摘要
作为风力发电机组的关键部件,偏航系统的设计精确性直接决定着机组的使用寿命。文章提出了一种偏航系统的优化控制设计方案,采用的方法是基于功率控制的爬山算法,这种方法可以改善风向变化的绝对值小于15°时偏航控制系统的精度。为验证其准确性,采用Matlab仿真软件建立的偏航控制系统仿真模型进行了仿真实验。仿真结果表明,采用爬山算法可以在保证风能最大捕获的基础上,提高偏航控制系统的精度,优化风力发电机组的偏航控制系统。
As yaw system is a key component of wind turbine, its accurate design directly determines the service life of unit.An optimal control design of yaw system is presented, which adopts the method of hill climbing algorithm based on power control to improve precision of the yaw control system when the angle between the wind direction and the orientation of wind turbine rotor is less than 15 degree.A simulation model of proposed yaw control system is established to verify its correctness by using MATLAB simulation software, the simulation results show that the hill climbing algorithm can improve the accuracy of yaw control system on the basis of the maximum capture of wind energy.
