Control for Maximal Wind Energy Tracing in Matrix Converter AC Excited Brushless Doubly-Fed Wind Power Generation System

Using rotor d-q model as a start point, this paper analyses the mathematical model for BDFM based on synchronous reference frame. And, based on characteristics of BDFM, a new type of power control system is designed by using the gap flux oriented vector transformation control technology. In order to no existing of the big power storage capacitors, the matrix converter is used to control windings of the generator to carry out the AC excitation in the paper. Thus high efficiency energy generation is achieved through maximal wind energy capturing. Simulation results verify the correctness and effectiveness of this control strategy.
