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.
