Abstract
A wave power generator with an impulse turbine is installed in the breakwater and consists of the air-chamber,turbine,generator and safety devices.The purposes of this paper are to construct the design method.As for the motion of water inside the air-chamber,that is,oscillating water column(OWC) is solved by the eigenfunction expansion method.The characteristics of turbine and OWC for irregular wave are solved by assuming the Gaussian distribution for the probability density of the flow rate of turbine.The time average turbine outputs are calculated by setting the limit of the rated power of an electric generator.The initial design decides the turbine size,the rotational speed and the rated generator power from calculation results for the several wave conditions.
