摘要
由于电力系统非线性负荷的快速增长,谐波污染越来越严重。本文从谐波功率的定义入手,从基波和谐波两方面分析了电源流向。基于PSCAD/EMTDC设计谐波模拟电路,分析谐波对电能计量的影响。并根据仿真结果,分析了基波和谐波对功率测量的交互影响。在此基础上,从电磁感应仪表和电子式电表分析产生电能计量误差的原因。
Due to the rapid growth of non-linear load in power system, harmonic pollution is becoming more and more serious. Firstly, starting from the definition of harmonic power, direction of power flow is analyzed from aspects of fundamental and harmonics at first. Secondly, harmonic simulation circuit is designed based on PSCAD/EMTDC, to analyze the influence of harmonics on electric energy metering. What＇s more, according to the result of simulation, the interaction effect of the fundamental and harmonic wave on power measurement is analyzed. On this basis, the reason of electric energy metering error is analyzed from electromagnetic induction meter and electronic meter.
