摘　　要：随着电网中非线性感性负荷的增加,并联电容器引发的谐波问题逐渐突出。介绍了并联电容器装置的谐波简化计算,重点对采用传统简化模型的谐波放大率、谐振容量计算公式进行了推导,分析了电容器组投入后的特征谐波次数,推荐了谐波放大允许倍数,论述了电抗率的求取方法,对电容器组配置不同电抗率的谐波响应进行了分析。分析与计算可供并联电容器装置工程设计时参考。With the increase of nonlinear inductive load, the problem about harmonic caused by the shunt capacitors is more and more severe. The paper introduces the simplified harmonic calculation for the shunt capacitor installation and derives the calcullation formula of harmonic amplifying rate and resonance capacity using the traditional simplified model, analyses the character harmonic order after the capacitor bank has been turned into operation, recommends the allowable multiple of the harmonic amplifying rate, discusses the way to evaluation the reactance ratio, and analyzes the harmonic response of capacitor bank under different reactance ratio. The result is valuable for the engineering design of shunt capacitor installation.
