摘要
针对有源滤波器造价较高,难以得到广泛应用的情况,在较为全面地考虑了单独注入式有源电力滤波器(HAPF)中无源部分和有源部分的容量匹配、滤波效果、无功补偿等因素基础上,通过基于模糊理论的多目标优化设计方法,降低了有源谐波补偿系统的投资,达到HAPF参数优化的效果。实例设计表明:与根据经验设计的参数相比,经优化设计的参数降低了HAPF系统的投资,提高了性价比,对系统工程应用有一定参考借鉴价值。
Harmonics are typically caused by the use of non-linear loads such as switch mode power converters, fluorescent lamps, arc furnaces, and welding equipment. Harmonics increase losses in all components connected to the power system and cause voltage distortion problem. Accordingly, a multi-object optimization design method is put forward based on the fuzzy theory by considering factors as capacity of HAPF, filtering effect, reactive power compensation. The method fully reduces investment in active harmonic compensation system and accomplishes the effect of HAPF parameter optimizing. The practical design indicates that, compaved with the parameters based on experience design, the optimized design reduces the investment of HAPF system and improves the performance, and can better meet the needs of whole system engineering application.
