摘　　要：合理的电抗率配置是保证并联电容器安全运行的一个重要因素,结合国内电网中因谐振导致电容器损坏的事故,通过理论计算分析和江苏省内的实际运行情况,提出并联电容器电抗率的配置必须考虑3次谐波的影响,阐述了并联电容器串抗率配置的一般性原则,重点对消除3次谐波影响的电抗率配置方案进行了分析及经济性比较,对优化电网内电容器电抗率配置、减少电容器谐振损坏有一定的借鉴作用。Reasonable reactance rate configuration is important for the safe operation of shunt capacitors in substation. This paper illustrates the capacitor damage accidents due to resonance in China, analyzes the actual system operation in Jiangsu Province by means of theoretical calculation, and thereby proposes that 3-harmonic effects be taken into account in the reactance rate configuration for shunt capacitors. In addition, the general principles in reactance rate configuration of series reactors are formulated, emphatically the analysis and economical comparison of the configuration schemes to eliminate the 3-harmonic effects. This research aims to provide reference to the optimization of reactance rate configuration, as well as the reduction of capacitor resonance damage.
