摘要

本文针对模块化多电平拓扑结构换流器

基于PSCAD-EMTDC建立谐波仿真计算模型

研究最近电平逼近与载波移相两种不同调制策略下电平数与谐波含量之间的关系

为换流器选择合适的调制策略提供重要技术支撑。

Abstract

This paper establishes the harmonic simulation model based on PSCAD-EMTDC

researches the nearest level and carrier phase shift modulation strategies for the modular multilevel converter topology structure

and gets the relationshi between level numbers and harmonic contents. The research conclusion provides important technical support of selecting a suitable modulation scheme for converters.
