Abstract  The main source of harmonics of residential power systems is the nonlinear appliances. The harmonic characteristics were attracted by measuring the typical nonlinear devices, and the harmonic current source models for those typical appliances were established. The equivalent harmonic contribution index for evaluating harmonic contributions based on harmonic magnitude characteristics and harmonic compatability index for evaluating the diversity effect based on harmonic phase angle characteristics of such loads were proposed. According to the actual combinations of such loads in residential environment, the harmonic characteristic investigation for various combinations of nonlinear loads was performed. The range of total harmonic current distortions of these combinations was obtained. And it concluded that the third harmonic was the major contributor for the total harmonic distortion. The field test results confirmed the conclusions.

住宅配电系统的谐波特性研究

住宅配电系统谐波主要来源是住宅的非线性用电设备.运用实验方法,对典型住宅非线性用电设备进行谐波测试,提取其特征,建立了典型住宅非线性用电设备的谐波电流源模型.提出了基于谐波幅值特征、反映谐波贡献大小的非线性用电设备谐波等效贡献指标,以及基于谐波相位特征、反映谐波分散效应的非线性用电设备谐波兼容性指标.根据该类用电设备实际使用时的组合方式,对不同用电设备组合的集合谐波特性进行比较分析,得到不同用电设备组合时可能的谐波电流总畸变率变化范围,得出3次谐波是组合谐波总畸变率的主要贡献者的结论.对实际运行的住宅配电系统的监测结果,证明了上述结论的正确性.
