摘　　要：采用相似理论和标幺方程一致性,建立风力机比例模型,明确了模拟系统与实际系统的对应关系。设计了由变频器与三相异步电动机构成的风力机与发电机的物理结构,实现了一套风力机模拟实验平台。基于LabVIEW,在上位机实现风力机模型与电机控制策略,并建立了整体监控界面。该平台能模拟不同风速、不同桨距角以及不同输出功率等条件下的风力机特性。实验结果证明了平台构建的合理性和正确性,满足了风电技术教学与实验研究的需要。By using the similarity theory and the consistency of the unitary equation,the scale model of a wind turbine is established,and the corresponding relationship between the simulation system and the actual system is clarified.The physical structure of the wind turbine and generator composed of the frequency converter and three-phase asynchronous motor is designed,and the simulation experimental platform with a set of the wind turbine is established.Based on LabVIEW,the wind turbine model and motor control strategy are realized in the host computer,and the whole monitoring interface is set up.The platform can simulate the characteristics of the wind turbine under the conditions of different wind speeds,different pitch angles,different output powers,etc.The experimental results prove the rationality and correctness of the platform construction,and the platform can meet the needs of the wind power technology teaching and experimental research.
