摘　　要：基于发电机参数和等值系统参数,应用电力系统分析综合程序(PSASP)建立了单机—无穷大系统模型。测取励磁系统无补偿相频特性后,通过拟合补偿相位曲线对相位环节参数进行了整定。仿真结果表明参数整定后的电力系统稳定器(PSS)对低频振荡抑制作用显著。仿真与实测结果对比表明,在工程误差允许的范围内,仿真测取的励磁系统无补偿相频特性可代替实测值。Based on parameters of generator and equivalent system, a single-infinity system model is established by using power system analysis software package （ PSASP ） . After the acquisition of phase frequency characteristics of excitation system without compensation, the parameters of phase link are set by fitting the compensation curve. The simulation results show that the power system stabilzer （ PSS） after setting has significant effect on restrain low frequent oscillation. Comparison of simulation and experimental results show th a t , within the scope of the engineering allowable erro r, the measured phase frequency character of excitation system without compensation could be replaced by the corresponding simulation values.
