Abstract
This work presents a procedure for the design and analysis of a linear tubular switched reluctance generator for wave energy conversion. The generator is meant to be applied to a direct drive wave energy converter, namely a point absorber. The device is modeled according to wave climate conditions at Esposende site in the Portuguese coast. The procedure starts with statistical analysis of the local random ocean behavior in order to determine most likely values of occurrence for the wave parameters in question. Based on that, the generator is analytically designed. With the proper dimensions calculated, a numerical simulation is performed and the magnetic flux path and density values are determined.
