摘　　要：当多个谐波源之间的相角不确定时,根据国内外标准,可采用固定叠加系数的方法。在工程实践中,由于各谐波源相角分布不同,叠加时的真实值往往与标准中公式的计算结果不同。为此,通过仿真搭建了多谐波源模型,根据仿真后得出的各类数据,对国家标准和IEC标准叠加公式以及新型叠加公式进行验证。通过计算其误差认为:相较前两种标准中的计算精度,基于功率因数加权线性叠加的方法效果较好。When the phase angle among multiple harmonic sources was uncertain, the method with fixed superposition coefficient was adopted according to both the domestic and overseas standards. In engineering practice, due to the different phase distribution of the harmonic source, the real value of the superposition was often deviated from the calculation result of the formula in the standard. In this paper, a multi -harmonic source model with simulation was built. The national standard and IEC standard superposition formula, and a new type of superposition formula were verified by various simulation data. Through calculating the error, it showed that the method based on power factor weighted linear superposition is better than the other two standards in measuring the calculation accuracy.
