整流装置谐波分析

Analysis on harmonic wave of rectifying equipment

叙述了整流装置电流波形畸变的原因,介绍了电能质量公用电网谐波治理国家标准及谐波计算方法,以某大型化工电解装置谐波计算为例,分析说明为达到国家标准,使谐波电流不超标,理论上需要24脉波整流。

The reasons of distortion of wave form of rectifying equipment was narrated. National standards of harmonies in public supply network for quality of electric energy supply and caculation method were introduced. Take the ease of the harmonic caculation of a big scale chemical electrolysis equipment, 24- pulse rectifying is the theoretical value for national standards and haromonic current without above-norm.
