Generation of harmonic wave of electrical network and prevention of its harmfulness 电网谐波的产生与危害及其防治措施
In this paper , the principle of spwm is described , which include how the harmonic is engendered 论文分析了spwm技术的原理和其谐波的产生和危害。
In this paper , we analyze three kinds of typical harmonics in power system . the main method of monitoring of high harmonics is depicted 本论文首先系统的论述了国内外电力网谐波的产生及其危害,以电力系统中主要出现的三次谐波为例,论述了对谐波进行监测的必要性。
In order to improve the electric power supply quality , a measure device is needed to analyse the distrubtion of the harmonic pollution in the power supply system 因此有必要对电网中的谐波含量及非线性用电设备可能产生的谐波畸变进行检测,掌握谐波的产生和分布情况,以便采取措施抑制谐波危害,提高供电质量。
Secondary , this paper expatiates on the harmonic generation , harmonic harm , harmonic analysis and the hardware for measuring harmonics , analyzes and discusses the method applied to measure harmonics 其次,本文概述了谐波的产生、谐波的危害、谐波的分析及谐波测量的硬件实现,对应用于谐波测量的方法进行了分析和评述。
