CHARACTERISTICS OF HEAVE & PITCH BUOY TYPE WAVE ENERGY CONVERTER SYSTEM

Abstract

We proposed small sized wave energy converter system named Heave & Pitch Buoy Wave energy converter system (HPB) using two rotary vane pumps to applying for 5-10kw class, which will be adapted to set at T=4-6sec, 4.5m sea depth for personal use and energy-supply for developing project of deep sea water. It has been developing by demand of economical market study of Center of Business Creation of OTARU Univ. of Commerce. In this paper, we examined the characteristics of this HPB to use 1/15 scale model subjected wave channel by using parameters: T, pump torque, wave height. This HPB system has 2 rotary vane pumps for getting Heave and pitch energy individually. In these experimental parameters, we observed that energy efficiency of HPB system was about 63% maximum.
