风向变化具有随机性和波动性,基于目标风电场的秒级风向数据,提出一种新的偏航控制阈值确定方法。通过将风向数据划分为多个区间,并计算各区间的风向湍流强度,分析了湍流强度与风力机组功率输出的关系。风向湍流强度反映了风向波动的强度,湍流强度值越大,风向波动越剧烈,导致机组发电性能下降。为提高机组运行效率,本文提出的偏航控制阈值方法结合了湍流强度的区间统计结果,通过调整控制策略提升机组对风向变化的响应灵敏度,有效降低偏航误差,并通过仿真验证了该方法的有效性。研究表明,基于湍流强度的区间化偏航阈值确定方法通过与机械响应的量化映射,可降低传统策略动态响应滞后问题,为智能化风电场控制提供有效解决方案。 |

Wind direction exhibits randomness and volatility. Based on second-level wind direction data from the target wind farm, a new yaw control threshold determination method is proposed. By dividing the wind direction data into multiple intervals and calculating the turbulence intensity (TI) for each interval, the relationship between TI and the power output of the wind turbine is analyzed. The turbulence intensity reflects the in-tensity of wind direction fluctuations. The higher the TI value, the more intense the wind direction fluctuation, which leads to a decrease in turbine power generation performance. To im-prove turbine operational efficiency, the proposed yaw control threshold method integrates the interval-based statistical re-sults of TI. By adjusting the control strategy, the method enhances the turbine's responsiveness to wind direction changes, effectively reducing yaw errors. The effectiveness of this method is verified through simulations. The study shows that the interval-based yaw threshold determination method, based on TI and quantitatively mapped to mechanical re-sponses, can mitigate the dynamic response lag issues asso-ciated with traditional strategies, providing an effective solu-tion for intelligent wind farm control. |
