Abstract
A wave power generation system includes a wave receiving member, ram cylinder hydraulic pump device, change value sensor, accumulator device, hydraulic motor, power generator, and controller. The member is arranged near a virtual reflection surface that reflects a coming incident wave. The controller sets a torque command used when the generator generates electric power. Based on a differential value of a change value detected by the sensor and changes in accordance with a swing amount of the member, the controller determines whether the member is swinging toward a first or second side in a swing direction. When the controller determines the member is swinging toward the second side by receiving force of a reflected wave reflected by the virtual reflection surface, the controller changes the torque command from the command set when the controller determines the member is swinging toward the first side by receiving force of the incident wave.
