碩士 / 國立成功大學 / 海洋科技與事務研究所 / 101 / The POM (Princeton Ocean Modeling) model was applied for simulating ocean current around Taiwan coastal waters. The nested domain was adopted to narrow down the computational region and increase numerical accuracy to the southeast waters of Green Island at Taiwan. A higher-resolution layer with a spatial grid of 500m (1/200 degree) was constructed to simulate the distribution of ocean current and related velocity in the Green Island.GIS (Geographic Information Systems) spatial analysis was also employed to evaluate and select a proper ocean current power site. The refined Green Island current model had been validated using comprehensive date of measured tidal currents. Numerical results indicated that ocean current power was relatively strong in the following areas: the Kuroshio area, the Penghu coastal area, and the coastal waters away from the southern tips of Taiwan. The Kuroshio is a steady steady and uniform flow with a large amount of flow discharge.
The Green Island is located in the southeast of Taiwan with bridges to have shallow water depth which produces a higher speed as Kuroshio travels along the Island. This enables the higher possibility to construct ocean current poewr energy station for mooring system problems. In this papers, we first investigated the current field using numerical simulation by POM model. Velocity field at different water depths were also presented to ensure that turbine can still work in a deep water depth during typhoon events. Based on the current speed distribution analysis, we use GIS to help for selecting an appropriate site to construct a ocean current power station.
