MW级风力发电机组变桨距系统建模研究

Modeling Research of MW Wind Turbine Variable Pitch System

由沈阳工业大学研制的MW级变速恒频风电机组属于变桨距型机组,它在额定风速以上进行变桨距调功控制。本文针对该机组的特点,分别建立了关桨过程与开桨过程变桨距系统的控制数学模型,该数学模型是设计变桨距控制律、了解变桨距系统动态特性的基础;应用该数学模型,在MW级模型机上进行实验,得出了系统的正弦响应曲线。

MW variable speed constant frequency wind turbine from shenyang university of technology is a variable pitch wind turbine, it can change pitch to adjust power above rated wind speed. To design variable pitch controller and master dynamic characteristic of variable pitch system, based on variable pitch system characteristic, control model was separately built during close pitch and open pitch, and sine response curve was obtained by experiment with above control model on MW wind turbine model.
