变桨距风力发电机组智能控制的研究

Study on Control Strategy of Variable-speed Variable-Pitch WIND TURBINE

首先分析了风力发电机组控制策略的发展状况。其次根据风力发电机组各部分原理,对气动部分、传动部分和异步发电机部分进行数学模型的建立,并在此基础上在MATLAB中搭建了风力发电机组的子模块。最后设计了基于模糊控制器的控制策略,利用MATLAB/simulink对其进行了仿真,取得了比较满意的控制效果。

In this thesis, first, the development of the wind power generating units various parts is studied. Then some mathematical models about aerodynamic parts, the transmission parts, the induction generator is established according to the principle of the wind power generating units various parts. On the basis, the wind turbine some sub-modules are established in MATLAB. At last, the control strategy based on PID controller is designed and simulated by MATLAB/simulink. The results can achieve a certain degree.
