论文摘要
动态风电场控制是一种新策略,旨在在上游风力涡轮机上应用时间变化的,通常是周期性的控制信号,以增加涡轮机后面的唤醒混合。结果,唤醒恢复是加速的,导致下游涡轮机的功率更高。随着风力发电场中风力涡轮机的动态控制策略的兴趣正在增加,提出了不同的方法。一种这种新颖的方法称为动态个体音高控制(DIPC)。在DIPC中,涡轮机的每个叶片螺距角都可以独立控制,以动态操纵施加在风在风的推力矢量的方向。因此,唤醒的方向变化,诱导唤醒混合,而没有明显的推力幅度变化。在本文中,使用大型涡模拟(LES)实验评估了推力方向上不同变化的有效性。
Dynamic wind farm control is a new strategy that aims to apply time-varying, often periodic, control signals on upstream wind turbines to increase the wake mixing behind the turbine. As a result, wake recovery is accelerated, leading to a higher power production of downstream turbines. As the amount of interest in dynamic control strategies for wind turbines in a wind farm is increasing, different approaches are being proposed. One such novel approach is called Dynamic Individual Pitch Control (DIPC). In DIPC, each blade pitch angle of a turbine is controlled independently to dynamically manipulate the direction of the thrust force vector exerted on the wind. Hence, the direction of the wake is varied, inducing wake mixing without significant thrust force magnitude variations on the rotor. In this paper, the effectiveness of different variations in the thrust direction are evaluated and compared using Large Eddy Simulation (LES) experiments.
