基于SCADA数据的陆上风机尾流评价

Wake Evaluation of Onshore Wind Turbines Based on SCADA Data

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15.0m/s≤v<25.0m/s范围内,机组B平均功率损失率为9.3%;风速10.9m/s≤v<15.0m/s范围内,机组B平均功率损失率为24.7%;风速3.0m/s≤v<10.9m/s范围内,机组B平均功率损失率为84.4%。

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 was9.3%;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%.
