Abstract
A wave power generator with an impulse turbine is installed in the breakwater and consists of the air-chamber, the turbine, the generator and the 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, the 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 friction loss torque is considered by the simple assumption for the turbine and generator. An initial design decides the turbine size, the rotational speed and the rated generator power from calculation results for the several wave conditions.
