风力发电机组变桨距控制策略研究

Study on Variable—Pitch Control Strategy of Wind Turbine System

在对风力发电机组运行特性分析的基础上,针对发电机组桨距的控制问题,利用模糊理论和PID理论设计了智能变桨距控制器,并建立了相应的仿真模型,仿真结果验证了控制器可以在风力发电机组数学模型未知的情况下,保证了系统的可靠运行,获取最大能量。

An intelligent controller using both neural network and PID control is designed for the pitch control of wind turbine system based on features analysis of Wind Turbine System. And then the emulation model is built and the emulation experiment show that the controller is fully designed to keep the system operating stability and getting the biggest energy without the precise model of the wind turbine system.
