摘　　要：为合理分配居民用电中的谐波电能,提出了一种适用于居民用户的谐波电能分配方法。在居民用户群的公共节点采集谐波电压、电流数据,通过复线性最小二乘法估算谐波等值电路,将谐波功率进行分解,基于修正系数后的奖惩计量模型得到居民用户群谐波功率,并按照居民用户的用电占比分配各户的谐波电能。最后仿真分析了该方法的谐波电能分配效果,验证了所提方法的合理性和有效性。In order to reasonably distribute the harmonic energy in residential electricity consumption,a kind of harmonic power distribution method for the resident user is proposed.The harmonic voltage and current data are collected at the common node of the resident user group and the harmonic equivalent circuit is estimated by the complex linear least squares method to decompose the harmonic power.The harmonic power of the resident user group is obtained based on the reward and punishment measurement model after the correction coefficient.And the harmonic energy of each household is distributed in accordance with the proportion of electricity consumption of the resident users.Finally,the effect of the method is analyzed and the rationality and effectiveness of the proposed method is verified.
