风力机偏航系统控制策略研究现状及进展
摘要：在风力机运行过程中，由于风向具有随机性及波动性，风力机偏航系统需要完成对风控制，频繁偏航将导致风力发电机组故障。综述了风力机偏航控制现状及策略，通过对偏航执行策略和重启策略的分别评述，可知大多偏航执行策略的研究仍是在仿真工具上实现，风向预测在执行偏航策略中有更多的体现。偏航重启策略开展研究较少，主要是对风速及风向的阈值进行修正，优化偏航重启的阈值以达到减少偏航次数的目的。偏航控制策略可以减少单机故障发生概率，同时增加风电场功率，提高全场综合经济效益。
Abstract:Due to the randomness and volatility of the wind direction, wind turbine orientation control used on the yaw system of the wind turbine, and the failure of the wind turbine led by yaw frequently. The current situation of yaw control strategy was reviewed. The execution strategy and reboot strategy were reviewed separately. It is concluded that most of the yaw execution strategy research were still implemented on simulation tools, and the wind direction prediction was more reflected in the yaw execution strategy. Few studies have been carried out on yaw reboot strategy, which is mainly to modify the threshold value of wind speed and direction. Yaw control strategy can reduce the probability of failure, increase the power of wind farms and improve the overall economic benefits.
