| Summary: | The research of potential tidal kinetic energy calculation has been carried in Toyapakeh
Strait, Bali, Indonesia. Current dynamics simulated using Delft3D-Flow hydrodynamic model with
8 tidal constituents (M2, S2, K1, O1, N2, K2, P1, and Q1) from TPXO 7.2 Satelite with assumption
vertical speed is the same (2D). Bathymetry data was taken from GEBCO (General Bathymetric
Chart of The Ocean) combined with BIG (Badan Informasi Geospasial) and P3GL (Pusat
Penelitian dan Pengembangan Geologi Kelautan) field measurement in 2015. The model was run
for a period of 25 days (August 10th – September 3th). Then, we calculated potential of kinetic
energy using Fraenkel equation and Gorlov Helical Turbine’s performance that can produce
electrical power from ocean current with minimum speed (cut-in speed) of 0.5 m/s. The result of
simulation shows that total electrical power potential in one tide cycle reach its maximum value
in the Point B (8.7° S - 115.4633° E), it reachs 144.614 kW in spring tide and 31.433 kW in neap
tide. Under simulation turbine can produced electrical power for 12 days with total electrical
power reaches 986.882 kW. These electrical powers are produced by using Gorlov Helical Turbine
with 0.6 m diameter and 0.86 m height. |
