Method for Operating a Wave Energy Converter for Converting Energy from a Wave Motion of a Fluid into another Form of Energy
First Claim
1. A method for operating a wave energy converter configured to convert energy from a wave motion of a fluid into another form of energy, wherein the wave energy converter has (i) a lever arm mounted so as to be rotatable about a rotor rotational axis and including a coupling body, and (ii) an energy converter coupled to the rotatably mounted lever arm, the method comprising:
- controlling a rotational speed of the lever arm about the rotor rotational axis such that the rotational speed of the lever arm, averaged over time over one revolution, corresponds to an orbital speed of the wave motion; and
controlling the rotational speed of the lever arm such that an angle between a tangential speed of the coupling body and of a local flow rate of the wave motion about the coupling body deviates by a predefinable value that is less than or equal to 90°

Abstract
A method for operating a wave energy converter for converting energy from a wave motion of a fluid into another form of energy, wherein the wave energy converter has a lever arm, which is mounted so as to be rotatable about a rotor rotational axis and bears a coupling body and an energy converter which is coupled to the rotatably mounted lever arm, includes controlling a rotational speed of the lever arm about the rotor rotational axis such that, averaged over time over one revolution, it corresponds to an orbital speed of the wave motion, and controlling the rotational speed of the lever arm such that an angle between a tangential speed of the coupling body and of a local flow rate of the wave motion about the coupling body deviates at maximum by a predefinable value of 90°.
