車両の軽負荷回生制御を考慮した地上蓄電装置の充放電電流パターンの設計方法に関する一考察

摘要

The introduction of the waysaide energy strage device is considered as one of effective metods to reduce the light-load regenerative limitation status. However, experimental test resuls with actual vehicle runnig show that all the potential regenerative energy is not always absorbed by wayside energy storage device, due to the light-load regenerative limitation. In this paper, the absorbable regenrative energy is dipicted by the current control patterns of light-load regenerative control, charging current pattern of the wayside energy storage device and the distance between the renegerating vehicle and energy storage device. Then, in order to increase the energy-saving effect for the capacity of the wayside energy storage device, this paper provide a guide line how to set the current control patterns of light-load regenerative control system of the vehicle and the wayside energy storage device control system.%本稿では，閑散線区で行った地上蓄電装置の充放電試験結果に基づき，列車の軽負荷回生絞り込み制御が地上蓄電装置の充電制御に与える影響に着目し，回生車と地上蓄電装置との距離に応じて期待される回生電力がどのように変わるかを図を用いて示した。そして，地上蓄電装置充電制御の充電開始電圧は低く，充電電流立ち上がり角を大きく，列車の回生絞り込み制御においては，絞り込み開始電圧を絞り込み終端電圧に近づけるよう設定することで回生電力量の増加を見込むことができることを示した。
