摘要：

采用Mike21构建并验证三沙湾海域高分辨率潮流动力模型，根据模拟结果分析该海域流速以及能流密度分布，选定东冲水道和三都澳口两处潮流能资源密集海域开展评估，结合有效发电小时数、可利用小时数及水深确定两处海域内潮流能开发的适宜位置，并采用Farm方法和Flux方法对潜在开发区域进行资源可开发量评估。结果表明：东冲水道和三都澳口年平均能流密度最大值分别约为1.0和0.6。Farm方法计算东冲水道和三都澳口潮流能资源可开发量分别为5.74 MW和7.49 MW;Flux方法计算得两处资源可开发量分别为4.28～4.64 MW和1.20～3.14 MW。

A high-resolution tidal current model of Sansha Bay was developed and validated using MIKE21. Model results were used to analyze the spatial distribution of current velocity and energy flux density, leading to the identification of two resource-concentrated sites: the Dongchong Channel and the Sandu'ao entrance. Considering effective generating hours, available hours, and water depth, suitable locations for tidal energy exploitation were determined. Resource assessments based on the Farm and Flux methods show that the Dongchong Channel and Sandu'ao entrance have maximum annual mean energy flux densities of approximately 1.0 kW/m² and 0.6 kW/m², respectively. The Farm method estimates exploitable tidal energy resources of 5.74 MW and 7.49 MW, while the Flux method yields 4.28～4.64 MW and 1.20～3.14 MW for the two areas, respectively.
