电力谐波对电能计量影响的分析与探讨

Analysis and discussion of power harmonics influencing the electric energy computation

在电力系统中,由于非线性用户向电网注入大量的谐波,谐波不仅影响电能质量,同时造成电力部门电能计量表计漏计,本文试从电能的计算原理和电能表的计费原理上探讨谐波造成计量漏计的原因,建议对非线性负载用户的谐波进行综合治理,并采用高精度的电子式电能计费表计,用户和供电部门都能获得很好的经济效益。

In electric power system, a mass of harmonics are poured into the power grid from the nonlinear user, which not only affects the quality of electric energy, but also can cause the electric energy gauge omission in the electric power department. This paper tries to discuss the reason that caused gauge omission by harmonics, and carries out the comprehensive management to＇the harmonics of the nonlinear user, and moreover adopts the high-precision electronic watt-hour meter. Both users and electric power supply bureau can gain the remarkable economic profits.
