Abstract

This paper presents performance optimization studies on a linear generator wave energy converting system developed by Uppsala University of Sweden. The optimization is focused on the investigation of the power absorption with regard to the wave climate at the Lysekil test site for the developed wave energy converter. A frequency domain simplified numerical model is built based on the equation of motion of the system for simulating the behavior of the wave energy converter. The power take-off damping coefficient is chosen as the control parameter in this study. The result shows that the power take-off damping coefficient can be further optimized with regard to the characteristic of the wave climate at the test site for increasing the power absorption capacity of the linear generator wave energy converter. This study will provide significant performance optimization information to the development of the linear generator wave energy converting technology.
