【Abstract】 A simple and convenient circuit to achieve the coordination of substation protection and the out-going line protection of one-side substation(10(6)-35kV) with the power network is developed. Acceleration is operated before and after the three phase one--time reclose. The speed of fixing a breakdown is quickened, and reclose success rate and supply electricity are improved.更多还原
