The ocean currents off Florida are a renewable and energy dense resource capable of providing Florida with about 25% of its electricity needs. This current is strongest at the sea surface and decreases in strength with depth such that the individual rotor blades on ocean current turbines (OCT) deployed to harness this resource will operate in stronger currents when positioned vertically upwards than when vertically downwards. This current shear will induce cyclic loadings on the rotor blades...
Show moreThe ocean currents off Florida are a renewable and energy dense resource capable of providing Florida with about 25% of its electricity needs. This current is strongest at the sea surface and decreases in strength with depth such that the individual rotor blades on ocean current turbines (OCT) deployed to harness this resource will operate in stronger currents when positioned vertically upwards than when vertically downwards. This current shear will induce cyclic loadings on the rotor blades unless active control is used to reduce these load variations. A direct adaptive individual blade pitch controller is implemented into a numerical model simulating an OCT operating in the Gulf Stream. The adaptive controller is analyzed with the OCT simulated in both stationary and moored configurations. The results concluded that the IBP controller reduced the amplitude of the loads in the stationary and moored simulations by 91.18% and 92.3%, respectively.
