摘　　要：从理论上分析谐波源对电能计量的影响,通过仿真实验加以验证。依据功率因数调整电费的办法,提出了基于基波功率因数和等值功率因数相结合的电费计量方法。分别对系统侧、线性负荷侧和非线性负荷侧的电费计量进行了讨论,得出了对非线性用户在计量基波电量的基础上,应根据等值功率因数调整其电费的收取,而对于系统和线性负荷用户,则仍采用基波功率因数调整其电费的收取的结论。The paper theoretically analyzes the influence of harmonic sources on electric energy metering, and validates them through simulation experiments. At the same time, according to the power factor approaches for tariff adjustment, it proposes the method of power measurement based on the combination of fimdamental power factor and equivalent power factor. And it discusses respectively the power measurement methods on the system, linear load and nonlinear load. It is concluded that based on the fundamental power measurement, the tariff of the non-linear user should adjusted according to the equivalent power factor, and tariff for the system and linear load customers are still adjusted according to the fundamental power factor.
