A wave power generation system includes: a hydraulic pump device configured to operate by force of a wave to discharge an operating liquid to a main passage; a hydraulic motor device configured to be rotated by the operating liquid flowing through the main passage; a power generator configured to be driven by the hydraulic motor to generate electric power; and a heat exchanger device configured to perform heat exchange of the operating liquid. The heat exchanger device includes a heat exchange motor device connected to the main passage through a sub passage and configured to be operated by the operating liquid introduced through the sub passage, a refrigerant pump device driven by the heat exchange motor device and configured to suck and discharge a refrigerant liquid, and a heat exchanger to which the refrigerant liquid discharged from the heat exchange pump device and the operating liquid are introduced.

Wave power generation system

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.
