WINDMILL ELECTRIC GENERATING PLANT Russian patent published in 2007 - IPC F03D3/00 

FIELD: wind-power engineering; electric power generation.

SUBSTANCE: proposed windmill-electric generating plant characterized in enhanced capacity at same size and in full utilization of wind energy at any wind speed has vertical shaft revolving in bearings mounted in frame structure, blades, and wind guide; vertical shaft mounts rigidly fixed cross-like frame that carries drive blades with limiters and vertically disposed driven blades forming in working travel single working surface whose width equals windmill radius, as well as intercoupled synchronizers; top and bottom wind-guides are installed below and above blade level and have vertical ribs disposed at acute angle to windmill radius, they are divided into sectors swinging on axle mounted perpendicular to windmill radius and offset from sector center toward windmill center in ratio of 2 : 1 of sector length; short internal side of bottom wind-guide sector is heavier than external one for which purpose it is provided with counterpoise.

EFFECT: enhanced efficiency, reliability, service life, and safety of plant, reduced cost of power generation and plant manufacture, reduced payback time.
