Abstract [en]

The division of Electricity at Uppsala University is developing a wave energy converter(WEC) consisting of a linear generator connected to a bouy at the water surfacethrough a wire cable called the connection line.During extreme conditions, the wave power plant will experience forces up to 500kN, which lead to unnecessary wear and will ultimately cause the failure of theconverter. To prevent this there is a need for a damper.The wave energy converter works at a maximum efficiency when the translator’sare centered with respect to the stator. Due to tidal movements the position of thetranslator can deviate. There for a mechanical divice that will compensate for this isneeded.This report describes the further development of an earlier project where a tidalwave compensator for a wave energy converter of Seabased AB was developed. Thecompensator Mattias Maier developed in the earlier project needed a locking systemto lock thecompensators position when not active. This report also illustrates the developmentof a damperthat is to be implemented in the WEC. The damper´s function is toprevent peak forces to occurring. This has to be achiveble without lowering thepower plant’s efficiency, meaning that it should only start to moderate the force whenit goes above 200 kN.The design process consisted in developing and dimensioning twosolutions, with special consideration to the standard components and manufacturingmethods available at the workshop in Lysekil.The project resulted in 3D modeled design solutions and complete manufacturingdrawings. We also present some recommendations for further studies in chapter 8.
