摘要
静态偏航误差普遍存在于风电机组的偏航控制中,为了研究风电机组的静态偏航误差,对偏航误差产生的原因和对功率的影响进行了分析。利用机舱式激光雷达测风仪对风电机组的静态偏航误差进行校正,通过修正主控系统的风向补偿因数,改变主控系统采集的风向角度。对比风向补偿因数修正前后的静态偏航误差变化趋势,验证了利用激光雷达测风仪进行静态偏航误差校正的正确性。
Static yaw error is prevalent in yaw control of wind turbine generator. In order to study the static yaw error of wind turbines, the causes of yaw error and the influence on power were analyzed. The static yaw error of the wind turbine was corrected by the nacelle-type LIDAR. By modifying the compensation factor of the wind direction in master control system, the wind direction angle collected by the master control system was modified. The static yaw error corrected by LIDAR anemoscope was verified by comparing the variation trend of static yaw error before and after the correction of the wind direction with compensation factor.
