摘　　要：针对风电场平均风速的时距取值与风电机组出力对风速的实际响应时间不匹配的问题,基于风机功率曲线、风电场风速测量及风电机组出力特性,分析了风电场测风频率与风机出力特性的匹配程度及不同的平均风速时距取值对风电场出力计算结果的影响,提出了平均风速时距合理取值的建议。In order to solve the problem that the selection value of average wind speed time interval of wind farm is not matched with the actual response time of wind power output, based on wind power curve, wind speed measurement and characteristics of wind power output, this paper not only analyzes the matching degree between the frequency of wind speed measurement and the characteristics of wind power output but also studies the impact of different average wind speed time intervals on wind power output. Finally, the suggestion of reasonable average wind speed time interval is given.
