| 摘 要： | 工业中的电网谐波不但降低了电能的质量,还可能引起故障甚至事故,因此有必要对电网谐波进行有效地滤除;实际的工程实践中,无源滤波器常被用来滤除该谐波,而其滤波参数的确定是个关键;基于带精英策略的非支配排序遗传算法NSGA-Ⅱ,文中提出了一种新的无源滤波器的参数优化方法,克服了传统的凭个人经验选择滤波器参数的缺陷.利用NSGA-Ⅱ对无源滤波器进行参数优化,不仅能节省初始投资,还能更有效地消除谐波干扰;仿真结果证明了该方法的有效性.

| Abstract: | The harmonic interference in the industrial process can deteriorate the quality of electricity energy,and it may cause some faults,even accidents,so the elimination of the harmonic interference is a necessity.Practically,the passive filter is used to attain this goal,and its parameters are very important.Based on Non-dominated Sorting Genetic Algorithm with elitism approach(NSGA-II),the optimization of passive filter's parameters is presented.Conventionally,those parameters are chosen by personal experience,and can hardly reach the optimal point.With the parameters of passive filter optimized by NSGA-II,the minimum investment is obtained,and the harmonic interference is effectively eliminated.The simulation results show the effectiveness of NSGA-II. |
