摘要
风电机组在复杂的地形和气象条件下运行时,受到的风向影响可能会不稳定,从而导致输出功率下降。为了解决该问题,文章提出了一种基于运行数据的风电机组对风偏差矫正方法。该方法通过检测风电机组在自由发电状态下的运行数据,归纳计算出各个对风偏差对应的风速-功率曲线。依据此曲线,风速风向矫正系统可分析出在不同风速状态下,各个对风偏差所需要矫正的偏差值,然后采用PI调节的方式进行逐步矫正,直至将偏差值矫正为0°,进而实现精准对风。
When wind turbines operate under complex terrain and meteorological conditions,the influence of wind direction may be unstable,leading to a decrease in output power.To address this issue,this article proposes a wind turbine deviation correction method based on operational data.This method summarizes and calculates the wind speed power curve corresponding to each wind deviation by detecting the operating data of wind turbines in a free power generation state.Based on this curve,the wind speed and direction correction system analyzes the deviation values that need to be corrected for each pair of wind deviations under different wind speed states,and then uses PI adjustment to gradually correct them.Until the deviation value is corrected to 0°,achieving precise wind alignment.
