本文的目的是提出一个半解析模型，旨在通过最大化机械发电量来优化潮汐能场布局。采用一种元启发式方法来寻找涡轮间流动相互作用最小的位置。用解析模型模拟了涡轮尾迹的速度。该方法首先应用于理想化的情况：恒定的电流大小和方向，以及与涡轮机对齐的流量。这些初步试验允许检验结果的一致性。特别是，它们表明，器件的最佳密度随着湍流强度或上游速度大小的增加而增加。然后将该方法应用于位于Alderney Race（法语为Raz Blanchard）的场地，该场地位于Alderney岛和La Hague Cape（法国）之间。结果表明，最优布局受潮流不对称性的影响，最优布局强烈依赖于潮流相对于主导方向的方向扩展。
The purpose of this paper is to present a semi-analytic model designed to optimize tidal farm layouts by maximizing the mechanical power production. A meta-heuristics method is used to find the turbine placement which minimizes the flow interaction between the turbines. The velocities in the wakes of turbines are simulated with an analytic model. The methodology is first applied to idealized cases: constant current magnitude and direction, and flow aligned with the turbines. Those preliminary tests permit to test the consistency of the results. In particular, they show that the optimal density of the devices grows with increasing turbulent intensities or increasing upstream velocity magnitude. The methodology is then applied to a site located in the Alderney Race (Raz Blanchard in French), situated between the Alderney Island and La Hague Cape (France). The results show that the optimal placement is influenced by the asymmetry of the tidal current and that the best layout is strongly dependent on the directional spreading of the current with respect to the predominant direction.
