To solve the problem of line voltage drop due to line resistance of a tail cord as a building becomes taller and the tail cord becomes longer since power is supplied from a storage battery on a control panel side to a door control unit via the tail cord.SOLUTION: An elevator operation system during power failure that switches from commercial power to storage batteries when the commercial power fails, and opens the doors to rescue passengers after driving the car that was stopped between floors to the nearest floor, comprises: a power conversion unit that converts the electric power supplied to the car via a tail cord from the storage battery installed in a control panel that controls the lifting and lowering of the car; a door opening/closing control unit that is connected to the power conversion unit and performs car door opening/closing control; and car equipment other than the door opening/closing control unit that is connected to the power conversion unit via opening/closing means. The door opening/closing control unit opens the opening/closing means for a predetermined period of time, including the start of door opening during power failure operation.SELECTED DRAWING: Figure 3

    【課題】 制御盤側の蓄電池からテールコードを経由しドア制御装置に電力を供給しているため、建物が高層化しテールコードが長くなると、テールコードの線路抵抗による線路電圧降下が発生する。【解決手段】エレベータの停電時運転システムは、商用電源が停電すると商用電源から蓄電池に切り替えて、階間に停止したかごを最寄り階まで運転後、戸開して乗客を救出するエレベータの停電時運転システムにおいて、かごを昇降制御する制御盤に設置された蓄電池からテールコードを介してかご側に供給される電力を変換する電力変換部と、電力変換部と接続されかごの戸開閉制御を行う戸開閉制御部と、電力変換部と開閉手段を介して接続される、戸開閉制御部以外のかご機器と、を備え、戸開閉制御部は、停電運転時の戸開開始時を含む所定期間、開閉手段を開放することを特徴とする。【選択図】図3
