  4. 2. Modelling and Experimental Verification of Direct Drive Wave Energy Conversion : Buoy-Generator Dynamics

    Author : Mikael Eriksson; Mats Leijon; Jan Isberg; Arne Wolfbrandt; Kim Nielsen; Uppsala universitet; []
    Keywords : Engineering physics; Wave energy; Potential wave theory; Linear generator; Simulations; Experiments; Point absorber; FEM; Equivalent circuit theory; Teknisk fysik; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : This thesis is focused on development of models and modelling of a wave energy converter in operation. Through the thesis linear potential wave theory has been used to describe the wave-buoy interaction. The differences lie in the generator models, in the simplest model the generator is a mechanical damper characterized by a damping factor. READ MORE
