  • the shape and configuration of the rotor typically identify the behavior of a specific wind turbine in a particular environment.
  • every turbine has a limitation of working on a specific wind speed or in between a prescribed range of wind speed. If the speed of wind is too low then the turbine fails to operate. Only the high velocity of the wind is partly utilized and potential portion of velocity is untapped. Hence most of the turbines generate electricity for a limited time, only when preferred wind speed is available. Further the dependency of the preferred wind speed restricted the use of wind turbines in specific geographical regions.

  • the air in the air reservoir 15 pushes the diaphragm 17 thereby raising the level of liquid in the liquid reservoir 23.

  • This arrangement has the advantage of maintaining a constant pressure in the air outlet pipe 25, even when the rotor 1 is not able to rotate at a desired speed or not rotating at all, since the potential generated in the liquid reservoir compensates for any drop in the pressure in the air reservoir. Similarly when the rotor 1 is rotated at high velocity then the addition pressure generated is absorbed by the liquid reservoir that may be utilized when the rotor is not rotating at required velocity. Hence the turbine gets air at a constant velocity, irrespective of variation in rotor rotating speed.
  • Figure 3 illustrates pneumatic arrangement for the windmill according to another embodiment of the present invention.
  • the air reservoir is configured vertically and is connected through a 'U' tube pipe.
  • Such an arrangement may further evade the use of diaphragm in the air reservoir.
  • the 'U' tube pipe may have a valve and a knob for selectively stopping ' the flow of water between the water reservoir and the air reservoir.
  • the arrangement disclosed in the present invention utilizes the entire velocity of wind to generate electricity without fluctuation by converting and storing the excess velocity

Abstract

La présente invention concerne une éolienne comprenant un rotor, une pompe à air, un réservoir d'air, un réservoir de liquide, une conduite d'évacuation, une turbine et un générateur. Le rotor est conçu pour convertir de l'énergie éolienne en mouvement rotatif. La pompe à air est raccordée au rotor et est conçue pour fonctionner avec la rotation du rotor. Le réservoir d'air est raccordé à la pompe à air par le biais d'un clapet anti-retour. Le réservoir de liquide est maintenu à une hauteur particulière et est raccordé au réservoir d'air. Le réservoir de liquide est conçu pour gagner du potentiel avec l'augmentation du volume de l'air dans le réservoir d'air. La conduite d'évacuation est disposée dans le réservoir d'air et est conçue pour permettre l'évacuation sélective de l'air depuis le réservoir d'air. La turbine est raccordée à la conduite d'évacuation et est conçue pour tourner lors de l'évacuation de l'air depuis la conduite d'évacuation. Le générateur est relié à la turbine pour la génération d'électricité lors de la rotation de la turbine.
