PROBLEM TO BE SOLVED: To provide a station power supply capable of efficiently utilizing excess regenerative power of an electric motor vehicle regardless of variation of feeding voltage of a substation.SOLUTION: A regeneration start voltage threshold Vset which is higher than feeding voltages VssA, VssB of substations 200a, 200b for supplying power to a transformation zone, is set as a voltage threshold for starting supply of excess regenerative power to a station load 4, and when applied voltage to a station power source 100 becomes higher than the regeneration start voltage threshold Vset, power is supplied to the station load 4.
【課題】変電所の送り出し電圧の変動に依らず、電気車の余剰回生電力を有効活用することができる駅舎電源装置を得ること。【解決手段】駅負荷4に余剰回生電力の供給を開始する電圧閾値として、変電区間に電力を供給する変電所200a,200bの送り出し電圧VssA,VssBよりも大きい回生開始電圧閾値Vsetを設定し、駅舎電源装置100への印加電圧が回生開始電圧閾値Vsetを上回った場合に、駅負荷4に電力供給を行うようにした。【選択図】図1
