ALTERNATING CURRENT FEEDING SYSTEM

To provide an alternating current feeding system for effectively utilizing regenerative electric power by improving an introduction facility use rate without interfering with a power converter and a power storage device.SOLUTION: An alternating current feeding system 14 provided with a power converter 5 is used as power over adjacent first and second power feeding lines 2a, 2b and includes first and second power sources 4a, 4b for feeding power to first and second vehicle 1a, 1b through the first and second power feeding lines 2a, 2b, a power storage device 6 connected between the second power source 4b and the second power feeding line 2b, and a control device 7 for generating a request power amount 11b to the power converter 5 and a charge/discharge command 10 to the power storage device 6. The control device 7 generates the request power amount 11b and the charge/discharge command 10 on the basis of prescribed observation information and a control condition, the observation information is reception power 8b from the second power source 4b and charge/discharge power 9 of the power storage device 6, and the control condition prioritizes the power converter 5 over the power storage device 6 as distribution of regenerative electric power.SELECTED DRAWING: Figure 1 【課題】電力変換器と蓄電装置を干渉させず、導入設備利用率を向上し、回生電力を有効活用させる交流き電システムを提供する。【解決手段】 隣接する第一、第二のき電線２ａ，２ｂに跨って電力融通する電力変換器５を備えた交流き電システム１４であって、第一、第二のき電線２ａ，２ｂを介して第一、第二の車両１ａ，１ｂにき電する第一、第二の電源４ａ，４ｂと、第二の電源４ｂと第二のき電線２ｂの間に接続された蓄電装置６と、電力変換器５に対する要求電力量１１ｂと蓄電装置６に対する充放電指令１０とを生成する制御装置７と、を備え、制御装置７は、要求電力量１１ｂ及び充放電指令１０を、所定の観測情報及び制御条件に基づいて生成し、観測情報は、第二の電源４ｂからの受電電力８ｂと、蓄電装置６の充放電電力９であり、制御条件は回生電力の配分として蓄電装置６よりも電力変換器５を優先する。【選択図】図１
