摘　　要：风能是指空气流做功而提供给人类的一种可利用的能量,它属于可再生能源,对它进行深入的研究并加以利用,是现在科技领域一个重要的课题.若增强风力发电的效率,改进我国能源配置,对能源构建的合理和高效的利用有重大而积极的作用.通过对几种常用变频器优缺点的对比和分析,本文采用新型交流励磁装置-矩阵变换器作为变速恒频交流励磁双馈风力发电系统的转子励磁装置.根据建立的模型,在Matlab/Simulink的环境下对矩阵变换器进行了仿真研究,仿真结果显示了矩阵变换器的输出相电流的各项指标与给定电流相同,追踪能力好,内部反应快,电流波形的正弦度好.从而说明了矩阵变换器具有较好的变频控制性能.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.
