提高电网无功补偿效益的原则和方法

Discussion on the methods and principle of Improving Power Network's Reactive Power Compensating Benefit

从无功经济当量的推导计算入手 ,将无功经济当量概念扩展为补前无功经济当量 C1,补后无功当量 C2 和无功补偿当量 C,并引入无功临界当量 Ccr和临界补偿容量 Qcr两个新概念 ,导出了计算公式 ,论述了无功优化补偿的原则和方法 ,对搞好电网的降损节电和经济运行 。

It discusses a method for reactive power optimization compensation.Starting with the deduction and calculation of reactive power Economic Equivalence,and extends the concept of reactive power Economic Equivalence to as pects before compensation reactive power Economic Equivalence(C 1),after compensation reactive power Economic Equivalence (C 2) and reactive power compensation Economic Equivalence(C).The method introduces two new concepts(reactive power critical Economic Equivalence (C cr ) and critical compensation capacity(Q cr )),and deduces calculating formula.This principle is very important to reducing wasting of power network and it is good to economic operation.
