摘要
分析开关磁阻发电机(switched reluctance generator,SRG)的结构特点和发电模式及其非线性数学模型;在Matlab/Simulink中建立SRG的非线性仿真模型,对SRG采用电流斩波控制方式;通过仿真,验证了SRG非线性模型的正确性,在不同风力驱动下SRG能输出稳定的电压,实现变速恒频风力发电。
The structural features of switched reluctance generator (SRG), its power generation modes and its nonlinear mathematical model are researched; then by means of Matlab/Simulink, a nonlinear model of SRG is established and the current chopping control is applied to SRG. Simulation results not only verified the correctness of the proposed nonlinear model of SRG, but also proved that driven by different wind power SRG can output stable voltage, thus variable-speed constant-frequency (VSCF) wind power generation can be implemented by SRG.
