摘要： 基于风电场的SCADA 数据，在北偏东0°~ 90°范围内，以不受尾流影响的前排机组A 为参照，对后排机组B
的实测风速和发电功率进行分析。研究发现：在北偏东风向上，位于下风向的机组B 遭受前排机组A 的尾流影响；风速
15.0 m/s ≤ v < 25.0 m/s 范围内，机组B 平均功率损失率为9.3%；风速10.9 m/s ≤ v < 15.0 m/s 范围内，机组B 平均功率
损失率为24.7%；风速3.0 m/s ≤ v < 10.9 m/s范围内，机组B 平均功率损失率为84.4%。

Abstract: This paper analyzed the SCADA data of the actual measured wind speed and power generation of the rear wind turbine
B within the range of 0°- 90°east to the north, using the front wind turbine A that is not affected by wake as a reference. The
results showed that the wind turbine B, which was in the downwind direction, was affected by the wake of the upstream wind
turbine A; when wind speed was in the range of 15.0 m/s ≤ v < 25.0 m/s, the average power deficit rate of the wind turbine B was
9.3%; when wind speed was in the range of 10.9 m/s ≤ v < 15.0 m/s, the average power deficit rate of the wind turbine B was 24.7%;
when wind speed was in the range of 3.0 m/s ≤ v < 10.9 m/s, the average power deficit rate of the wind turbine B was 84.4%.
