配电网中小电源等效容量法的比较研究

Comparison of Equivalent Capacity Method of Small Power Sources in Distribution Networks

针对小电源在电网中的处理方法作了探讨,对文献[1]中提出的等效容量法在实际进行了运用并发现其存在的问题,从而又提出一种更为切实可行的等效容量法,即借助于视在功率来获得小电源的等效容量,在广东省几个实际电网中进行应用后表明:该法简单、有效可行,不会出现偏常的等效容量和线损率。

Discussed on the processing methods of small power source in distribution network, usea me equivalent capacity method in practice, which was presented by literature [1], and discovered its problems, a new and more available equivalent capacity method is presented, according with which the equivalent capacity of small power source could be obtained by means of apparent power. Used this method in several distribution networks in Guangdong province, what it is simple, effective and not with unnatural equivalent capacity and unnatural line loss rate are confirmed.
