摘　　要：提出一种基于Prony算法的多机PSS参数在线整定方法。对系统输出信号进行Prony辨识得到系统的传递函数和留数矩阵,利用留数相位补偿法计算PSS参数,通过贵州电网数据的仿真结果验证了该方法的可行性和有效性。The method was proposed to set multi-machines PSS parameters online base on the prony algorithm. Firstly, we reached the system transfer functions and residue matrices through analyzing the system output signal and achieving the prony identification, then the residue phase compensation method was utilized to calculate PSS parameters, and this method has been proved feasibility and effectiveness in Guizhou Power Grid.
