摘　　要：分布式电源在电网中份额逐渐提高,发生故障后的重合闸技术能够保障电网运行可靠性。相比于三相重合闸技术,单相重合闸的可靠性、安全性更高。文章分析了分布式电源非全相运行时复合网络的电压、电流分量,分析重合闸时的电压、电流冲击。仿真结果表明:电压、电流分量符合分析结果,准确度高。The share of distributed power supply in the power grid is gradually increasing,and the reclosing technology after failure can ensure the utilization rate of distributed power supply.Compared with threephase reclosing technology,single-phase reclosing has higher reliability and safety.The voltage and current components of the composite network in the non-full phase operation of the distributed power supply and shock of voltage and current during reclosing were analyzed.The simulation results show that the voltage and current components agree with the analysis results in high accuracy.
