摘要:
A gyrating wave power plant, comprising a body (1) floating on water with a main plane which in calm water is substantially vertical. The body is moored in an orientation with the main plane transverse to the propagation direction of waves. The body has its upper and lower sections provided with arched fins (2, 3). The fins (2) in the body's upper section curve downward when proceeding towards side edges of the body, and the fins (3) in the body's lower section curve upward when proceeding towards side edges of the body. The arched shape of the fins (2, 3) is an oval-shaped spiral with respect to a lateral swaying axis (A) of the body, which is perpendicular to the main plane.

The invention relates to a wave power unit with a floating body (1), a submerged station (2) and flexible connection means (3) connecting the floating body (1) to the submerged station (100). The submerged station (100) has a stator 5 (5) and a moving part (6). According to the invention the flexible connection means (3) is provided with a damper (12). The damper (12) is arranged to absorb tensile forces in the flexible connection means (3). The invention also relates to a use of such a wave power unit and to a 10 method for producing and supplying electric energy.

The invention relates to a method for controlling a sluice drive (200) for a sluice (100), in particular for a roller-type sluice, preferably in a water power plant (1000), wherein the drive has an electrical machine, in particular an asynchronous machine (210), in particular an asynchronous motor/generator. According to the invention, provision is made for the electrical machine, in particular asynchronous machine (210), to have a fan brake (230), wherein the method comprises the steps of: releasing the fan brake (230) if an insufficient power supply is indicated, automatically operating the electrical machine, in particular asynchronous machine (210), wherein the electrical machine, in particular asynchronous machine, is operated as a generator in island mode in which a rotating field is automatically generated.
