Abstract

A wave energy conversion system comprising a wave energy absorber, a power take off (PTO), a sensor and a controller for determining a force at the PTO in response to a sensed operating parameter of the wave energy absorber and dynamically varying at least one of the operating parameters to provide the required PTO force so as to either reduce or reach parametric resonance. In the arrangement configured to reach parametric resonance the wave energy absorber also has a variable water piercing area (Fig 17). The operating parameter varied by the controller may be the metacentric height, centre of gravity or displacement of the absorber or the pretension, width or stiffness of the mooring of the absorber. The controller may include an adaptive filter such as a notch band-stop filter with parameters which change according to the wave conditions and applied to a signal representing the force acting on the PTO.
