摘要
空间矢量PWM(SVPWM)调制方法具有较高的直流电压利用率,而且由于其采用简单的矢量切换模式更易微处理器实现,因此考虑将它引入到电压源型换流器高压直流输电(VSC-HVDC)的控制当中以期获得良好的控制性能。首先介绍了VSC-HVDC的运行原理,然后在分析了SVPWM调制原理的基础上,着重讨论了如何将其数字实现的问题,最后在建立的VSC-HVDC物理实验系统上进行了实验验证。
SVPWM can improve the using rate of dc voltage, and it can be easily realized on micro- computer because of its simply switching mode , so apply it into the VSC HVDC in order to gain good performance. First the principle of VSC - HVI）C is introduced, then how to realize the SVPWM is discussed based its modulation principle, finally designed an experimental device of VSC- HV[X2 and the results is validated.
