Definitions
- the present invention relates to a new instrument for the generation of electrical energy.
- the object of the invention is a generation device comprised within the renewable energy industry by transforming wind energy into usable electrical potential.
- three known physical principles are integrated: the structural coupling to the natural frequency of oscillation, the generation of vortices in fluids and the electromechanical coupling that some materials present thanks, for example, to the ferroelectric effect or the piezoelectric effect.
- the present invention describes a device that is based on three physical principles or fundamentals. These, separately, have a wide application in the industry:
- the first physical basis is the electromechanical coupling.
- actuators positioners, motors
- loudspeakers introducing electrical energy and obtaining mechanical energy
- pressure, position, contact, deformation and transducer sensors various types (to which mechanical energy is introduced obtaining electrical energy).
- the resonant vortex wind turbine presented here is a solution to the problems presented by conventional multi-blade wind turbines that have been described previously.
- the wind turbine resonant by vorticity consists of a vertical, semi-rigid and grounded device on the ground surface.
- the most visible part is a vertical block or mast that, having no moving parts (gearboxes, gears, shafts, rotors, etc.), does not require lubrication or exchange of parts due to wear or fatigue. It is manufactured partially or entirely by materials with high electromechanical coupling.
- F v is the frequency of occurrence of vortices
- V is the velocity of the air
- h the characteristic length of the geometry of the obstacle (for example, the diameter in case of speaking of a circular section)
- S the dimensionless number of Strouhal of the fluid.
- the device object of the invention has several spatial modes of oscillation.
- the so-called first mode of oscillation is one in which one end remains static and the opposite end, the highest, suffers a maximum travel.
- the value of its frequency is given by:
- f n is the natural oscillation frequency for its nth harmonic, / is the moment of sectional inertia, E the Young's modulus of the material, di is the density of the bar per unit length, K n is the n - This swing mode of the bar is already a damping constant.
- the frequency of oscillation of a body depends on its density, its moment of sectional inertia and its elastic stiffness constant or Young's modulus. Since the frequency of occurrence of the vortices depends on the air velocity (which is not controlled and is variable in time), to tune or equalize both frequencies (natural oscillation and vortex generation) any of the parameters can be modified of control on which the natural oscillation frequency of the mast depends, preferably on all others, Young's modulus. This can be achieved by externally modulating the voltage to which the electromechanical coupling materials that conform it are subjected.
- the vortexing wind turbine has an electronic equipment dedicated to managing a control loop where output is the voltage value to which the materials with electromechanical coupling are subjected and the input is the wind speed. Its value can be obtained with a standard anemometer or better, using the stationary torsion of the wind turbine mast generated by the drag force. Another of its tasks is to filter and condition the energy generated by the device before being supplied to the following stages of investment and filtering that allow it to be introduced into the electricity grid.
- the most natural location of the electronic control and regulation equipment will be the one that does not interfere with the natural flow of air.
- the ground anchor is made with a solid foundation or basement of typical binding material such as concrete, cement, plaster, mortar or mortar. It is of high weight and should provide a firm and stable grip on the ground.
- z is the height at which the air velocity is to be known
- h is the height at which the air velocity is known
- V z and V h are respectively the unknown and known air velocities. Since the frequency of vortex generation depends on the velocity of the air, we must introduce the Hellmann exponential law and Karman's formula in its geometry, increasing its diameter based on the expected air velocity or what is the same, adjusting its diameter with the height.
- This new wind turbine system can be used in areas that can be exploited by conventional systems and, due to its characteristics, can be used in environments (urban and industrial) generally forbidden from traditional wind turbines.
- Figure 1. Shows a schematic representation of a section of the elevation corresponding to the wind turbine resonant by vorticity.
- Figure 2. It shows a graph that represents, by way of example, the variation of the thickness of the mast against its height (based on the exponential law of Hellmann and Karman's formula). Being in this case its circular section is given the measure of the radius R in meters versus the height H also in meters.
- the wind turbine resonant by vorticity does not have gears, bearings, etc., so its assembly consists of placing the physically solidary components in the position described and in physical or electrical contact between them.
- a hole is made on the ground (12) of sufficient dimensions to accommodate the basement (1) made of cement or concrete like any foundation of a building or structure.
- the mast (4) is fixed to the basement (1) attached to it by its lower part in an anchor zone (5) allowing the highest part of the mast (4) to oscillate freely with no other impediment than the elasticity itself of the material.
- the mast (4) made up of elements with high electromechanical coupling (13), is connected to the electronic control and regulation equipment (3) located in the watertight hole (2) with which it has for this purpose the basement (1). Said connection is made by electrical conductors (7) introduced by a passage or conduit (6) also made in the basement (1).
- the connection to the power grid of the installation (8) is carried out with connecting cables (9) that will be channeled through a ditch made in the ground (12) and that are extracted from the basement (1) by means of watertight passage elements or cable glands (10).
- the access to the watertight hole (2) is carried out by a cover (11) that allows access to its interior and to carry out assembly and maintenance interventions.
- the mast (4) is of circular section (15) so as not to depend on the direction of origin of the wind and of variable radius R as a function of the height H
- a desired natural oscillation frequency for example, 8 hertz (determined among other things by Young's modulus of the material that forms it) is passed from a section (15) of 82.9 mm. radius 1 meter high from the ground (12) up to 105.3 mm at 4 meters.
- the wind of a laminar and stationary character (14) strikes the mast (4), producing an unusable drag force (18) and a lift force (19) whose meaning and magnitude vary over time.
- the lifting forces (19) are the product of these vortices (16).
- the control and regulation equipment (3) actively modulates Young's modulus or mast elasticity modulus (4) by varying the electrical stresses to which the elements are subjected with high electromechanical coupling (13) that compose it, thus tuning its natural oscillation frequency with the frequency of vortexes (16).
- the electrical network of the installation (8) collects the energy provided by one or several wind turbines resonant by vorticity and can be equipotential (direct current). It is responsible for sending all the energy to an electrical substation that transforms and conditions it according to the requirements of the electricity company or center that receives said electrical power.
- the vortexing resonant wind turbines can be mimicked with a color consistent with the surrounding terrain, although, in the preferred embodiment, the use of refractory paints (white, silver, etc.) is recommended to reduce the degradation caused by solar radiation.
