Abstract: A method for operating a wave power plant, where the method supplying, using a electrical generator, electrical power to a power grid, which is averaged over a plurality of flow oscillation periods using a generator side converter, a direct current link and a network side converter, where an electrical energy storage is connected to the direct current link using a DC converter, and maintaining the voltage value of the direct current link between a lower limiting voltage and an upper limiting voltage by at least one of a closed-loop and an open-loop control of a power input and a power output, wherein an air turbine is speed guided, depending on a variable, which characterises the flow in at least one of the flow channel and the pressure in the wave chamber, wherein the rotational speed is guided continuously during a flow oscillation period.

Abstract: A turbine system for the utilization of the energy of oceanic waves includes: a chamber that is provided with an opening at its lower end and at its upper end respectively; a duct that is open at both ends for guiding a stream of air, the lower end of the chamber being designated to be submerged in ocean water, and the opening of the upper end being connected with one of the ends of the duct; an energy unit that is mounted coaxial to such and surrounded by the duct; and a device for cleaning the rotor blades of deposits or for preventing the formation of deposits on the rotor blades.

Abstract: The invention concerns a method for operating a wave power station comrising a wave chamber, which communicates with a flow channel leading to the exterior, wherein an oscillating air current is generated by the wave movement inside the wave chamber; an air turbine rotating in a single direction for an incident airflow coming from opposite directions, wherein said turbine is arranged in the flow channel and drives at least indirectly an electrical generator.
