潮流能水轮机阵列水动力与布局优化研究进展

概述了潮流能水轮机阵列的水动力特性,总结了不同横向、纵向间距下水轮机尾流变化的一般规律,梳理了水轮机阵列布局的优化方法,从人工传统优化阵列布局与计算机自动优化阵列布局两方面回顾了水轮机阵列单目标优化与多目标优化的研究进展。人工传统布局结构简单且易于操作,有比较强的工程实践性,但物理试验可限制的约束条件有限,难以模拟阵列在真实海况下的发电情况；自动优化布局相比于人工传统布局更具有现实意义,但依然面临经济模块因素缺乏、多目标内容待完善、理论与实践未统一、前期准备时间较长等诸多挑战。

Research progress on hydrodynamics and layout optimization of tidal stream turbine array

The article explores the hydrodynamic characteristics of turbine arrays, summarized the general rules of changes in the wake of turbines with different horizontal and longitudinal spacing, combs the optimization methods of turbine array layout, and reviews the research progress of single-objective optimization and multi-objective optimization of turbine array layout from two aspects of artificial traditional optimization of array layout and computer automatic optimization of array layout. The artificial traditional layout structure is simple and easy to operate, and more practical in engineering, while the constraints of physical tests are limited, and it is difficult to simulate the power generation of turbine array in real sea conditions; compared with the traditional layout, the automatic optimization has more practical significance, but it still faces many challenges, such as the lack of economic module factors and the multi-objective, inconsistent theory and practice, and long preparation time.
