In order to meet the increasing demand of wind energy utilization, wind turbines (WTs) are developing toward the trend of large size and large capacity. In such a trend, various advanced yaw control strategies have been proposed to improve large WTs' comprehensive performance, but the analysis and summary of these strategies are still lacking. Therefore, it is necessary to have a review of yaw control, which not only enables readers to understand the current status of yaw control research but also promotes the development of wind energy technology. This paper presents a review of the current situation of yaw control for WTs, focusing on the mechanical/aerodynamic parts. The mechanical part is concerned with the WT yaw system and its effect on the fatigue load of the WT, and the aerodynamic part involves the wind energy capture and wake redirection to reduce the impact on adjacent WTs. In this review, the existing yaw control methods are classified in term of three control objectives: (1) increasing the wind energy capture of a single WT, (2) reducing the fatigue load of a single WT, and (3) maximizing the total power production of the whole wind farm and optimizing the wind farm fatigue load. On this basis, the control mechanism, the control algorithm, and the results are presented and analyzed in detail. Meanwhile, the advantages and disadvantages of the existing achievements are discussed. In addition, in a conclusion of the review, the future research direction has been identified.

大型水平轴风力机偏航系统控制策略综述

为了满足对风能利用的日益增长的需求,风力涡轮机(WT)朝着大尺寸和大容量的趋势发展。在这种趋势下,已经提出了各种先进的偏航控制策略来改善大型WT的综合性能,但是仍然缺乏对这些策略的分析和总结。因此,有必要对偏航控制进行回顾,这不仅使读者了解偏航控制研究的现状,而且促进了风能技术的发展。本文介绍了WT的偏航控制的现状,重点是机械/空气动力学部件。机械部分涉及WT偏航系统及其对WT疲劳载荷的影响,空气动力学部分涉及风能捕获和尾流重定向,以减少对相邻WT的影响。在这篇综述中,现有的偏航控制方法根据三个控制目标进行了分类:(1)增加单个WT的风能捕获量;(2)降低单个WT的疲劳负荷;以及(3)使总和最大化整个风电场的电力生产,并优化风电场的疲劳负荷。在此基础上,详细介绍了控制机制,控制算法和结果。同时,讨论了现有成果的优缺点。此外,在审查的结论中,已经确定了未来的研究方向。现有的偏航控制方法根据三个控制目标进行分类:(1)增加单个WT的风能捕获量;(2)降低单个WT的疲劳负荷;以及(3)最大化风力发电机的总发电量整个风电场,优化风电场疲劳负荷。在此基础上,详细介绍了控制机制,控制算法和结果。同时,讨论了现有成果的优缺点。此外,在审查的结论中,已经确定了未来的研究方向。现有的偏航控制方法根据三个控制目标进行分类:(1)增加单个WT的风能捕获量;(2)降低单个WT的疲劳负荷;以及(3)最大化风力发电机的总发电量整个风电场,优化风电场疲劳负荷。在此基础上,详细介绍了控制机制,控制算法和结果。同时,讨论了现有成果的优缺点。此外,在审查的结论中,已经确定了未来的研究方向。控制算法,并对结果进行详细介绍和分析。同时,讨论了现有成果的优缺点。此外,在审查的结论中,已经确定了未来的研究方向。控制算法,并对结果进行详细介绍和分析。同时,讨论了现有成果的优缺点。此外,在审查的结论中,已经确定了未来的研究方向。
