Description

本発明は、列車の回生制動による回生電力を吸収する回生電力吸収システムに適用される回生制動制御装置に関する。   The present invention relates to a regenerative braking control device applied to a regenerative power absorption system that absorbs regenerative power generated by regenerative braking of a train.

列車にブレーキをかける場合の一つとして回生制動がある。これは、ブレーキをかける際には電車を駆動する電動機を発電機として作用させ、発電された電力を回生電力として取り出すものである。回生制動により得られた回生電力は、回生電力吸収システムに供給され消費される。   One of the ways to brake a train is regenerative braking. In this case, when the brake is applied, an electric motor that drives a train is made to act as a generator, and the generated electric power is taken out as regenerative electric power. The regenerative power obtained by regenerative braking is supplied to the regenerative power absorption system and consumed.

例えば、電鉄き電系統における回生電力吸収システムは、回生電力をインバータを用いて交流に変換し、動力負荷系統の動力負荷等に供給することで吸収させる。そして、動力負荷等で吸収できない余分な電力は、電力吸収装置にて消費させ吸収するようにしている。なお、回生電力は常に供給されるわけではないので、この動力負荷には、受電系統から交流電力が供給されるようになっており、通常時は受電系統から電力が供給され回生制動時に回生電力を消費することになる。   For example, a regenerative power absorption system in an electric railway power system absorbs regenerative power by converting it into alternating current using an inverter and supplying it to a power load or the like of a power load system. Then, excess power that cannot be absorbed by a power load or the like is consumed and absorbed by the power absorbing device. Since regenerative power is not always supplied, AC power is supplied to the power load from the power receiving system. Normally, power is supplied from the power receiving system, and regenerative power is supplied during regenerative braking. Will be consumed.

このような回生電力吸収システムにおいては、電力吸収装置は動力負荷等で吸収できない余分な電力が検出されて初めて投入されるので、余分な電力の吸収が間に合わないことがある。そこで、き電系統の列車から回生制動によるブレーキ信号を入力し、ブレーキ信号が入力された状態のときに動力負荷の電力量が規定値以下（軽負荷）であるときは電力吸収装置を動力負荷系統に接続するようにしたものがある（例えば特許文献１参照）。
特開２００３−２０５７７３号公報（図１、図２） In such a regenerative power absorption system, since the power absorption device is turned on only after the excess power that cannot be absorbed by the power load or the like is detected, the excess power may not be absorbed in time. Therefore, when the brake signal by regenerative braking is input from the train of the feeder system, and the amount of power of the power load is less than the specified value (light load) when the brake signal is input, the power absorber is connected to the power load. Some are connected to a system (see, for example, Patent Document 1).
Japanese Patent Laying-Open No. 2003-205773 (FIGS. 1 and 2)

しかしながら、電力吸収装置が吸収する電力量が適切でない場合には、エネルギーの無駄使いとなったり、余分な回生電力が受電点へ戻ろうとし受電系統に逆供給する恐れがある。電力吸収装置で吸収する電力量が多い場合には、回生電力が供給されているにもかかわらず、受電系統から電力を受電しなければならないことになる。また、電力吸収装置で吸収する電力量が少ない場合には回生電力が余剰となり受電系統に逆供給され、回生電力は歪んだ波形の電力であるので受電系統に多大の悪影響を与える。   However, if the amount of power absorbed by the power absorbing device is not appropriate, energy may be wasted or excess regenerative power may return to the power receiving point and be supplied back to the power receiving system. When the amount of power absorbed by the power absorbing device is large, the power must be received from the power receiving system even though regenerative power is supplied. Further, when the amount of power absorbed by the power absorption device is small, the regenerative power is surplus and is supplied back to the power receiving system. Since the regenerative power is distorted waveform power, it greatly affects the power receiving system.

本発明の目的は、迅速に回生電力の発生を検出し電力損失を最小限に抑制しつつ、列車ブレーキの効きを確保し、しかも歪んだ波形の回生電力を受電系統に逆供給させない回生制動制御装置を提供することである。   The purpose of the present invention is to quickly detect the occurrence of regenerative power and minimize power loss, ensure the effectiveness of train braking, and regenerative braking control that does not reversely supply distorted waveform regenerative power to the power receiving system Is to provide a device.

本発明の回生制動制御装置は、き電系統の電流およびき電系統の電圧に基づいて回生される電力量を計測する回生電力量計測部と、前記き電系統の回生電力を動力負荷に供給する動力負荷系統の動力負荷電流および動力負荷電圧に基づいて動力負荷電力を計測する動力負荷電力量計測部と、前記き電系統の列車から回生制動によるブレーキ信号を入力するブレーキ信号入力部と、前記回生電力量計測部で計測された回生電力量が前記動力負荷電力量計測部で計測された動力負荷電力量より大きいとき、または前記ブレーキ信号入力部にブレーキ信号が入力された状態のときに前記動力負荷電力量計測部で検出された負荷電力量が規定値以下であるときは電力吸収装置を前記動力負荷系統に接続する電力吸収装置投入判定部と、前記回生電力量計測部で計測された回生電力量と前記動力負荷電力量計測部で計測された動力負荷電力量との差に基づいて電力吸収装置の整定値を演算し前記電力吸収装置に出力する電力吸収整定値演算部とを備えたことを特徴とする。   A regenerative braking control device according to the present invention includes a regenerative electric energy measuring unit that measures the amount of electric power regenerated based on a current of a feeding system and a voltage of the feeding system, and supplies the regenerative power of the feeding system to a power load. A power load energy measuring unit that measures power load power based on a power load current and a power load voltage of the power load system, a brake signal input unit that inputs a brake signal by regenerative braking from the train of the feeding system, When the regenerative power amount measured by the regenerative power amount measuring unit is larger than the power load power amount measured by the power load power amount measuring unit, or when a brake signal is input to the brake signal input unit When the load power amount detected by the power load power amount measurement unit is equal to or less than a specified value, a power absorption device input determination unit that connects a power absorber to the power load system, and the regenerative power amount A power absorption settling that calculates a set value of the power absorption device based on a difference between the regenerative electric energy measured by the measurement unit and the power load electric energy measured by the power load power measurement unit and outputs the calculated value to the power absorption device And a value calculation unit.

本発明によれば、列車を回生失効させることなく回生電力を適正に吸収することができるので、列車ブレーキの効力を確保し、乱れた波形の電力を受電点へ逆供給することなく、電力損失を必要最小限に抑えることができる。   According to the present invention, the regenerative power can be properly absorbed without regenerating and invalidating the train, so that the power of the train brake can be ensured and the power loss can be achieved without reversely supplying the distorted waveform power to the power receiving point. Can be minimized.

列車のブレーキ信号または回生電力が発生したことの検出により、電力吸収装置を投入し、回生電力量が動力負荷系統の動力負荷側で吸収できない電力量の場合は、回生電力量および動力負荷電力量に基づいて余分な電力量のみを電力吸収装置にて消費する。つまり、回生失効させることなく、回生電力を吸収できるように働かせる。   When the train's brake signal or regenerative power is detected, the power absorption device is turned on, and if the regenerative power cannot be absorbed on the power load side of the power load system, the regenerative power and power load power Based on the above, only the extra power is consumed by the power absorbing device. In other words, it works so that regenerative power can be absorbed without causing regeneration to expire.

図１は本発明の実施例１に係る回生制動制御装置１１を回生電力吸収システムに適用した場合のシステム構成図である。列車１２のき電系統１３には直流電力が供給されている。すなわち、受電系統１４から供給される交流電圧を変圧器１５で変圧しコンバータ１６で直流に変換してき電系統１３に供給する。   FIG. 1 is a system configuration diagram when the regenerative braking control device 11 according to the first embodiment of the present invention is applied to a regenerative power absorption system. DC power is supplied to the feeding system 13 of the train 12. That is, the AC voltage supplied from the power receiving system 14 is transformed by the transformer 15, converted to DC by the converter 16, and supplied to the power system 13.

また、列車１２の回生制動時の回生電力はインバータ１７を介して交流に変換され、変圧器１８を介して動力負荷等が接続された動力動力負荷系統１９に供給される。動力負荷系統１９には遮断器２０を介して電力吸収装置２１が接続され、回生制動時の余分な回生電力を吸収する。また、回生電力は常に供給されるわけではないので、動力負荷系統１９の動力負荷等には、受電系統１４から変圧器２２を介して交流電力が供給されるになっており、通常時は受電系統１４から電力が供給される。そして、回生制動時に回生電力を消費することになる。   Further, the regenerative electric power at the time of regenerative braking of the train 12 is converted into alternating current via the inverter 17 and supplied to the power / power load system 19 to which a power load and the like are connected via the transformer 18. A power absorption device 21 is connected to the power load system 19 via a circuit breaker 20 to absorb excess regenerative power during regenerative braking. In addition, since regenerative power is not always supplied, AC power is supplied from the power receiving system 14 to the power load of the power load system 19 via the transformer 22. Electric power is supplied from the grid 14. And regenerative electric power is consumed at the time of regenerative braking.

き電区内での列車１２からの回生制動時のブレーキ信号ＢＫは、変電所に設置された回生制動制御装置１１に入力される。この列車１２のブレーキ信号ＢＫは、例えば無線により直接的に、または指令所の遠隔制御装置（遠制装置）を経由して回生制動制御装置１１に入力される。   The brake signal BK at the time of regenerative braking from the train 12 in the feeder line is input to the regenerative braking control device 11 installed at the substation.

The regenerative braking control device 11 calculates the regenerative power amount based on the feed system current ID and the feed system voltage VD, and calculates the power load power amount based on the power load current IA and the power load voltage VA. When the train load signal BK is input and the power load power amount is less than the specified value, or when the regenerative power amount is larger than the power load power amount, the circuit breaker 20 is turned on to The absorber 21 is connected to the power load system, and the set value of the power absorber 21 is calculated based on the difference between the regenerative power amount and the power load power amount and output to the power absorber 21. The power absorption device 21 absorbs the power amount of the set value.

The brake signal BK of the train is input to the brake signal input unit 23 of the regenerative braking control device 11 and input to the power absorption device input determination unit 24. On the other hand, the feeding system current ID of the feeding system 13 is input to the feeding current input unit 25, converted into numerical data by the feeding current input unit 25, and input to the direction determination unit 26 and the regenerative energy measuring unit 27. The Similarly, the feeding system voltage VD of the feeding system 13 is input to the feeding voltage input unit 28, converted into numerical data by the feeding voltage input unit 28, and input to the direction determination unit 26 and the regenerative energy measuring unit 27.

方向判別部２６は、き電電流入力部２５からのき電系統電流ＩＤおよびき電電圧入力部２８からのき電系統電圧ＶＤに基づいて、き電系統電流ＩＤの方向を判別するものであり、そのき電系統電流ＩＤの方向は電力吸収装置投入判定部２４に入力される。なお、き電系統電流ＩＤがインバータ１７の方向に流れているときは回生運転である。回生電力量計測部２７は、き電電流入力部２５からのき電系統電流ＩＤおよびき電電圧入力部２８からのき電系統電圧ＶＤに基づいて、き電系統１３の回生電力量を計測するものであり、その計測された回生電力量は電力吸収装置投入判定部２４および電力吸収整定値演算部２９に入力される。   The direction discriminating unit 26 discriminates the direction of the feeding system current ID based on the feeding system current ID from the feeding current input unit 25 and the feeding system voltage VD from the feeding voltage input unit 28. The direction of the power grid current ID is input to the power absorption device input determination unit 24. When the feeding system current ID flows in the direction of the inverter 17, the regenerative operation is performed. The regenerative electric energy measuring unit 27 measures the regenerative electric energy of the feeding system 13 based on the feeding system current ID from the feeding current input unit 25 and the feeding system voltage VD from the feeding voltage input unit 28. The measured amount of regenerative power is input to the power absorption device input determination unit 24 and the power absorption set value calculation unit 29.

一方、動力負荷系統１９の動力負荷電流ＩＡは動力負荷電流入力部３０に入力され、数値データに変換されて動力負荷電力量計測部３１に入力される。同様に、動力負荷系統１９の動力負荷電圧ＶＡは動力負荷電圧入力部３２に入力され、数値データに変換されて動力負荷電力量計測部３１に入力される。動力負荷電力量計測部３１は、動力負荷電流入力部３０からの動力負荷電流ＩＡおよび動力負荷電圧入力部３２からの動力負荷電圧ＶＡに基づいて動力負荷電力量を計測するものであり、計測された動力負荷系統の動力負荷電力量は、電力吸収装置投入判定部２４および電力吸収整定値演算部２９に入力される。   On the other hand, the power load current IA of the power load system 19 is input to the power load current input unit 30, converted into numerical data, and input to the power load energy measuring unit 31. Similarly, the power load voltage VA of the power load system 19 is input to the power load voltage input unit 32, converted into numerical data, and input to the power load electric energy measuring unit 31. The power load power amount measuring unit 31 measures the power load power amount based on the power load current IA from the power load current input unit 30 and the power load voltage VA from the power load voltage input unit 32, and is measured. The power load power amount of the power load system is input to the power absorption device input determination unit 24 and the power absorption set value calculation unit 29.

電力吸収装置投入判定部２４は、回生電力量計測部２７で計測された回生電力量が動力負荷電力量計測部３１で計測された動力負荷電力量より大きいとき、またはブレーキ信号入力部２３にブレーキ信号が入力された状態のときに動力負荷電力量計測部３１で検出された負荷電力量が規定値以下であるときは、電力吸収装置を動力負荷系統に接続するための遮断器２０を投入する。   When the regenerative power amount measured by the regenerative power amount measuring unit 27 is larger than the power load power amount measured by the power load power amount measuring unit 31 or when the regenerative power amount determining unit 24 determines whether the regenerative power amount measuring unit 27 When the load power amount detected by the power load power amount measuring unit 31 is not more than a specified value when the signal is input, the circuit breaker 20 for connecting the power absorbing device to the power load system is turned on. .

The settling value of 21 is calculated and output to the power absorber 21. The power absorbing device 21 absorbs the regenerative electric energy based on the set value. That is, when the regenerative power cannot be consumed on the power load system 19 side, the power absorbing device 21 absorbs the power that cannot be consumed.
