摘要
利用Matlab/Simulink仿真软件,建立风力发电系统仿真模型。根据不同时间段的风速情况,对风力发电机组的转速进行调节控制,使其保持在最佳叶尖速比下运行,进而使用PI控制技术实现最大风能捕获。仿真结果表明:这种控制策略可以有效地提高风力发电系统的效率,能够对输出功率进行追踪控制。
Using Matlab/Simulink simulation software, a wind power system simulation model is established. Accord-ing to the wind speed of different time periods, the wind turbine keeps the optimum tip-speed ratio by adjusting the speed of wind turbine, and then achieves maximum wind energy capture by using PI control technology. The simula-tion results show that this control strategy can effectively improve the efficiency of wind power generation system, therefore track and control the output power.
