Design and simulation of excitation control system for brushless doubly-fed generator

In this paper, a new type, brushless, double-fed generator as wind generator was studied. According to Parkpsilas equation, the mathematical model for the generator and the mathematic model of doubly PWM converter are given. And with these mathematic models, the performance of brushless wind-driven double-fed generator was simulated. Second, the control strategy of the excitation system is discussed. At last, an experiment system and a practical scheme of excitation control system is given and some simulation and experiment result was presented.
