摘要:
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. The invention is characterised in that the electrical generator supplies electrical power to a power grid, which is averaged over a plurality of flow oscillation periods using a generator side converter, an direct current link and a network side converter, wherein an electrical energy storage (14) is connected to the direct current link by means of a DC converter; the voltage value of the direct current link is maintained between a lower limiting voltage and an upper limiting voltage by a closed-loop and/or open-loop control of the power input and the power output and the air turbine is speed guided, depending on a variable, which characterises the flow in the flow channel and/or the pressure in the wave chamber.

The invention concerns a method for the operation of an underwater power plant witha water turbine to take up kinetic energy from a surrounding flow; andan electrical generator coupled directly to the water turbine; characterized in thatthe power regulation in the generator mode is done by a control or regulation of the load moment produced by the electrical generator for a freely adjusting rpm speed of the water turbine,wherein the setpoint value of the load moment in a first, power-optimized operating range is established by a state controller and/or a search mechanism for the power maximum; andin a second, power-limited operating range the assigned load moment is chosen so that an operating point distant from the power optimum results for the water turbine.
