Abstract

The paper presents the design procedure and the modeling of performance for a special four sided linear permanent magnet generator, used in sea wave energy extraction applications. In order to efficiently exploit the wave energy through a floating buoy, it is important to tune its movement with the main frequency of the wave by using appropriate control. This leads to limited duration saturation of the generator and the system analysis requires particularly developed electromagnetic – mechanical – hydraulic models. The saturation effects under this operational condition were studied, while the dynamic variations of the respective operational parameters of the machine were estimated..
