摘要
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。
Taking actual wiring of substation for example, this paper analyzed unfavorable effect on recloser and power supply automatic switch device because of distributed generation connected-in, and effective solution was raised. As for reeloser, 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 switching device, carrying out improvement for power supply automatic switching action logic. The solution plan has certain engineering value for popularization application of distributed generation.
