Modeling And Identification Of Excitation System Parameters Based On PSASP

With the rapid development of the power grid construction in China, stability becomes the main issue to affect the safe operation of power grid. So it is of importance to make calculation and accurate modeling in simulation software and identify the parameters as the basis for dealing with the power system analysis.On the basis of further Analysis of excitation systems'structure,the test makes models of self excited static excitation system and three machines of conventional excitation system,and turns the custom model into standard model with the method of parameter identification.It also points in-depth study of the LIF method,analyses PLPF method,LIF method and frequency domain identification method through simulation and comparison,and summarizes the validation methods to the simulation model and the standard model.
