Design and Simulation of Excitation Control System for Doubly-Fed Generator

In this paper, a new type, double-fed generator was studied. According to Park´s equation, the mathematical model for double-fed generator and the mathematic model of cycloconverter are given. And with these mathematic models, the performance of double-fed generator was simulated. Second, the control strategy of the excitation system is discussed. At last, a new practical scheme of excitation control system is given and some simulation result was presented
