Abstract
One of the main advantages of ocean waves as resource for electrical energy production is its high energy density. Several methods have been proposed for the conversion of ocean wave mechanical energy into electrical energy. One such method consists in the use of a direct drive linear generator enclosed inside a floating element. The generator is driven by a mass-spring system, which oscillates due to the ocean wave’s movement. In this paper are presented the study, development, and dynamic simulation of a linear tubular synchronous low speed permanent magnet generator, for use in a wave energy conversion system. The generator was dimensioned using a finite element analysis tool. The wave energy converter dynamic model, mechanical and electrical, was developed to evaluate its response. To validate the generator’s dimensioning and dynamic model, its prototype was built. The dynamic model simulation results and the prototype’s experimental results are presented.
