摘要
讨论了已实现的 UPFC物理模型中 SPWM技术存在的问题,介绍了消除谐波常用的优化消 谐 PWM算法的原理及求解方法,利用 UPFC换流器结构特点,对该算法进行简化并进行了初值选择研究,给出了一种在线快速求解非线性方程组的方法,为该方法在UPFC物理模型中的应用奠定 了基础。
The encountered problems in UPFC prototype by using SPWM method is discussed in this paper. A selective harmonic elimination(SHE) PWM method is introduced. Having considered the converter structure, a fast online computing method of solving the nonlinear coupled equation is given by simplifying the coupled equations and analysing the initial value selection, these lay the foundation for the application of SHE PWM technique in UPFC.
