摘　　要：在分析常规风电机组出力特性评价方法的基础上,探讨了评价过程中存在的诸多问题。介绍了一种通过实时/历史数据库获取风电场相关生产数据,并将所得数据换算成标准条件下的环境工况值,进行实时在线计算。通过自动绘制风电机组风速-电功率的特性曲线,结合标定的额定设计值,对实际运行结果数据进行离散度偏差比较,从而实时监测和评价风电机组在某段时间内和当前时期内的运行性能。On the basis of analyzing the conventional methods for wind turbine output performance evalua- tion,several problems occurred during the evaluation were discussed. Then, a method evaluating the per- formance of wind turbine was presented, which acquires relevant production data of wind farm through real-time/historical database and then converts the data into standard conditions values. By online calculation,the characteristic curves of the turbine electrical output power and wind speed will be drew automati- cally. Combing with the rated design calibration values, the deviation of discrete degree of the actual operation data was compared, thus the staff can supervise and evaluate the operation performance of the units in a certain period and the current period.
