| 摘 要： | 含分布式电源的配电网一般为双电源或多电源供电系统,需要对其重合闸方式进行研究,以保证设备安全.以含分布式电源的解列重合闸为例,对系统侧电源重合于永久故障形成的冲击电流进行分析.从机理上讨论了无压检定和同步检定的在含分布式电源系统中的应用.通过仿真验证了无压检定和同步检定重合闸后电流变化过程,并求出分布式电源并网时冲击电流最小的最佳重合闸时间.

| Abstract: | Distribution networks with distributed generation always presents as dual-power or multi-power supply system,the reclosing mode needs to be researched to ensure the equipments safe.This paper establishes disconnected reclosing system with distributed generation,and analyzes the impulse current when the distribution system recloses with permanent fault.The application of no-voltage test reclosing and the synchronization test reclosing device in the distribution network with distributed generation is investigated.Simulation results verified the no-voltage test and synchronization test reclosing current change processes.The optimal reclosing time is suggested considering reclosing distributed generation with minimum impulse current. |

| Keywords: | distributed generation auto-reclosing distribution network optimal reclosing time impulse current |
