Abstract

The number of nonlinear loads has increased in power systems increasing the harmonics present and this could cause detrimental effects to the system and users. The harmonic current distortion indices are affected by linear loads connected in parallel to the system. The aim of this paper is to quantify the effect of linear loads on the harmonic indices including Total Harmonic Distortion (THD) and Individual Harmonic Distortion (IHD) up to 11th order. The linear load to be considered is an Incandescent Lamp (IL) while the nonlinear loads are a Personal Computer (PC), Fluorescent Lamp (FL) and laptop. Laboratory measurements are performed for this purpose.

线性负荷引起的非线性负荷谐波衰减
电力系统中非线性负荷的增加增加了谐波的存在,这可能对系统和用户造成不利影响。谐波电流畸变指标受并联的线性负载的影响。本文的目的是量化线性负载对谐波指标的影响,包括总谐波失真(THD)和个别谐波失真(IHD)高达11阶。要考虑的线性负载是白炽灯(IL),而非线性负载是个人电脑(PC),荧光灯(FL)和笔记本电脑。为此目的进行实验室测量。
