三电平SVPWM变频调速系统的PSCAD/EMTDC仿真

摘要

The basic principle of space vector pulse width modulation for three-level speed control system is discussed in this paper. A simulation model of this system is built by the electromagnetic transients program PSCAD/EMTDC aimed at implementing the field orientated control. The validity of the proposed method is demonstrated by the simulation results.%本文分析了三电平空间矢量脉宽调制的基本原理,应用电磁暂态分析软件PSCAD/EMTDC搭建了基于三电平逆变器的感应电机调速系统模型,实现了电机的矢量控制。仿真结果证明了该方法的有效性。
