Description
(I) technical field
The invention belongs to the technical field of green energy wind power generation, and particularly relates to innovation on the aspect of wind power utilization of a traditional wind generating set, which changes the current situation that the wind energy of the traditional wind generating set is horizontally acquired and directly utilized.
(II) background of the invention
Wind energy is an inexhaustible and continuously regenerated green energy, and the existing wind generating set drives a fan-shaped paddle impeller of the wind generating set to rotate by utilizing the kinetic energy of wind and then promotes the rotating speed by multi-stage speed increasing to promote the wind generating set to generate electricity.
(1) Although wind energy is a continuous renewable energy source, the wind speed is large and small, so that the existing wind generating set has unstable working efficiency and uncertain working state when utilizing the wind energy, and the phenomena of confusion of low wind energy utilization rate and unstable power generation to generate 'garbage electricity' are caused.
(2) Different wind speeds have different influences on the working efficiency (generating capacity) and the working state (stability and fault generation) of the existing wind generating set. The problem that the generated energy is insufficient due to the fact that the working efficiency of an existing wind generating set is too low can be caused by insufficient wind speed; if the wind speed is too high, the working stability of the traditional wind generating set is reduced, the wind generating set in work frequently breaks down, and the phenomenon of insufficient generating capacity is also caused.
(3) The existing wind generating set has the disadvantages of high input cost, high installation difficulty and inconvenient maintenance. The impeller and the generating equipment of the existing wind generating set are arranged on a cylindrical high-altitude tower cylinder, and the existing wind generating set is large in size, heavy in weight, high in installation standard and requirement, large in installation difficulty and inconvenient to maintain; in order to maintain the safety of the cylindrical high-altitude tower and the wind generating set equipment mounted on the cylindrical high-altitude tower, the construction investment cost is overlarge due to the requirements on the design and construction of a foundation and a foundation, the structural material selection of the cylindrical high-altitude tower, the mounting construction and the like.
(4) Considering the installed capacity of the wind power plant, the length of an impeller of the existing wind generating set is mostly more than 100 meters, and if the wind power generating device is located and built on a conventional bird migration path, the blade can damage birds.
(5) The wind power station of the existing wind generating set has high noise, generates infrasonic waves with a certain magnitude and has high noise influence on residents close to the wind power station.
(6) Therefore, the technology, particularly the structure, of the existing wind generating set is still to be improved and improved, and the technical point is the standing point and the starting point of the invention.
Disclosure of the invention
In view of the defects of the existing fan-paddle impeller blade type wind generating set that the wind speed cannot be effectively adjusted, the construction cost investment is too large, the installation and maintenance are inconvenient, and the like, the invention aims to provide a wind power generator system which can comprehensively and horizontally acquire the wind power, longitudinally accelerate the wind speed, effectively adjust the wind quantity of an air inlet, store energy in a multi-mode manner at high wind speed, instantaneously release the stored energy at low wind speed (millisecond level) for supplement, ensure the high-position operation of the wind power generator system and generate power at high quality, so as to solve the defects of the existing fan-paddle impeller blade type wind generating set and achieve the following aims:
(1) when the wind power generation system is in a high wind speed (within a normal wind speed range), under the condition of ensuring high-position operation and high-quality power generation of the wind power generation system, energy is stored for redundant energy in a vacuum electromagnetic gear transmission flywheel energy storage system (frequency modulation) and a vacuum electromagnetic gear transmission compressed air energy storage system (peak modulation) mode, and the utilization rate of wind energy is improved to the maximum extent;
(2) during the time of the super high wind speed (extremely bad weather, surpass normal high wind speed scope like typhoon, when generating set whole operating condition and safety influence), the intelligent rail formula arc mechanism that keeps out the wind is carried in the preferential start, reduces the side direction pressure of strong wind-force to the mechanism through letting out the wind mode, secondly collects accelerating device's elevating system through omnidirectional wind energy, intelligent control descends and carries out the effective regulation of air intake amount of wind, gather accelerating device and descend to collecting the cabin completely until omnidirectional wind energy.
(3) When the wind speed is low, the technology of instantly releasing stored energy by a magnetic transmission vacuum flywheel energy storage system (frequency modulation) (millisecond level) and supplementing wind power by releasing compressed air by an air compression energy storage system (peak regulation) is adopted, so that the high-position operation and high-quality power generation of a wind driven generator system are ensured; the wind power capability of the generator set above the normal power generation standard is ensured to be achieved at the lowest (the problem that the existing wind power generation is unstable and is commonly called as 'garbage power') is avoided.
(4) The invention changes the mode that the existing wind generating set directly drives the fan-shaped impeller of the wind generating set to rotate by utilizing the kinetic energy of wind and then promotes the rotating speed by the multistage speed increaser to promote the wind generating set to generate electricity, but the invention horizontally collects the longitudinal speed by wind energy in all directions and drives the generating set rotating by the rotating shaft of the high-speed turbine fan blade to generate electricity. The generator can be installed in an upper or lower mode or in a combination mode. The invention does not need the long impeller and the hub, the air guide sleeve and the pitch system, the yaw speed reducer, the high-speed brake disc and other device mechanisms which are necessary to be matched with the existing wind power generator, simultaneously, the wind power collection mode is changed, the utilization efficiency of the wind power is effectively improved by longitudinally increasing the speed of the wind power, the height of the high-altitude tower cylinder can be relatively reduced, the design of the supporting system and the foundation and the construction standard are correspondingly reduced, the construction land can be correspondingly reduced, and the construction investment under the condition of the same power generation capacity (installed capacity) is greatly reduced.

