风电机组动态特性仿真方法研究

Study on dynamic characteristic simulation method of the wind turbine

为了能够准确建立风电机组仿真模型,将风电机组模型分解成三部分,分别采用MATLAB、AeroDyn及FAST三个模型软件进行建模,其中AeroDyn用于建立气动模型,FAST用于建立机组结构模型,MATLAB用于建立控制模型,同时AeroDyn模型及FAST模型嵌入MATLAB控制模型中.尽管该建模方法应用软件多,但是没有增加模型复杂度,而且能够统一平台,集中控制,又能简化系统控制.通过实验对比验证,证明该建模方法有效.

In order to establish accurate wind turbine simulation model, wind turbine model will be decomposed into three parts, and use three model software MATLAB, AeroDyn and FAST, AeroDyn used to establish pneumatic model, FAST used to establish structure model, MATLAB used to establish control model, at the same time , the former two models will be integrated into MATLAB control model. Although there are several kinds of application software for this modeling method, this does not increase the complexity of models. The modeling method can accurately model and simplify control system with a unified platform. Verification by experiment, it is proved that the modeling method is valid.
