Abstract

 The power potential of tidal currents around Nagashima Strait were examined in relation to tidal current power generation using the results of ADCP observation and numerical simulation. We found the tidal current power of 2.2 kW/m2 in the Nagashima Strait and 6.0 kW/m2 in the Kuronoseto Strait. Moreover, it was shown from the results of the numerical simulation for the arrayed 20 tidal current turbines that the daily mean value of extractable tidal energy is 447 MW in the Nagashima Strait and 540 MW in the Kuronoseto Strait. In addition, it was suggested that the amplitudes of tidal currents in the Nagashima Strait and the Kuronoseto Strait decrease 6 cm/s and 11 cm/s, respectively, because of the arrayed turbines.
