摘　　要：为区分多谐波源负荷对公共点的谐波责任,提出一种基于组合赋权法的多谐波源责任综合评估方法。将各次谐波电压含有率作为评估指标,采用优序图与熵权的组合赋权法得到的综合评价结果对谐波电压等级进行评估:定性分析了各负荷应负的谐波电压责任,定量比较了根据组合赋权法求得的加权谐波电压值。从主、客观方面采用组合赋权法对含有多谐波源系统进行责任综合评估,其评估结果客观、合理,具有一定的工程实际意义。In order to distinguish the harmonic responsibility of multi harmonic sources load for the common point,a comprehensive evaluation method of the responsibility of multi harmonic sources is provided based on combination weighting method.The harmonic ratio of the harmonic voltage is used as the evaluation index,and the comprehensive evaluation result of the combination weighting method of superiority chart and entropy weight is used to evaluate the harmonic voltage level.The responsibility of multi harmonic sources load is qualitatively analyzed,and the weighted harmonic voltage value according to the combination weighting method is quantitatively compared.The combination weighting method is used to evaluate the responsibility of multi harmonic sources through subject and objective aspects,and the result is objective and reasonable,which is practide in engineering.
