入力してＰＷＭ信号を算出して、ゲート回路４３にＰＷＭ信号を入力してゲート信号を生成する。このように、分散配置された蓄電装置１６が電圧検出値を通信することで直流電圧情報を共通化して蓄電装置間の充放電動作の協調を図る。これにより、分散配置された蓄電装置間で動作タイミングを整えることができ、効率よく充放電動作を行うことができる。   On the other hand, the current detection value detected by the current detector 30 is stored in the current detection value storage unit 39. Then, the comparator 40 subtracts the current detection value stored in the current detection value storage unit 39 from the current command value that is the output of the voltage control circuit 38. The output signal is input to the current control circuit 41 to calculate the current signal, the current signal is input to the PWM control circuit 42 to calculate the PWM signal, and the PWM signal is input to the gate circuit 43 to obtain the gate signal. Generate. In this way, the distributed power storage devices 16 communicate voltage detection values to share DC voltage information and to coordinate charge / discharge operations between the power storage devices. As a result, the operation timing can be adjusted between the power storage devices that are distributed and the charge / discharge operation can be performed efficiently.

図１２は、本発明の第１の実施の形態における蓄電装置１６の第７の実施例を示す構成図である。図２に示した第１の実施例に対し、蓄電装置１６の温度を検出する温度検出器４４が設けられている。   FIG. 12 is a configuration diagram illustrating a seventh example of the power storage device 16 according to the first embodiment of the present invention. In contrast to the first embodiment shown in FIG. 2, a temperature detector 44 for detecting the temperature of the power storage device 16 is provided.

温度検出器４４は蓄電装置１６の筐体の温度を検出し、温度検出器４４で検出された蓄電装置１６の温度は制御回路２５に入力される。制御回路２５は、温度検出器４４で検出された蓄電装置１６の温度情報を分散配置した蓄電装置１６間で通信する。すなわち、蓄電装置１６の筐体の温度情報を通信することで、蓄電装置１６の筐体の温度上昇が大きい蓄電装置１６の充放電動作を軽減して、筐体温度に余裕のある蓄電装置１６の充放電動作を増やすことで、筐体温度の上昇した蓄電装置１６の温度上昇を抑制することができる。   The temperature detector 44 detects the temperature of the housing of the power storage device 16, and the temperature of the power storage device 16 detected by the temperature detector 44 is input to the control circuit 25. The control circuit 25 communicates between the power storage devices 16 in which the temperature information of the power storage devices 16 detected by the temperature detector 44 is distributed. That is, by communicating temperature information of the housing of the power storage device 16, the charge / discharge operation of the power storage device 16 in which the temperature rise of the housing of the power storage device 16 is large is reduced, and the power storage device 16 having a sufficient housing temperature. By increasing the charging / discharging operation, it is possible to suppress the temperature rise of the power storage device 16 whose housing temperature has risen.

これにより、筐体温度の過度な上昇を抑えて効率よく蓄電装置１６を充放電することができる。また特性の異なる蓄電装置１６の場合は、その蓄電装置１６の動作環境に適した筐体温度を維持でき、鉄道車両全体で効率よく最適な充放電動作を行うことが可能となる。   Thereby, it is possible to efficiently charge and discharge the power storage device 16 while suppressing an excessive increase in the housing temperature. Further, in the case of the power storage device 16 having different characteristics, the housing temperature suitable for the operating environment of the power storage device 16 can be maintained, and the optimal charge / discharge operation can be performed efficiently in the entire railway vehicle.

また、蓄電装置１６の制御回路２５は充放電装置２３を制御するために、蓄電器２２の充放電動作に関する情報を常時監視しているが、充放電動作に関する情報、例えば、充放電動作の指令値や動作タイミングを分散配置された蓄電装置１６に通信することで、蓄電装置１６間で動作協調を図ることも可能である。   Further, in order to control the charging / discharging device 23, the control circuit 25 of the power storage device 16 constantly monitors information related to the charging / discharging operation of the capacitor 22, but information related to the charging / discharging operation, for example, a command value for the charging / discharging operation. It is also possible to achieve operation coordination among the power storage devices 16 by communicating the operation timing with the power storage devices 16 that are distributed.

また、通信する情報は同時に複数の情報（管理情報、電圧情報、充放電電流情報、蓄電器の温度情報、エネルギー残量情報、動作履歴、故障情報、直流電圧情報、蓄電装置の温度情報、充放電動作情報など）を通信するようにすることで、蓄電装置１６間での協調動作は精度の高いものになる。これにより、分散配置された蓄電装置１６間での動作を精度向上することができ、また複雑な協調条件であっても蓄電装置が動作できるようになる。よって分散配置された蓄電装置を効率よく充放電することが可能となる。   In addition, information to be communicated includes a plurality of information (management information, voltage information, charge / discharge current information, battery temperature information, energy remaining information, operation history, failure information, DC voltage information, power storage device temperature information, charge / discharge) By communicating the operation information and the like, the cooperative operation between the power storage devices 16 becomes highly accurate. As a result, it is possible to improve the accuracy of the operation between the power storage devices 16 arranged in a distributed manner, and the power storage device can operate even under complicated cooperative conditions. Therefore, it is possible to efficiently charge and discharge the power storage devices arranged in a distributed manner.

第１の実施の形態によれば、蓄電装置１６間で情報を通信するので、種類の異なる蓄電器２２や、蓄電器２２の定格や特性が異なる場合であっても、鉄道車両全体の蓄電装置１６を効率よく充放電することができる。   According to the first embodiment, since information is communicated between the power storage devices 16, the power storage devices 16 of the entire railway vehicle can be connected even when different types of power storage devices 22 and the ratings and characteristics of the power storage devices 22 are different. Charge and discharge can be performed efficiently.
