说明：  SPWM在pscad的仿真 PSCADTM 一个以图形为基础的电力系统模拟工具族 EMTDC 是一套基于软件的电磁暂态模拟程序, 可以通过PSCAD 进行调用。EMTDC 的威力之一是可以较为简 单地模拟复杂电力系统, 包括直流输电系统和其相关的控制系统。
(SPWM PSCADTM in pscad a graphical simulation based on EMTDC power system simulation tools is a family of software-based electromagnetic transient simulation program PSCAD can be called. EMTDC is the power of one of the relatively simple to simulate complex power systems, including DC transmission system and its associated control system.)
