为了解决混合有源滤波器(hybrid active pow erfilter,HAPF)参数匹配以及无源部分和有源部分容量的合理分配,提出一种基于小生境遗传算法的多目标满意优化设计方法,较为全面地考虑HAPF的容量、滤波效果、无功补偿等因素,使得多目标参数求解达到协调满意的效果。优化结果表明:有源部分容量仅为滤波器容量的6.4%,电流总畸变率降低到0.8%,同时满足系统无功功率需要,降低了HAPF系统的投资,提高性能价格比,达到HAPF实用化及谐波抑制的目的。
In order to solve the parameter matching of hybrid active pow er filter (HAPF) and the rational allocation of the active and passive parts, a niche optimization design method based on niche genetic algorithm is proposed, which is considered more fully HAPF capacity, filtering effect, reactive power compensation and other factors, so that the multi-objective parameters to achieve the desired effect of coordinated satisfaction. The optimization results show that the active part capacity is only 6.4% of the capacity of the filter and the total current distortion rate is reduced to 0.8%, meanwhile meeting the reactive power demand of the system, reducing the investment of HAPF system, improving the performance-price ratio and achieving HAPF practicality And harmonic suppression purposes.
