浅谈电网谐波对电能计量影响的仿真分析

Simple Discussion on the Simulation Analysis of the Influence of Harmonics in Power Grid on Power Metering

在电网运行的过程中,谐波是电力电子装置等非线性的负载,其在很大程度上会影响电网中的电压和电流,并造成电能计量出现不精准的情况,严重威胁了我国电能计量工作的正常运行.本文主要对谐波产生的原理进行了研究,并分析了谐波造成电能计量不准确的主要机理以及相应的调整计量的方式,希望能够在一定程度上提供有价值的参考.

In the process of power grid operation,harmonics are non-linear loads such as power electronic devices,which will affect the voltage and current in the power grid to a large extent,and cause inaccurate power metering,which seriously threatens the normal operation of power metering in our country.Therefore,this paper mainly studies the principle of harmonics generation,and analyses the harmonics causing power meters.The main mechanism of inaccuracy and the corresponding ways of adjusting measurement are expected to provide valuable reference information to a certain extent.
