摘要

为了达到电容器的优化配置

避免配电网中电容器与系统、负荷阻抗发生串并联谐振

在考虑谐振的情况下

数学模型上将电容无功功率与串并联谐振频率的关系作为约束条件

采用改进的粒子群优化算法（PSO）

提出时变的非线性三角函数方法来控制参数对电容器进行优化配置。最后将优化配置的电容器与优化前的经济费用、网损等进行比较

结果表明优化配置后的电容器具有明显的经济性

且有效地避免了谐振的发生。

Abstract

As for the problem of the series and parallel resonance between the capacitors and the system impedance and load impedance

in order to achieve the optimal allocation of capacitors and to avoid resonance

the relationship between the capacitive reactive power and series and parallel resonant frequency is put as a constraint in the mathematical model

considering the resonant case.The improved particle swarm optimization（PSO） that is time-varying nonlinear trigonometric functions to control parameters is proposed to optimize the allocation of the capacitor.Comparing the net loss and economic costs etc before and after the optimal allocation of capacitors

the results show that after the optimal allocation of the capacitors

it will be more economical

and effectively avoid the occurrence of resonance.
