本文建立了风电场风流的动态模型。该模型基于线性纳维-斯托克斯方程的空间离散结合涡柱理论。采用有限差分法对模型进行空间离散，提供了动态风电场模型的状态空间形式。该模型提供了风电场中流动行为的近似值，并获得每个风力涡轮机附近的风速。随后，利用荷兰能源研究中心位于荷兰维灵格梅尔的风力涡轮机试验场的测量数据以及另外两个风流模型的结果对该模型进行了验证。这项工作的最终目标是通过常微分方程提出风电场流量模型，应用于风电场控制算法以及负载和功率优化。版权所有 © 2013 约翰·威利父子有限公司
A dynamic model for the wind flow in wind farms is developed in this paper. The model is based on the spatial discretization of the linearized Navier–Stokes equation combined with the vortex cylinder theory. The spatial discretization of the model is performed using the finite difference method, which provides the state-space form of the dynamic wind farm model. The model provides an approximation of the behavior of the flow in the wind farm and obtains the wind speed in the vicinity of each wind turbine. Afterwards, the model is validated using measurement data of Energy research Center of the Netherlands’ Wind turbine Test site in Wieringermeer in the Netherlands and by employing the outcomes of two other wind flow models. The end goal of this work is to present the wind farm flow model by ordinary differential equations, to be applied in wind farm control algorithms along with load and power optimizations.
