Abstract
Rational exploitation of wave energy makes great contribution to relief the current global energy crisis. Power generation has been taken into the agenda as the main form to utilize wave energy. The point absorber in this paper is simplified to three modules: floater, pontoon and chain. Based on the theory of linear regular wave, the research task of the point absorber is to improve the conversion efficiency and device reliability. This paper researched on the double floater wave energy converter by hydrodynamic numerical calculation, studied the factors that contain the PTO system damping coefficient, wave frequency and the device mass and other factor which can influence the energy conversion efficiency. At last, we found an optimized method for the energy conversion efficiency.
