PROBLEM TO BE SOLVED: To provide a wave power generator that takes out energy from wave to perform generation, and can prevent failure or the like of the wave power generator at heavy weather, and to provide a control method of the wave power generator.SOLUTION: In a wave power generator 1 including a body 3, a power generation buoy 2 vertically moving along the body 3, and a power generation mechanism, the power generation buoy 2 includes a buoy body 21, and an expansion body 22 fixed to the buoy body 21 and filled with gas A therein. The wave power generator 1 discharges the gas A in the expansion body 22 to the outside at heavy weather, and performs heavy weather control that sinks the power generation buoy 2 under the sea surface. |
