WINDMILL ELECTRIC GENERATING PLANT Russian patent published in 2000 - IPC

FIELD: electrical engineering; wind-power engineering. SUBSTANCE: plant has tower- mounted composite rotor incorporating Savonius windwheel installed on central shaft and at least two airfoil blades hinged to upper and lower crosspieces coupled with central shaft, rigid joints between lower crosspieces and central shaft, rotor speed limiter, central-shaft mounted generator unit with generator kinematically linked with step-up gear, free-wheel expanding clutch, and central shaft that carries brake member; novelty is that upper end of central shaft is mounted at windwheel upper end level, upper crosspieces are attached to central shaft through hinged joints, and that crosspieces are set at acute angles to plane perpendicular to central shaft with distance between them increasing towards blades; novelty is also that rotor speed limiter has at least one centrifugal speed governor board built integral with airfoil blades and mounted on shaft fixed at bottom part of blade. EFFECT: improved operating reliability of plant. 5 cl, 9 dwg
