  • Wind power generator
    Patent number: 7161259
    Abstract: A windmill driven electric generator is described with an air sealed closed chamber surrounding rotating and stationary parts to prevent condensation problems during times when the windmill is standing still due to a lack of wind. The closed chamber may be provided with a super atmospheric pressure to avoid entry of moisture-laden air. An air drier is used to maintain the closed chamber air dry and at a temperature that is below the dew point. Various embodiments are described.

  • DC local grid for wind farm
    Patent number: 6420796
    Abstract: A wind farm is described in which two or more windmills are provided with each having a generator to generate electrical power. The energy supplied by the generators is output to a general a.c. grid which is set at a standard voltage. The electrical power supplied by the windmills is injected into the a.c. grid via a d.c. interconnecting grid to which a plurality of windmills are linked and with a converter. The d.c. voltage in the d.c. interconnecting grid is set as a function of the electrical power to be generated by a generator.

  • Artificial wind turbine island
    Patent number: 6294844
    Abstract: The invention relates to an installation comprising windmills (1) which are mounted in a frame (5, 6, 7) said frame is provided with float bodies (15), and it is capable of rotation about a vertical axis in order to turn the windmills towards the wind. In order to keep the windmills upright, supporting means, for example a body (16) which is anchored to the bottom, are disposed some distance away from the plane of the windmills. Furthermore, means are provided for improving or simplifying maintenance.
