摘　　要：提出一种基于测试信号法的统一潮流控制器(UPFC)附加阻尼控制器设计方法。首先运用测试信号法进行系统小信号稳定性分析;然后运用测试信号法求得从UPFC有功功率指令值到并联交流联络线有功功率的开环传递函数;最后基于经典控制理论的极点配置算法便可整定UPFC附加阻尼控制器的各个参数。利用PSS/E验证了所设计的UPFC附加阻尼控制器的有效性。以南京西环网系统为例,验证所提出的UPFC附加阻尼控制器设计方法在实际电力系统中应用的有效性。In this paper, a new method of UPFC auxiliary damping controller parameters tuning based on test signal method is proposed. First, the small signal stability of power system is analyzed using the test signal method. Then the testing signal is scanned at the line active power setting point of UPFC while the active power flow in the parallel AC tie line is oscillated. The open-loop transfer function between the line active power setting point of UPFC and the active power flow in the parallel AC tie line is identified by Fourier resolution and curve fitting. Finally, the parameters of UPFC auxiliary damping controller are tuned based on the root locus rules of the classical control theory. The proposed parameter tuning method is validated by the simulation results of a simple case and a real power grid.
