This paper presents an innovative modeling technique that combines experimental force measurements from a full scale linear generator with a coupled model of a two body, moored floating system to investigate the performance of a wave energy conversion system. An experiment was conducted using the Oregon State University’s wave energy linear test bed to characterize the frictional and electromagnetic forces generated by the SeaBeavI linear generator. These force characteristics have been incorporated into a coupled model using a numerical fluid-structure interaction model, OrcaFlex, to predict the energy extraction potential of the system.

This paper presents an innovative technique for evaluating the performance of direct-drive power take-off systems for wave energy devices using simulated force and velocity profiles. The performance of a linear generator was evaluated in a realistic operating condition using the results from a coupled model of a taut moored, dual body, and wave energy conversion system as position input for Oregon State University’s wave energy linear test bed. The experimental results from the linear test bed can be compared with the predictions of the simulation and used to evaluate the efficiency of the generator.
