摘　　要：本文在经过验证的Quoddy Region海域三维潮流数值模型的基础上,植入了提取潮流能的数值计算模块。确定了Western Passage在3种涡轮机布设方式下能够提取的能量以及提取能量的效率,其中采取3排涡轮机交叉布设的方式时,1个大小潮时间内提取的能量最高,可达1 148.1MWh,提取效率为4.57%,远高于另外2种方式。在单排涡轮机布设的实验中(实验一),通过改变速度衰减系数,得到了可提取能量随速度衰减系数的变化曲线,该曲线与前人在理论分析时得到的曲线类似。同时本文还分析了提取潮流能给周围流场带来的影响。This study is based on a coastal ocean model for Quoddy Region whose results are validated well with observations. Turbines are implemented in the regional ocean circulation model. The energy extraction quantities and efficiencies across Western Passage for three different types of turbine arrangements are determined. Over one spring-neap cycle, the third type of arrangement with lattice form can harvest most energy 1148.1 MWh with extraction efficiency 4. 57% which is much higher than the others. A power curve is determined for different values of flow blockage in case 1, the asymmetry Of the curve is similar to the one shown in previous theoretical study. Meanwhile the effects on tidal current by extracting energy are evaluated.
