Apparatus for converting sea wave energy into electrical energy
TLDR
In this article, the authors describe an apparatus for converting sea wave energy into electrical energy, comprising a buoy which executes periodic forced vibrations, with a natural frequency approximating the wave frequency, along the vertical axis of the buoy in a manner that the buoy moves with respect to the wave surface.Abstract:
An apparatus for converting sea wave energy into electrical energy, comprising a buoy which executes periodic forced vibrations, with a natural frequency approximating the wave frequency, along the vertical axis of the buoy in a manner that the buoy moves with respect to the wave surface, and a turbogenerator for converting the air flow stream kinetic energy into electrical energy. The buoy is provided with an air chamber and a hydraulic piston, the air chamber communicating through an air duct with the turbogenerator. The latter includes a generator, a turbine stage with a stator and a rotor mounted on the same shaft with the generator. The turbogenerator turbine stage is provided with a supplementary stator disposed downstream of the turbine rotor and made symmetrical with the turbine stage stator with respect to the plane of rotation of the rotor.read more
