Research And Application On The Matrix Converter In The Wind Generation System

In this paper, the principle and modulation methods of matrix converter are analyzed, especially deduced the Indirect Space Vector Modulation, and the simulation model is established based on Matlab/Simulink,which verified this method's effectiveness,then, mathematical modle of DFIG is established ,present DPC of DFIG. By matrix converter as DFIG's converter,the simulink modle of DFIG wind Generation System was built. The Indirect Space Vector was introduced in the Matrix converter of the system,DFIG use simple DPC,the combination of them make the wind Generation System gain the most wind energy in the same condition ,and realize to control active power and reactive power independently,the power factor can be adjusted,then the volume of exciter was decreased largely.The result of simulation verified the solution's right and the method of control'effectiveness.
