摘　　要：偏航控制系统是水平轴风电机组控制系统的重要组成部分,风电机组安装之后,受到叶轮紊流、偏航控制策略、风向标零位安装方位角等的影响引起机组偏航控制偏差的出现,直接影响了风电机组的经济性和安全性。分析了偏航控制偏差产生的原因,提出了一种基于机舱式激光雷达测风仪的风电机组偏航控制偏差测试方法,并通过对现场测试数据的分析,提出了考虑风速变化的分段优化方法和建立来流风向和机舱位置风向的传递函数方式对偏航控制偏差优化的建议,提升在运风电机组的发电性能。Yaw control system is an important part of the control system of horizontal axis wind turbine, and its control performance directly affects the economy and safety of wind turbines. After the installation of wind turbines, the different reasons will affect the response performance of the yaw system control,which will lead to the emergence of yaw error. This paper analyzes the reason of the yaw error, and proposes the test method for yaw error of wind turbine based on laser anemometer. Based on the analysis of the field test data,this paper put forward suggestions for the optimization of the yaw error. In the yaw error optimization process, the influence characteristics of the yaw error which affects different power characteristics under the different wind velocity of the power characteristics should be considered. So in the optimization, it is advisable to use the method of partition segment optimization to compensate the yaw error. And for large yaw error, the method can be optimized by setting up the transfer function.
