Definitions
- the present invention relates to a new design of Self-firing Wind Turbine, with which it is intended to simplify the execution of this type of machines by providing them with more degrees of freedom by having self-tuning structures and self-stable rotors, in which the wind force itself it is used to protect them instead of destroying them, since they work in favor of the current, making better use of this force and guaranteeing that in no case, structure, footing and ground withstand forces greater than the nominal ones.
- the property that the structure can tilt to lower the head and rotor at a low height above the ground reduces assembly and maintenance times and costs, as well as the necessary infrastructure, resulting in a highly competitive and profitable product applied to the manufacture of wind turbines connected to the network and / or in those cases in which it is intended to take advantage of wind energy for pumping, energy saving, in isolated areas of the network.
- the current systems are:
- SUBSTITUTE SHEET (RULE 26) Three-pole wind turbines with aerodynamic loss regulation with fixed speed asynchronous generator.
- the type of wind turbine is tripala with tubular tower to leeward, regulation by loss and / or change of step and active guidance system.
- the rotor drives a multiplier and this to the generator;
- a disc brake is placed on the output shaft of the multiplier.
- the gutter whose bushing is rigidly fixed to the shaft that is embedded in two bearings moored solidly to the gondola chassis, or is mounted directly on the input shaft of the multiplier.
- They are slow rotors, with blade tip speeds of about 55 m / s, separated their plane of rotation about five meters from the axis of the
- the rotor In most cases the rotor is located windward from the tower (frontal wind). This has the advantage of reducing the fatigue loads on the blades by minimizing the shadow effect of the tower and avoiding the aerodynamic noise produced by the blades when the rotor is in the lee.
- three-sided machines represent 80% of the wind turbines installed. However, as the diameter of the rotor increases, the number of two-bladed wind turbines increases, these being usually leeward design, in which the shadow effect of the tower on the blade is more pronounced, producing significant fatigue and vibration.
- SUBSTITUTE SHEET (RULE 26) structures Power control: The power generated is regulated by two methods, aerodynamic loss control or step change control. The latter allows an optimal generation over a wide range of wind speeds, allowing, in addition, a safety system against high winds (flag blades), while. additional braking devices are necessary with the first system. Those of the change of step carry complex moving parts with the consequent risk of failures and greater maintenance needs.
- SUBSTITUTE SHEET (RULE 26) unwind them.
- the specific energy (kWh / m 2 ) increases with the diameter of the rotor due to the higher tower height, which in most cases leads to an increase in wind speed.
- this increase in speed may not compensate for the increase in manufacturing costs when, while maintaining the current technical concepts of design, attempts are made to design machines with diameters greater than 50 meters of rotor.
- said self-stimulating structure formed by two parallel armed beams positioned as a "trellis"
- the structure in the form of "Boomerang" allows us, on the one hand, to distance it from the plane of rotation of the blades, while still maintaining the dihedral shape, and on the other, to locate the center of gravity of the
- SUBSTITUTE SHEET (RULE 26) rotor in the vertical axis of the column, eliminating the gyroscopic effects (precession) that tend to dislodge the rotor.
- the blades are two instead of three, of smaller unit weight, being constructed by an aluminum core trunk elliptic of density 2.65 Kg / dm 3 , on which the aluminum ribs are dragged aerodynamically, covered by a 1.2 mm sheet of polycarbonate with a density of 1.2 kg / dm 3 riveted on the ribs, aerodynamically shaping the blade. Its center of gravity is 39% of its length from the mooring flange.
- SUBSTITUTE SHEET (RULE 26) of the centrifugal action, they result in a dominant tensile stress, supported by the entire elliptical section that forms the blade's core, allowing rapid rotors to be designed with tangential speeds of the order of 75 m / s instead of 55 m / s of the traditional shovels, which reduces the input pairs in the multiplier, yes as its degree of multiplication, resulting multipliers that for our application weigh 2.2 Tm, instead of 7.6 Tm for machines of 1 MW of power, with rotor diameters from 60 m to 11 m / s wind speed.
- the blades that form the dihedral have an angle of 12 ° to 14 ° with the vertical, leaving the center of application of the axial thrust, 70% of the bisector of the dihedral, far behind its center of gravity, which makes it self-stable.
- the use of four-pole generators (1,500 rpm) and medium voltage, 6 KV, reduces their weight and eliminates the transformers at the foot of the machine, while reducing the number and section of the electric power transmitting cables .
- the generator is located on the axis of the column ( Figure 5 Mark 9) (fixed to its upper end instead of being located on the head) to avoid the use of rotating power transmission fittings, the
- SUBSTITUTE SHEET (RULE 26) Power captured by the rotor is transmitted by an oleohydraulic circuit (Figure 5 Mark 15), whose central and pumps will be located in the rotor head, further reducing the specific weight of the same by having high pressure hydraulic pumps (350Kg / c 2 ), a power to weight ratio of the order of 0.4 kg / Kw instead of 5.5 kg / Kw of electric generators.
- Rotary fittings on high power machines are expensive and complicated components
- Figure 1 It serves as a clarification to claims 1,7 and 8. It shows the wind turbine and leeward wind turbine drawings, profile views. The scale corresponds to machines of 1MW at 11 m / s. The different brands of this figure indicate:
- Figure 2 It serves as a clarification to claims 2 and 3. It shows the tilting of the head and rotor assembly due to the axial thrust, as opposed to the hydraulic cylinders, for the windward version.
- SUBSTITUTE SHEET (RULE 26) parallel armed beams positioned on edge, on which it tilts.
- the different brands of this figure indicate:
- SUBSTITUTE SHEET (RULE 26) bearing located at the top end of the column on which it pivots.
- the servomotor that drives the generator through the hydrostatic transmission located from the hydraulic power plant located in the rotor head at the upper end of the self-tuning structure, is placed on the mobile ring.
- the different brands of this figure indicate:
