【0009】 本発明によれば、回生運転時において電力変換装置は、運行管理装置から遠隔で送信される所定の判断結果に基づいて、制御系の安定性が優先されるべき場合は制御安定性を重視した第1の制御パタンを、回生エネルギーを多く発生させることができる場合は回生エネルギーを重視した第2の制御パタンを用いて電動機を制御する。この最適な制御により、従来の制御安定性と回生エネルギーの大きさのトレードオフを改善し、制御系の安定性を向上しつつ、より大きな回生エネルギーを得ることができる。

Abstract
To provide a railway system that can obtain greater regenerative energy while improving the stability of a control system.SOLUTION: In a railway system, an operation management device 20 receives vehicle information about the operation status of a railway vehicle 3 sent from a vehicle control device 11, performs prescribed determination processing based on the vehicle information, and sends the determination result to the vehicle control device 11. The power conversion device 10 has a control pattern that emphasizes the control stability during regenerative operation and a control pattern that emphasizes the regenerative energy obtained during regenerative operation. The vehicle control device 11 selects a control pattern based on the determination result sent from the operation management device 20. The power conversion device 10 controls an electric motor 5 using one of the control patterns selected by the vehicle control device 11.SELECTED DRAWING: Figure 1
