摘　　要：利用风电机组运行风数据结合常规测风塔和激光雷达观测风数据,对机组运行风数据进行相关性分析和检验,建立机组机舱湍流强度的计算方法和适用范围。研究表明,基于机舱风数据计算的湍流强度大小虽不能代表机组实际湍流的绝对值大小,但对于简单平坦地形,不同机组机舱湍流强度的相对变化,可作为评估风电场微观选址设计机组尾流影响程度的参考标准之一;对于复杂地形,不同机组机舱湍流强度的差异能很好表征不同地形下环境湍流的差异及对机组实际运行功率的影响。Through testing and correlation analyzing the SCADA （Supervisory Control and Data Acquisition） system data with the measured data of mast and lidar, the calculation methods about the turbulence of wind turbine and the scope of application was established. Although the turbulence intensity calculated by the SCADA data isn＇ t equal to the value of actual turbulence of wind turbines, the relative variation of turbulence intensity of each wind turbine can be part of the reference standard about the assessment of the wake interference for each turbine in fiat terrain. For complex terrain, the differences of the turbulence intensity between wind turbines reflect the differences of ambient turbulence under the various terrain and the effect on the actual power curve of wind turbines.
