摘　　要：随着分布式光伏电源在配电网中渗透率逐渐提高,在进行分布式光伏电源接入线路停电检修时断开系统电源,分布式光伏电源与负荷形成孤岛系统的可能性增大,严重威胁检修人员的人身安全。针对以上问题,从检修人员角度出发,分析了检修人员在线路进线端能够采取的接入负荷和模拟短路故障两种措施的可行性,检修人员在线路进线端接入容性负荷可以低成本、可靠地使线路中孤岛运行的分布式光伏电源退出运行,从而保障检修人员的人身安全。With the gradual increase of the penetration rate of distributed photovoltaic generation in the distribution network and in case of of disconnecting the system power supplyduring power outage maintenance of distribution network lines with distributed photovoltaic generation,the possibility of distributed photovoltaic generation and loads forming an island system increases,which poses a serious threat to the safety of maintenance staff.In response to the above problems,the feasibility of such two measures as access to the load and simulation of short-circuit faults at the line incoming end which can be taken by the maintenance staff is analyzedfrom the perspective of maintenance staff.Access to the capacitive load by the maintenance staff at the line incoming end can reduce the cost,reliably make distributed photovoltaic generation operating in islands in the line out of operation,thus ensuring thesafety of maintenance personnel.
