摘　　要：提出了统一潮流控制器(UPFC)的分层控制的设计原理,旨在解决复杂电力系统中UPFC的控制律的设计及其实现问题。基于H∞控制理论,论文设计了能连续、快速和稳定跟踪参考信号的换流器的GTO或IGBT触发信号的鲁棒H∞内层控制策略。该控制律中的所有变量均为本地可测量、计算可得参数或装置本身参数,从而与系统的运行方式无关并不依赖电网参数。在多种工况下对UPFC进行的仿真结果表明所设计的鲁棒H∞内层控制器具有较强的鲁棒性以及良好的工程实用性。The paper presents a novel design principle for the design of multi-level controller of UPFC. This design method is useful for the design and implementation of UPFC control in complex power systems. Based on the robust H_∞ control theory, the internal controller is designed to provide continuous and stable control signals for GTOs or IGBTs of converters to track the references quickly. All variables in the control laws can be determined by either direct measurement or calculations, which are independent from the ways that the controller is running , and the parameters of power grid. The simulation results at different operation conditions have shown that the proposed robust internal controller is robust and feasible for engineering applications.
