摘　　要：为了提高风机的风能利用率,偏航控制技术已成为一项重要研究工作。本文简要介绍了风力发电机组偏航控制系统的分类、功能及结构,在此基础上,对当前主流风机偏航控制技术进行了简要汇总,并总结了各自的优缺点,最后在H-C功率控制算法的基础上提出了一种新型偏航控制算法——改进型V-HC算法,通过风向标与功率追踪算法相结合,使风机效率最大化,并且改善了H-C算法下风机的盲动性,使风机的风能利用率得到提高。In order to improve the energy using efficiency, yaw control technology has become an essential research task. The paper presents the sorts, function and structure of yaw control system, on the basis of these, makes a simple summary of the main control technology of wind turbine yaw control system and discusses the advantage and shortcoming of them. In the end, on the basis of H-C algorithm, a new algorithm of yaw control technology--- improved V-HC algorithm has been put forward. This algorithm combines the V-C and H-C control, which makes the turbine efficiency maximization, improves the act blindly of H-C algorithm, and increases the utilization rate of wind energy.
