摘　　要：本文介绍了变速恒频风电机组的基本运行机理，并采用统计学的方法分析了风电场SCADA中风电机组的实测运行数据，在分析结果的基础上重新建立了适用于风电机组仿真分析的风速-功率特性曲线。验证计算结果证明根据实测运行数据建立的风速-功率特性曲线更接近于风电机组实际的运行情况，在变速恒频风电机组仿真分析的建立过程中，采用新风速功率特性曲线能显著提高分析的精确性。This paper briefly reviewed the operation principle of VSCF wind turbine. Based on the real operation data of wind turbines obtained from the SCADA, the Vw-Pe characteristic curve has been built in a statistical way. It is different from the curve provided by the manufacturer. Simulation results show that the new curve is accurate to reflect the relationship between Vw and Pe. Adoption of the new Vw-Pe curve in the modeling of VSCF wind turbine can improve the simulating precision obviously.
