Reactive Control System for Swelll Wave Energy Convertor

Abstract

Wave energy converters are devices designed to harness the power of ocean waves and convert it into usable electricity. These converters are essential because they provide a reliable and consistent source of renewable energy, unlike some other renewable sources like solar or wind, which can be intermittent. This predictability makes wave energy converters a reliable source of power generation, providing stability to the energy grid.

Wave energy from swell waves has garnered significant attention as a promising source of renewable energy. Swell waves are ocean wave that originates from distant storms and carries a substantial amount of energy. The potential of wave energy from swell waves lies in its consistency and capability to generate power regardless of the weather conditions. This sets it apart from other renewable sources and makes it a valuable addition to the renewable energy mix.

A patented swell wave energy converter Power take off (SWEC PTO) by Ocean Energies AS holds great promise in harnessing the energy of swell waves. With its innovative design, this converter has the potential to revolutionize the wave energy industry by efficiently capturing the power of swell waves.

The objective of this thesis is to define a model for 30-meter diameter floater and investigate the hydrodynamic forces acting on it under swell waves of defined wave height and time period. These forces are intended to be utilized as a driving mechanism for the SWEC PTO. Subsequently, a reactive control strategy will be formulated using a flywheel with twin clutch system to enable efficient transmission of power from the floater to the tri-crank system of the PTO and further to a Generator input.
