Definitions

  • the present invention is generally related to renewable energy systems. More particularly, the present invention is related to wind power generator systems adapted for fixed and mobile electrical power generation systems and applications.
  • Wind is a force of nature that is all around us. It is harnessed to sail ships, pump water, and create electricity, just to name a few. Recent events in the world have highlighted the need for alternative methods of power production, whether it is from the wind, the sun, water, or organic matter. Changes in battery storage capacity and life and generator efficiency have made it so that individuals desiring to supplement their energy requirements may do so at a much more affordable cost over 15 years ago.
  • electric power generation systems can be classified into hydroelectric power generation, thermal power generation, nuclear power generation, solar power generation, biofuel power generation and wind power generation using wind energy.
  • Wind energy is limitless, purely domestic renewable energy that is freely available in the world.
  • the wind power generation system faces some difficulty in its stability due to fluctuation in direction and speed of air. Wind energy has been used as a source of power for sailing ships for several thousands of years, and until recently, we have been using it in water pumping and operating flour mills.
  • Recently, many new ideas and theories for windmill and wind power generation have surfaced, like propeller shaped blades as part of large, scaled power generators that rotate based on aerodynamics of the blade designs.
  • Wind generated power has been used as a source of electricity that can be used directly by buildings and other fixed infrastructure, or has been fed directly into public utility system grids for distribution and use by public utility customers. Wind generated electrical power will continue to find uses as its need increases at all levels and types of consumption and as an alternative energy to fossil fuels.
  • propeller of a wind power generator should ideally be positioned in the path of the flowing air. In most systems currently being deployed internationally, propellers and generators can reach height greater than 100 feet and rotational diameters greater than 50 ft.. Propellers currently used with wind power generators are designed in such a way to produce power output as various wind speed conditions press against propeller blades.
  • a system generating electrical power from wind includes a cowling located at a first end of a tubular housing to capture wind and directs it into the tubular housing.
  • At least one fixed helical vane can be integrated into the inner surfaces of the tubular housing in a spiral, adapted to further direct the captured wind into a spiraled air flow and focus the wind directly onto fan blades connected to an electrical generator located near a second end of the tubular housing where air is exhausted from the tubular housing.
  • a conical flange can be formed at the second end of the unit, said conical flange adapted to protect the can blades and also enables air to escape from the unit without interruption from exterior wind source moving along the sides of the unit.
  • a cone can be mounted at the front of the generator or fan blades facing air passing through the tubular housing. As air passes over the generator cone it can experience compression between the generator cone and housing resulting in increased pressure and velocity of the air, thereby increasing rotational speed of the generator blades and generator as the compressed air passes through the blades and exits the system's exhaust.
  • the system can be rotatably mounted on top of a pole for fixed residential or commercial applications. Mounting of the unit to poles, rooftops, beams and other fixed hardware can be facilitated with bearing and mounts that can withstand extreme fluctuations and high stress.
  • electrical contact discs plates
  • the generator and external modules e.g., batteries, converters, etc.
  • Sealed electrical contact dies can be integrated with the bearing and mounting mechanism adapted to rotatably mount the housing to a pole.
  • a fin can be provided in fixed attachment to a second end of the power generating system near the second end of the tubular housing to direct the front of the tubular housing into approaching wind by rotating the housing on a pole, thereby enabling the system to receive the maximum amount of available wind into the system.
  • the system can be integrated near the front of a moving vehicle to capture air as the vehicle moves forward, thereby generating electrical power from air for a load, such as hybrid vehicle batteries.
  • generated electrical power can be routed via electrical connections from the generator for direct storage in and then for later use from storage batteries.
  • power conditioning can be provided to generated power if necessary using conditioning circuits known in the art (e.g., filtering circuits).
  • conditioning circuits known in the art (e.g., filtering circuits).
  • the size of the present system is scalable to meet delivery requirements.
  • the housing can be made of a tough light weight metal or a composite that will be able to withstand harsh environments while meeting the highest of standards.
  • a cone can be located at the front of the generator/fan with its point facing facing incoming air/wind to cause the wind/air to flow directly onto fan blades and not encounter a flat surface typically associated with the back of a generator or center portion of a fan wherefrom blades extend. Pressure caused between the inner surface of the housing tubing and the cone/generator can force air directly onto the generator fan blades and outward past the fan blades where the air can be exhausted from the second end of the housing.
  • a cupped fan blade can be included to enhance the effect of air pressure on the fan blades and ultimately as rotation of the generator.
  • a clutching mechanism and/or mechanical breakaway can be provided to accommodate conditions where the wind speed exceeds rotational capabilities of the generator and/or power output requirements/thresholds.
  • Clutching can be provided in the form of a fan blade assembly designed with materials that can flex above threshold rotational speeds (RPMs) in order to prevent operation of the generator above damage causing thresholds, design parameters and generator capacity limits.
  • RPMs threshold rotational speeds
  • an electronic starting circuit can be provided in order to facilitate initial starting of the generator from periods when the generator is idle (e.g., no rotation due to lack of wind).
  • the electronic starting system can provide an initial release of electrical energy to the windings in the generator to thereby reduce the amount of wind required to spin-up or start rotation of the generator.

  • a generator cone 150 can be provided in front of the electrical generator 140, if the generator can be placed before the fan 130, or before the flat center portion of the fan (not shown), which supports fan blades extending there from, if the fan can be placed before the generator.
  • the electrical generator 140 and any electrical wiring associated therewith can be protected within the tubular housing 110 when the generator can be placed before the fan.
  • the electrical power from the electrical generator 140 can be routed via electrical connection 160 for immediate use by a load 180 (e.g., storage and later use in/from batteries) or can pass through a controller 170.

