Doubly-fed Wind Power Generating System of Exciting by Matrix Converter

Wind is air flow work and provide an available energy for human beings,it belongs to renewable energy,an in-depth study on it and use it,is now an important subject.If the enhanced the efficiency of wind power generation,it may improve our energy allocation of energy construction,reasonable and efficient utilization,has a significant and positive role.By comparison and analysis of the advantages and disadvantages of several common transducer,the AC excitation device-matrix converter may use as the rotor excitation device of AC excited VSCF doubly fed wind power generation system. Based on the model,the simulation research on matrix converter in the Matlab/Simulink environment was made,the simulation results show the indicators and given the current output of the matrix converter phase current,tracking ability is good,the internal reaction speed,current wave form is good. So the matrix converter has good control performance of variable frequency.
