为考察水轮机阵列对区域潮流特性的影响,本文基于Delft 3D-Flow建立斋堂岛及附近水域的三维水力学模型并通过实测数据进行校验。经验证后的模型,采用TSE方法确定阵列在目标水域中的放置位置,并通过动量损失方式模拟水轮机对流场的影响,进而研究和评估在一定水域面积下不同水轮机数量组成的阵列对潮流场的影响。仿真结果显示:该水域放置水轮机阵列将对附近较大范围水域的水位产生影响,在靠近阵列处水位变化最大能达到3 cm;对区域流速影响较为显著,当阵列中水轮机密度较大时,其尾流影响区域局部时刻流速下降能达到45 cm/s且影响距离可延伸至其下游2 km外。
Abstract：In order to study influence of tidal turbine array on the regional tidal regime, a three-dimensional hydrodynamic model of Zhaitang Island and its adjacent waters was built by using the FLOW module of the software Delft3 D, accuracy of which was verified with in-situ measured data. After verification, the TSE(Tidal Stream Exploitability) method, a tool developed to facilitate the selection site method of tidal power sites in depth-limited zones, was applied to select the location of setting turbine array, and the impact to the waters due to the operation of a turbine was emulated by adding a momentum loss term in the equations of the model. Then, the impacts on tidal current field induced by the arrays with different numbers of turbines in waters of a unit area could be studied and assessed. According to the simulation results, the placement of the turbine array in the waters would affect the water level of the nearby large-scale waters, and the maximum water level change could reach 3 cm near the array; however, the influence on tidal velocity is relatively visible, the drop of flow velocity could reach 45 cm/s in the wake and the influenced area would reach 10 km downstream when turbines intensively deployed.
