Abstract
Taking an accident happened in a large area power grid as the background, this paper builds the models and does a simulation based on PSCAD/EMTDC, and conducts a comparison study of the effect of excitation mode on power system dynamic process. In the simulation, synchronizing generators' excitation systems respectively adopt static excitation model and three-machine separate excitation model. Both of the simulation results of two kinds of models show the basic characteristics of each stage from “N-1”to “N-9” until the end of oscillation, meanwhile, simulation results based on the two kinds of excitation modes have differences, but no qualitative differences. Compared with the separate excitation mode, static excitation mode does not produce unfavorable effect on power system stability in each stage including oscillation stage of the accident.关键词
