Yaw control strategy adjustment for wind turbines
The patent US12071932B1 outlines a method for adjusting a yaw control strategy in wind turbine generator systems. The process begins with the collection of time series data related to the wind turbine, specifically focusing on the wind facing angle and operating durations corresponding to various angles. The method involves analyzing this data to determine the distribution characteristics of the generator set's operating duration at different wind facing angles. If these characteristics meet specific adjustment conditions, the yaw control strategy is modified accordingly to optimize the turbine's performance.
Further elaboration on the method includes the use of Gaussian distribution fitting to assess the variability in operating durations. The system distinguishes between low and high wind speeds, adjusting the yaw control strategy based on the identified conditions for each category. Additionally, the method accounts for the generator state, ensuring that adjustments are made only during power generation phases. The yaw control system is designed to enhance operational efficiency by dynamically responding to real-time data, thereby improving the overall performance of wind turbine operations.
