摘　　要：建立了200MW同步发电机和双输入PSS辅助控制励磁系统模型,通过算法设置了模型参数,基于MATLAB/SIMULINK平台,对暂态条件下双输入PSS励磁系统和常规PID励磁系统进行了仿真和比较,仿真试验结果表明,双输入PSS励磁系统具有很强的鲁棒性,增强了系统的阻尼特性,且发电机的抗扰动、抑制低频振荡和故障后恢复等性能优于常规PID励磁系统,为实际应用的真实性奠定了基础。This paper established models of 200MW synchronizing generator and dual input PSS minor controlled excitation system. Through the algorithm, it set the model＇s parameter. Based on MATLAB/SIMULINK, it made simulation and comparision of the dual input PSS minor controlled and the conventional PID excitation system under transient condition. The results showed that, compared to the excitation system controlled by PID method, the dual input laSS excitation system had nicer roubustness, which could increase damp trait of the system, restrain the interference, low frequency oscillation and recover of short cat.
