摘　　要：针对高校新能源、电气和自控专业学生普遍缺乏针对风力机叶片振动控制的实践环节,提出了基于LabVIEW的风力机叶片振动特性与控制仿真实验设计方案,该方案利用LabVIEW搭建了风力机叶片的经典颤振模型,建立叶片振动特性与控制仿真实验系统。整个仿真实验系统,可在多种典型风速场景下进行叶片振动特性实验,同时,可自行设计控制参数,进行叶片PID振动控制和自适应振动控制的仿真。通过直观的虚拟仿真交互系统,有效克服了场地和设备带来的时间、空间上的局限,促进学生对于风力机叶片振动特性的了解,增强了叶片振动控制设计的实践能力。In view of the lack of practical links for vibration control of wind turbine blades among the students majoring in Renewable Engineering,Electrical Engineering and Control Engineering in universities,a design scheme of simulation experiments of vibration characteristics and controlof wind turbine blade based on LabVIEW is proposed.In this scheme,the classical flutter model of wind turbine blade is built by LabVIEW,and the simulation experiment system of blade vibration characteristics and control is established.The whole simulation experiment system can carry out the experiments of blade vibration characteristics in many typical wind speed scenarios.At the same time,students can design control parameters,carry out blade PID vibration control and adaptive vibration control experiments.Through the intuitive virtual simulation system,it effectively overcomes the time/space limitations brought by the site and equipment,promotes the students’understanding of the vibration characteristics of wind turbine blade,and enhances their practical ability of bladevibration control design.
