三电平VSC-HVDC系统谐波间谐波产生机理分析
Mechanism Analysis of Harmonics and Interharmonics Generated by Three-level VSC-HVDC System
摘要
Abstract
In order to analyze the transfer behavior and the interaction of harmonics and interharmonics generated in the voltage source converter based high voltage direct current(VSC-HVDC)system,and considering a three-level VSC-HVDC system with pulse-width modulation(PWM)control,the generation mechanism of harmonics and interharmon?ics in both AC and DC sides is analyzed theoretically together with mathematical formulations,where Fourier analysis of switching function is also combined. Based on Matlab/Simulink,a model of three-level VSC-HVDC system with PWM control is established. The results of simulation verify the correctness of the mathematical model ,which provides a theoretical basis for the measurement and suppression of harmonics and interharmonics.关键词
