摘　　要：文中在简析非线性负荷特性的基础上,结合电能表的工作原理,研究了非线性负荷对感应式电能表和电子式电能表的计量影响。分析讨论了两类电能表在非线性负荷下的计量性能,最后提出基波电能和谐波电能综合计量的电能计量方式。此计量方式在非线性负荷中运用更具科学性和合理性,对保证电能表在此类用电负荷中的精确计量,以及确保供电企业和非线性负荷用户经济利益具有重要的现实意义。Based on the analysis of the characteristics of nonlinear load and the working principle of the electric energy meter, the infuence of the nonlinear load on the induction meter and the electronic energy meter is studied.The measurement performance of the two types of energy meter under the nonlinear load is analyzed and discussed,and fnally put forward the electric energy metering method for comprehensive measurement of fundamental energy and harmonic energy. This measurement method uses more scientifc and rationality in the nonlinear load, which is of great practical signifcance to ensure the precise measurement of the energy meter in such electricity load and to ensure the economic benefts of the power supply enterprises and the non-linear load users.
