摘要
偏航系统是大型风力发电机组的重要组成部分,它保证机组正确对风以捕获尽可能多的风能。在机组正常运行中,偏航系统的对风性能有较大差异,难以评估。针对这一问题,提出了一种基于机组SCADA数据的偏航系统性能分析方法,使用机组对风角度的平均值与标准差来衡量偏航系统性能。实际结果表明,该方法可以有效表征偏航系统性能,从而提高风电场的运维水平。
Yaw system is an important part of large-scale wind turbine, it guarantees the wind turbine properly to the wind to capture as much wind as possible. In the normal operation of unit, yaw system performance is different and difficult to assess. Aiming at this problem, this paper proposes a yaw system performance analysis method based on SCADA system. We use the mean value and standard deviation of vane direction to measure the yaw system performance. Actual results show that the proposed method can effectively characterize the yaw system performance, so as to improve the operational level of wind farms.
