对“电力系统分析”并补容量计算的商榷

Discussion on Calculation Method of Shunt Capacitor Compensation Capacity in Electric Power System Analysis

就“电力系统分析”中并联电容器补偿容量的计算方法进行讨论。首先介绍目前市面主流教材中并补容量计算的推导过程,分析了公式推导与例题之间的矛盾及产生原因。在此基础上,将求解补偿容量的问题还原为潮流计算问题,提出了改进计算方法,基于Power World Simulator软件进行了改进前后的对比仿真分析,验证了改进方法的正确性。最后,进行了进一步的讨论及教学反思,为课程教学及教材的再版提供参考。

This paper discusses the calculation method of shunt capacitor compensation capacity for reactive power compensation in Electric Power System Analysis.Firstly,this paper introduces the derivation process of complementary capacity calculation in current mainstream textbooks,and analyzes the contradiction between formula derivation and examples and the causes.On this basis,the problem of calculating compensation capacity is reduced to the problem of power flow calculation,an improved calculation method is put forward,and the correctness of the improved method is verified.Finally,further discussion and teaching reflection are carried out to provide reference for the course teaching and the republication of teaching materials.
