碩士 / 國立臺灣海洋大學 / 河海工程學系 / 103 / Taiwan is surrounded by the sea and has been continually advocating developing and utilizing ocean power. Approximately 99% of Taiwan’s electrical power depends on imports. Under the premise of obtaining electrical power in a manner that is environmentally friendly, clean, and safe for Taiwan’s environment, ocean current power is a green energy alternative to solar and wind power. Developing and utilizing ocean current power requires first assessing its potential and value. According to the Industrial Technology Research Institute’s simulation of the near-coast ocean areas around Taiwan, the strong currents concentrated in Taiwan’s northern ocean areas would be beneficial for generating ocean current power. Therefore, this study conducted observations of tides, waves, and ocean currents in the ocean area near Linshanbi. The field measurement data provided the calibration parameters for a Numerical module, further simulating the flow-field distribution characteristics of the ocean area near Linshanbi, from which an advantageous position and orientation were proposed for establishing an ocean-current power station. The results of a hydrodynamic model revealed that the maximal flow rate in the isobaths at -20 ~ -50 m depths off the Linshanbi coast is approximately 2.27 m/s, with a mean flow rate of 1.62-0.94 m/s in a principally northeast–southwest direction. Furthermore, the field observation data were compared to the model calculation results, and a formula was employed to convert the flow rate into ocean-current power generation potential. The generation potential was concentrated among the coordinates (E°121.47274,N°25.30460) and coordinates (E°121.49665,N°25.32438) with 5.3-km2 rectangular area.
