本文通过现场实验证明了通过减少上游风力涡轮机来最大限度地减少尾流效应以提高风电场产量的潜力。SMV（Le Sole de Moulin Vieux）风电场的两台2 MW涡轮机用于此目的。该农场配备了最先进的激光雷达（光探测和测距），用于测量风的特性，频率高达1 Hz。使用WindPRO进行尾流效应预测的模拟。模拟优化的削减策略，以找到上游涡轮机的最佳削减设置。基于真实的时间数据的结果与模拟结果进行了比较。结果发现，模拟大多是在良好的协议与现场的结果，最大的差异为1.5%。分析表明，通过将上游涡轮机的功率减少约17%，使用硬削减策略，在下游涡轮机生产中可能获得高达11.5%的增益。在该实验中，两个涡轮机的组合产量随着硬削减策略而降低，这表明上游涡轮机必须被最佳地削减以避免任何产量损失。据作者所知，这是第一次在运行的风电场中实际实施基于LiDAR的协调控制策略。
This paper demonstrates, with live field experiment, the potential of increasing wind farm production through minimising wake effects by curtailing upstream wind turbines. Two 2 MW turbines from the SMV (Le Sole de Moulin Vieux) wind farm are used for this purpose. The farm is equipped with state of the art LiDARs (Light Detection And Ranging) for measuring wind characteristics, up to a frequency of 1 Hz. Simulations are performed usingWindPRO for wake effects prediction. Optimised curtailment strategies are simulated for finding optimum curtailment settings of the upstream turbine. Results based on real time data are compared with simulated results. It is found that simulations are mostly in good agreement with field results, with a maximum difference of 1.5%. Analysis shows that a gain of up to 11.5% is possible in downstream turbine production, using a hard curtailment strategy by reducing power of the upstream turbine by about 17%. In this experiment, the combined production of the two turbines decreased with the hard curtailment strategy, indicating that the upstream turbine must be optimally curtailed for avoiding any production loss. To the best knowledge of the authors, this is the first practical implementation of LiDAR based coordinated control strategies in an operating wind farm.
