变速变桨风力发电机组的建模研究

Research on Wind Turbine with Variable Speed and Blade

风力发电系统结构复杂、体积大,风力发电系统控制的研究工作存在很大的困难.通过采用机理建模的方法建立变速变桨风力发电系统的数学模型.分析了风力发电机组各部件的数学模型,其中有传动系统模型、发电机模型、风轮系统模型,并将子模型整合在Simulink中,得到可靠的系统仿真模型.

As power generation system has the characteristics of the volume and complex structure,it＇ s quite difficult to control the system.The mechanism modeling method is adopted to establish the mathematical model of wind power generation system.Each component of a wind turbine model is analyzed,including wind turbines system,transmission system and the generator model.The sub-models are integrated into Simulink to get a reliable simulation model.
