分布式发电对配电系统的影响

Influence of Distributed Generation on Distribution System

分布式发电是一种与传统供电模式完全不同的新型供电模式。分布式电源大多直接接入配电网,由于分布式电源的特殊性,会对所运行的配电网产生一系列的重要影响。在众多影响方面选取了配网规划、电能质量和继电保护这3个具有代表性的问题进行了讨论,分别阐述了分布式电源对上述3个方面的影响成因、表现以及相对应的措施与方法。

Distributed generation is a new power supply mode, which is completely different from the traditional mode. Accounted the distributed generation connects directly to distribution network, a series of significant impacts on the distribution network may occur for the special nature of the distributed generation. Among these impacts, this paper focused on discussing distribution network planning, power quality and relay protection. From these three aspects, this paper expounded the reason, performance and measures for the impacts.
