 Tidalpower has a potential for future electricity generation same as wind energyand solar energy. Difference is that tidal energy is more stable and predictable than wind energyand solar power. Among sources ofrenewable energy, tidal power has beentreated as a systemwith highcost and limited sites where we can find sufficiently high tidal energy. However, many recent technological developments improve its profitabilityby using these advantages compared with other renewable energies. To obtain the maximumefficiencyoftidal turbine, the conventional blade element momentum method (BEM) has been used and manycorrectionfactors were developed. Inthis paper, calculation methods whichhave been used inthe area of marine propellers are applied tothe designoftidal turbines and evaluated indetail based oncomparison withthe conventional BEM used in wind turbine field.
