摘　　要：分布式电源接入配电网后,影响馈线自动化功能的正常运行,传统就地模式和通信模式依赖单一手段,在分布式电源切除方面具备局限性。提出一种分布式电源切除方法,融合基于区域信息的主动式联切和基于就地保护的被动式解列,实现故障后分布式电源的快速切除。仿真结果表明,对于配电网线路开关采用断路器或负荷开关情况,或是配电网线路开关经保护跳闸或无故障偷跳情况,基于通信保护融合的分布式电源切除方法都可以正确动作,同时对于没有分布式电源接入的配电房,以及在正常区段并网的分布式电源,都不会误切配电网线路。After the distributed generation is connected to the distribution network,the normal operation of feeder automation function is affected.The traditional local mode and communication mode rely on a single means,which has limitations in the terms of distributed generation tripping.In this paper,a distributed generation tripping method is proposed,which integrates the active intertripping based on regional information and the passive disconnection based on local protection,to achieve the rapid removal of distributed generation after a fault.The simulation results show that,for distribution network circuit breaker or load switch is used,or the line switch of distribution network trips through protection or without fault.All the methods based on syncretic communication and protection can work correctly.At the same time,for the distribution room without distributed generations access and the distributed generations connected in normal section,the distribution network lines will not be tripped by mistake.
