| Abstract: | The principle of parameter identification of generator excitation system is described.Then based on Prony algorithm,this paper proposes a new and practical method to identify excitation system parameters.The advantage of this method is that the parameter can be identified in time domain directly according to input/output response signals of excitation system.The simulation results in Matlab/Simulink show that this algorithm can accurately identify all the excitation system parameters with higher precision,operation efficiency,and program versatility. |
