摘要 统一潮流控制器(UPFC)是柔性交流输电系统(FACTS)控制器中极具发展潜力的一种,也是电力系统研究领域中新的热点.利用开关函数模型法,考虑直流电容上的电压波动,建立了UPFC的动态模型;利用空间电压矢量控制技术和坐标变换思想,给出了一种解耦控制策略.为UPFC控制装置的实现,奠定了一定的理论基础. Unified Power Flow Controller (UPFC) is a kind of FACTS controllers with great potential and is a new hot topic of Power System research. This paper establishes a dynamic model of UPFC using switch function, taking into consideration voltage fluctuate of capacitance. Using the technology of SVP-WM and the idea of coordinate transformation, an uncoupling control strategy is proposed.
