分布式发电对配电网继电保护的影响

Effect of Distributed Generation on Relay Protection in Distribution Network

分布式发电安全指数相对较高,避免了传统电路故障时整片区域停电的弊端,但是给配电网继电保护系统的运行造成了不良影响。因此,在实际应用分布式发电方式开展电路管理工作时,需要明确意识到其应用优势,分析其对配电网继电保护产生的不良影响,积极研究有效解决影响的可行方式。

Distributed generation security index is relatively high,which avoids the drawbacks of the whole area blackout when the traditional circuit fails,but it has a negative impact on the operation of the relay protection system of distribution network.Therefore,in the actual application of distributed generation to circuit management,we need to be aware of its application advantages,analyze its adverse impact on distribution network relay protection,and actively study the feasible ways to effectively solve the impact.
