| 摘 要： | 大型风力机在实际运行中受风速、风向的变化影响很大。针对定速变桨型风力机分析其偏航与桨距调节控制策略,提出"桨距分段控制"新的控制策略,即根据不同的来流风速设计执行相对应的桨距控制策略。并通过LabVIEW软件设计1.5 MW的风力发电机测试与控制系统,实现提出的新控制策略。结果表明:分段控制策略能够快速地对来流风速的变化作出反应,提高了控制精度和系统的稳定性。

| Abstract: | The performances of wind turbines were largely influenced by the changes of the wind direction and the velocity.The control strategy of the yaw and pitch adjustment was analyzed.A new control strategy(sectional control method)was proposed.Different control strategies were implemented by wind velocity condition in this strategy.According to the strategy,a 1.5 MW wind power turbine test control system based on LabVIEW technology was designed.The results showed that the control strategy velocity couldquickly change the velocity,thus improving the system stability and the control precision. |
