背景谐波对24脉整流器电能质量发射特性影响研究
Research on Influence of Background Harmonic on Power Quality Emission Characteristics of 24-pulse-rectifier
摘要
Abstract
The background harmonic voltage is an important characteristic parameter in the study of harmonic. in engineering applications,the influence of the background harmonic voltage on the safe and stable operation of the power supply equipment can't be ignored. First of all,the working principle of 24-pulse-rectifier which widely used in rail transit was analyzed,and it's power quality emission characteristics in the ideal condition was verified from theoretical derivation,modeling and simulation. Then,based on model,the influence of the harmonic voltage of Uh5 and Uh11 on the harmonic emission and power characteristics of the rectifier was studied. Finally,the research results are verified by the measured data,which is of great significance to the selection of power point and the power quality management of rail transit.关键词
