摘　　要：风电机组功率特性是评估风电机组发电效益的重要指标,由测量功率曲线和年发电量（AEP）决定。在运风电机组会由于设备部件老化、维护不当等原因导致功率曲线退化、年发电量下降,进而影响风电场的经济效益。通常采用单独树立测风塔测试风电机组的功率曲线,测试过程复杂,测试成本较高。文章采用激光测风仪进行风电机组功率特性测试,得到了功率曲线的实测结果和年发电量的评估结果。通过将实测曲线与理论曲线进行对比分析,探讨了功率曲线和年发电量评估差异的关键影响因素。
Wind turbine power performance, decided by the measuring power curve and annual energy production （AEP） ,is an important indicator to assess the wind turbine power generation benefit. Equipment component aging, improper maintenance and other causes make the working wind turbine power curve degenerate and annual energy production decline,which affects the economic benefits of wind farm. Usually, power curve test needs to establish a separate wind tower. The test process is complex and costs much. In this paper, using laser anemometer to test wind turbine power performance obtained the measured results of power curve and the assessment results of annual energy production. By comparing the measured curve with the theoretical curve, this paper discussed the key factors influen- cing the differences of power curve and annual energy production.
