To provide an alternating current feeding system which is not mutually interfered with an existing power converter, and improves a utilization rate of regenerative power even when added with the power converter.SOLUTION: An alternating current feeding system of an electric railroad in which a plurality of power converters 104(i) and 104(ii) can interchange power such as regenerative power striding over feeding lines 102a, 102b and 102c alternating of different feeding sections includes a first power converter 104(i) that is connected to a first feeding line 102a and a second feeding line 102b and interchanges power therebetween, and a second power converter 104(ii) that is connected to the second feeding line and a third feeding line 102c and interchanges power therebetween, and gives a command value given to the first or second power converter on the basis of a difference between receiving power from a second power source 103b and interchange power from the other power converter different from own power converter.SELECTED DRAWING: Figure 1
【課題】電力変換器を追加しても既設の電力変換器に相互干渉させず、回生電力の活用率を向上させる交流き電システムを提供する。【解決手段】複数の電力変換器104(i)、104(ii)が、異なるき電区間のき電線102a、102b、102cを跨いで、回生電力等の電力融通可能な電気鉄道の交流き電システムであって、第1のき電線102aと第2のき電線102bに接続され、これらの間で電力を融通する第1の電力変換器104(i)と、第2のき電線と第3のき電線102cに接続され、これらの間で電力を融通する第2の電力変換器104(ii)と、を備え、第1又は第2の電力変換器に与える指令値を、第2の電源103bからの受電電力と自電力変換器とは異なるもう一方の電力変換器からの融通電力との差に基づいて与える。【選択図】図1
