摘要
在分析双馈电机(DFIG)数学模型和直接转矩控制(DTC)基本思想的基础上,提出了分段控制策略;采用MATLAB/Simulink对双馈风力发电机组从低风速到高风速的整体运行作了仿真研究。仿真结果表明分段控制策略是可行的。
Based on analysis of doubly-fed induction generator(DFIG) mathematic model and the basic idea of direct torque control, this paper put foward the strategy of setpwise control. By using MATLAB/Simulink,the paper made a simulation research on the whole operation of DFIG from low wind speed to high wind speed. The simulation results show the strategy of stepwise control is available.
