为分析常见家用电器对公共电网的影响,测试了5种家用电器的谐波特性及功率特性,同时对其可能出现的4种组合使用情况的工作特性进行了研究。在进行用电器的组合测试时发现,由于各用电器谐波电流幅值、相角的差异,各次谐波存在不同程度的衰减效应,当用电器负载性质相同时,组合使用后的总体功率因数介于原各用电器之间;当两个用电器负载性质不同时,组合使用后的功率因数要大于原各自用电器功率因数。

To analyze the impacts of common home appliances on the grid, harmonic and power characteristics of five kinds of home appliances were tested, and the characteristics of their four possible combinations were also studied. During testing with a combination of home appliances, due to the differences of the amplitudes and phase angles of their harmonic current, the components of harmonic current decrease to some degree. And when two loads with same properties are used at the same time, the power factor is in the range of the two home appliances; when two loads with different properties join together, the power factor is greater than any one of them.
