WAVE POWER GENERATION SYSTEM

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