混合滤波系统中无源电力滤波器的优化设计

混合型有源滤波器能否按其工作原理实现预期的谐波抑制效果，在很大程度上还有赖于无源滤波器的优化设计。文章首先介绍了由小容量有源滤波器和无源滤波器串联构成的混合电力滤波系统，继而建立了其无源部分的优化模型，采用改进的遗传算法对系统的投资成本、无功补偿和滤波效果三个方面进行了优化设计研究。为克服算法的早熟收敛现象，引入了混沌算子来增加种群的多样性。工程算例的仿真计算验证了该方法的正确性和可行性，且综合性能较好，C程应用价值较高。

Optimum Design for Passive Filter of Combined Power Filter System

Whether the hybrid active power filter(HAPF) could or not get desirable harmonic eliminating effect,it mainly depends on the optimum design of passive power filter(PPF) . Firstly,a series connected combined system of a PPF and a small-rated active filter(APF) is presented. Then the optimum model for PPF is performed. It macroscopically optimizes for the cost,reactive compensation and the effect of filtering. A chaos operator is introduced to overcome the premature convergence. The results of test and simula...
