摘　　要：风力发电机组的发电量通过功率曲线和对应风频分布计算得出,功率曲线通过功率曲线测试获得,风频分布通过长期测风数据获得。然而功率曲线在测试过程中,由于环境因素不同以及测试周期有限等原因,称为特定环境条件下的功率曲线,与理论功率曲线有所偏差。通过研究湍流强度对功率曲线的影响,利用理论方法修正测试功率曲线到特定湍流强度,以达到更准确评估实际发电量的目的,为风电场评估项目发电量以及机组性能提供更可靠的理论依据。The energy production of wind turbine is calculated by power curve and corresponding wind frequency distribution.The power curve is obtained through the power curve test,and the wind frequency distribution can be obtained by long-term wind measurement data.However,in the test process,due to different environmental factors and limited test period,the power curve is called the power curve under specific environmental conditions,which deviates from the theoretical power curve.By studying the influence of turbulence intensity on power curve,this paper modifies the test power curve to specific turbulence intensity through theoretical method,so as to achieve the purpose of more accurate evaluation of actual energy production,and provide a more reliable theoretical basis for wind farm evaluation of power performance.
