| 摘 要： | 介绍了３种抑制配电网中非线性负荷产生的高次谐波的方法，即系统极点及其灵敏度分析法、模拟退火法与遗传算法，并就遗传算法作了联系实际的剖析，对自适应遗传算法作了改进，使交换概率和变异概率能根据个体的适应度值自适应地改变。目的是克服传统谐波分析方法的盲目性，合理地优化滤波器在网络中的配置，以较少的投资获得最佳的网络谐波综合抑制效果。

| Abstract: | In order to control the harmonics caused by non linear loads in distribution system effectively, three methods, i.e., system pole and its sensitivity analysis method, Simulated Annealing and Genetic Algorithm (GA) are presented and compared in this paper. The Genetic Algorithm is mainly analyzed on the basis of practical facts, and some improvement of adaptive GA is carried out. The purpose of the improvement is to overcome the blindness in traditional harmonic analysis methods, reasonably utilize the configuration of filters in distribution network, and obtain the optimal restraint of harmonics in distribution network with less investment. |
