International ClassF03B 013/24Foreign Application Priority Data1988-10-21 JPAbstractA wave power generating system for generating electricity using natural wave power, includes wave energy converters for converting wave energy into air pressure, a constant air pressure tank for storing the air pressure from the wave energy converters to equalize the fluctuation of the air pressure, an air turbine stationarily driven by the equalized air pressure, and an electric generator for generating stable electricity using the rotating power of the air turbine. The wave energy converters are settled to the bottom of the sea and are sufficiently tall to function as wave dissipation facilities. The air pressure in the constant air pressure tank is automatically controlled toward a target value by a controller and the target value is calculated by the controller in accordance with measured values of wave amplitude and period and the current air pressure of the constant air pressure tank. The wave power generating system can operate at the most efficiency when the air pressure in the constant air pressure tank is set to the target value. | |
