A simplified dynamic model of six-phase electrically excited synchronous wind generators

摘要

Six-phase electrically excitation synchronous wind generator (SP-EESWG) is a special kind of variable speed constant frequency wind generator. A simplified dynamic model of SP-EESWG suitable for transient stability simulation is presented in this paper by ignoring the harmonics within the AC-DC-AC converters and fitting the steady active-reactive power relationship of uncontrollable rectifiers. The simplified model is tested on a single-machine infinite-bus sample system, by comparing its dynamic responses with those of the MATLAB/Simulink model of the same sample system.