  • the system depicted in FIG. 2 is typical of what can be sued for fixed deployment, e.g., for use with residential and commercial applications.
  • FIG. 3 illustrates a view of the first end 300 of the wind driven electrical power generating system as shown in FIG. 1 , looking into the cowling 105 through the inside of the tubular housing 110 past helical vanes 120 towards the fan 130, in accordance with features of the present invention.

  • Fixed helices within a tube 110 as depicted in FIG. 1 increase the air flow as well as creating a spiral laminar air flow, avoiding turbulent air flow, thus spinning specifically designed vanes of a fan blade assembly 130 at an accelerated speed, thereby increasing rotational speed of the generator 140 for optimal power output with minimal velocity or wind speed conditions external to the system.
  • Fixed helical vanes 120 should be designed to achieve the direction of incoming air into a spiraled air flow.
  • the helical vanes 120 can conform to a concave inner surface of the tubular housing 110 enclosure inner surface while insuring the optimal three-dimensional helix angles.
  • the vanes 120 can direct and increase the spiral rotation and velocity of the air, thus more efficiently spinning the fan blade 130 thereby increasing rotational efficiency of the generator for optimal power output.

  • a conical flange 210 formed at the rear of the unit 200 protects the blades and also enables air to escape from the unit without interruption from exterior wind source moving along the sides of the unit.
  • the conical flange 210 also assists in unit orientation along with the fin 220.
  • the fin should be balanced so that half its weight is on either side of its axis, but also designed so that the momentum about the axis of the areas exposed to the wind are unequal. This unequal moment causes the fin to rotate to minimize the force of the wind on its surface.
  • the design of the fin 220 causes the end with the smallest moment to turn into the wind, pointing to the source of the wind.
  • the directional fin can be balanced so that half its weight is on either side of its axis, but also designed so that the momentum about the axis of the areas exposed to the wind are unequal. This unequal moment causes the fin to rotate to minimize the force of the wind on its surface.
  • the design of the fin in this manner can cause the end with the smallest moment to turn into the wind, thereby enabling the unit to more effectively capture the wind.
  • FIG. 6 illustrates a fan blade assembly 600 with cupped fan blades 610, in accordance with features of the present invention.
  • the fan blade assembly 600 can be designed with a cupped fan blade design such that each blade can enhance each blade's ability to capture and be moved by wind passing through and managed by the housing and its helical vanes. It is possible to manufacture the fan blade assembly with materials that will flex above threshold rotational speeds (RPMs) in order to prevent operation of the generator above damage causing thresholds, design parameters and generator capacity limits. But it should also be appreciated that a clutching mechanism or mechanical breakaway can be provided between the fan blade assembly and the electrical generator to accommodate conditions where the wind speed exceeds rotational capabilities of the generator and/or power output requirements/thresholds.
  • RPMs threshold rotational speeds
  • FIG. 7 illustrates a turbulent flow 710 of a wind inside passage tube of wind driven electrical power generating system, which can be implemented in accordance with a preferred embodiment.
  • Air flow occurs only when there is a difference between pressures. Air will flow from a region of high pressure to one of low pressure. Bigger the presser difference, faster the flow. Thus air flows in during inspiration because the alveolar pressure is less than the pressure at the mouth; air flows out during expiration because alveolar pressure exceeds the pressure at the mouth such that to double the flow rate one must quadruple the driving pressure.
  • air flows at higher velocities, especially through an airway with irregular walls flow is generally disorganized, even chaotic, and tends to form eddies.
  • turbulent flow This is called turbulent flow, and is found mainly in the largest airways, like the trachea.
  • a relatively large driving pressure is required to sustain turbulent flow.
  • Driving pressure during turbulent flow is in fact proportional to the square of the flow rate such that to double the flow rate one must quadruple the driving pressure.
  • FIG. 7 also illustrates a laminar flow 720 of a wind inside passage tube of wind driven electrical power generating system, which can be implemented in accordance with a preferred embodiment.
  • laminar flow When flow is low velocity and through narrow tubes, it tends to be more orderly and streamlined and to flow in a straight line. This type of flow is called laminar flow. Unlike turbulent flow, laminar flow is directly proportional to the driving pressure, such that to double the flow rate, one needs only double the driving pressure.

Abstract

L'invention concerne un système de génération de courant électrique à partir du vent, comprenant un capotage pour capturer le vent et le diriger dans un boîtier tubulaire. Au moins une aube hélicoïdale fixe peut être intégrée dans les surfaces internes du boîtier tubulaire en une spirale, adaptée pour diriger en outre le vent capturé en un écoulement d'air en spirale, et pour concentrer le vent directement sur des pales de ventilateur de générateur électrique situées à proximité d'un échappement du système. Un cône de générateur peut être monté à l'avant du générateur ou des pales de ventilateur, pour diriger l'air passant à travers le boîtier tubulaire. A mesure que l'air passe au-dessus du col du générateur, il peut rencontrer une compression entre le cône de générateur et le boîtier, ce qui a pour résultat une pression et une vitesse accrues de l'air, augmentant ainsi la vitesse de rotation des pales de générateur et du générateur à mesure que l'air comprimé passe à travers les pales et sort de l'échappement du système. Le système peut être utilisé pour des applications fixes ou mobiles.
