Project Neptune: Critical Component Tests for a Fully Flooded Direct-Drive Linear Generator for Wave Energy Convertors

Abstract

A significant challenge for Wave Energy Convertor (WEC) designers and manufacturers is the efficient conversion of differing wave types into useful motion to produce electricity. The height, period and orientation of waves vary greatly as do their respective power levels [1]. In order to efficiently and cost effectively convert the kinetic energy of wave motion into electrical energy, a Power Take Off (PTO) system must be able to withstand the harsh environment of the offshore marine environment, provide efficient energy extraction over various wave load states whilst maintaining low O&M costs over a long life span [2].
