分布式电源对重合闸和备自投装置的影响及解决方案

摘要

Taking actual wiring of substation for example, this paper analyzed unfavorable effect on recloser and power sup-ply automatic switch device because of distributed generation connected-in, and effective solution was raised. As for recloser, this paper raised adopting line protection action joint tripping distributed generation; as for power supply automatic switching device, this paper raised using tripping line spare connecting point joint tripping distributed generation of power supply automatic switch-ing device, carrying out improvement for power supply automatic switching action logic. The solution plan has certain engineering value for popularization application of distributed generation.%　　以变电站的实际接线为例，分析了分布式电源接入对重合闸装置和备自投装置带来的不利影响，并提出了有效的解决方案：对于重合闸，提出采用线路保护动作联跳分布式电源；对于备自投，提出利用备自投的跳进线备用接点联跳分布式电源，并对备自投动作逻辑进行改进，该解决方案对分布式发电的推广应用具有一定工程价值。
