摘要
电力系统中有谐波存在时,应该了解谐波功率的方向,并按谐波功率的方向确定谐波源的位置。作者从最简单的非线性电路出发,通过比较常规电路的计算结果和频域分析结果,总结了非线性负荷形成谐波功率的特点,提出了确定谐波功率方向的方法,论述了非线性用户的电能计量问题,为进一步完善电能计量工作提供了依据。
The direction of harmonic power flow should be understood and the position of harmonic source can be determined according to the direction of harmonic power while harmonics exist in power network. Stating from the simplest nonlinear circuit and by means of comparing the calculation results of conventional circuit and analysis results in frequency domain, the features of forming harmonic power by nonlinear load are summarized, the method to determine the direction of harmonic power is proposed and electric energy metering of nonlinear power loads is dissertated. These works provide foundation for further improvement of electric energy metering in engineering.
