摘　　要：提出了以抑制谐波为目标的并联电容器装置参数优化选择方法,构建了以满足并联电容器装置的连续运行条件和抑制各次谐波放大为约束,以各次谐波放大倍数平方和最小为目标函数的并联电容器装置参数优化模型。模型综合考虑电网谐波响应特性和各种影响因素,包括频率偏差、电抗偏差和电容偏差对并联电容器装置谐波特性的影响。运用粒子群优化算法求解优化模型,给出了具体实现方法。针对工程实例进行了比较和分析。An optimization method on shunt capacitor device parameters to suppress harmonic enlarging as the goal is proposed in the article.Considering power grid harmonic response characteristic and other various affecting factors,including the deviation of frequency and of capacitance and series reactance of the devices,the model is developed with taking to satisfy the continues running conditions of the capacitors and inhibit every harmonic amplify rate after the capacitors turned on as constraints,and the least sum square of harmonic amplify rates as objective function.Particle swarm optimization（PSO） algorithm is used for solving the optimization model and a specific solution is given.According to engineering cases,schemes are compared and discussed.