Specifically, the present invention (fig. 20) is designed to have the following dimensions:
RHV＝π(R 1 /2) 2 V 1 (formula 1)
RHV＝π(R 2 /2) 2 V 2 (formula 2)
Obtained by the formula 1: v 1 /V＝RH/π(R 1 /2) 2
Obtained by the formula 2: v 2 /V＝(1+0.407)×(RH/π(R 2 /2) 2 )
R-width of the omnidirectional horizontal collection surface of the wind energy (the diameter of the structure body of the omnidirectional horizontal collection longitudinal speed-raising device of the wind energy); h- - -wind energy omnidirectional collection surface height; v-wind energy omnidirectional horizontal acquisition of surface wind inlet speed; r 1 -first turbine inlet diameter; v 1 -first turbine inlet air velocity; r 2 -secondary turbine inlet diameter; v 2 The wind inlet speed of the secondary turbine (in theoretical calculation, assuming that the wind utilization coefficient of the primary turbine reaches 59.3% at the maximum, the wind blowing to the secondary turbine through the primary turbine is 40.7% of that at the primary turbine).

(5) When an object retards the wind so that the speed of the object is reduced, the kinetic energy in the wind is partially converted into pressure energy on the object. The wind power passes through the turbine blades to rotate the turbine rotating shaft, and the rotating speed of the turbine rotating shaft is in direct proportion to the flow of the wind power; the pressure of wind power on the blades generated by the turbine blades is in direct proportion to the square of the rotating speed of a rotating shaft of the turbine; the power of the fan is proportional to the cube of the rotational speed of the turbine shaft.
Under an ideal airflow model state, the power absorbed from the wind after the wind passes through the impeller (turbine blades) of the wind turbine is as follows:
P＝pC P A D V 3 /2
p- -the power (W) the turbine absorbs from the wind; p- -air Density (kg/m) 3 )；C P -a wind energy utilization factor; a. the D -area swept by fan blade (m) 2 ) (ii) a V- -speed of wind energy as it passes over the blades (m/s); l- -impeller length (m).
Namely: p Impeller ＝pC P A D V 3 /2＝pC P A D V 3 /2＝pC P πL 2 V 3 /2
P First-stage turbine ＝pC P π(R 1 /2) 2 (15.92V) 3 /2
P Two-stage turbine ＝pC P π(R 2 /2) 2 ( 9.96V) 3 /2
If P Impeller ＝P First-stage turbine
Then: pC P πL 2 V 3 /2＝pC P π(R 1 /2) 2 (15.92V) 3 /2
L 2 V 3 ＝(R 1 /2) 2 ( 15.92V) 3
L/(R 1 /2)＝(15.92) 3/2 ≈63.52
L/R 1 ＝(15.92) 3/2 /2≈31.76
If P Impeller ＝P Two-stage turbine
Then: pC P πL 2 V 3 /2＝pC P π(R 2 /2) 2 ( 9.96V) 3 /2
L 2 V 3 ＝(R 2 /2) 2 (9.96V) 3
L/(R 2 /2)＝(9.96) 3/2 ≈31.43
L/R 2 ＝(9.96) 3/2 /2≈15.72
The ideal conclusion obtained according to the theoretical calculation is as follows: when the power of the wind generating set is comparable, theoretically taking the design size proportion of the invention as an example, when the radius of the first-stage turbine blade is 1 meter, the length of the traditional impeller is equivalent to 31.76 meters, and when the radius of the second-stage turbine blade is 1 meter, the length of the traditional impeller is equivalent to 15.72 meters.

When the vacuum electromagnetic gear transmission energy storage flywheel transmits energy to the wind driven generator permanent magnet gear transmission large flywheel and the high-level operation of the wind driven generator between 1.0 and 1.02 storage coefficients cannot be maintained (or the energy storage flywheel does not release energy), the compressed air deflation intelligent valve is opened, and after the released compressed air is heated by the heat storage and heat preservation water tank, 4 groups of symmetrical compressed air pipelines leading to the first-stage turbine release compressed air to the first-stage turbine so as to maintain the high-level power generation of the wind driven generator set at low wind speed.

The top surface of the 1 st small circle at the bottom is lower than the top surface of the 2 nd small circle at the middle to form a first-stage air outlet and install a first-stage turbine; the middle 2 nd small round top surface is lower than the topmost 3 rd small round top surface to form a second-stage air outlet and install a second-stage turbine; the first-stage turbine and the second-stage turbine share a rotating shaft, the first-stage turbine mainly improves the rotating speed of the rotating shaft of the turbine, and the second-stage turbine increases the torque of the rotating shaft of the turbine so as to ensure high-level operation of the wind generating set under high power load (the first-stage turbine and the rotating shaft are rigidly fixed, the second-stage large turbine transmits power to the rotating shaft through a forward gear, when the rotating speed of the rotating shaft is higher than that of the second-stage large turbine, the second-stage large turbine does not transmit power to the rotating shaft and is in an idle running state, and when the rotating speed of the rotating shaft is lower than that of the second-stage large turbine, the second-stage large turbine and the first-stage turbine transmit power to the rotating shaft together so as to increase the rotating speed and the torque of the rotating shaft). The upper part of an inner small circle 1 is fixed with a turbine rotating shaft through a bearing, the turbine rotating shaft is connected with a wind generating set on a bottom plate, non-rotating parts such as a shell of the wind generating set are fixed below a horn-shaped arc structure through bolts, and rotating parts such as a rotor of the wind generating set, a first-stage turbine, a second-stage turbine, a rotating shaft and a permanent magnet gear transmission large flywheel on the upper part are fixed on the bottom plate through a track bearing, a supporting bearing and a positioning bearing; the bottom plate is also symmetrically provided with a vacuum electromagnetic gear transmission energy storage flywheel, a vacuum electromagnetic gear transmission air compressor, an electromagnetic gear transmission intelligent control power supply circuit, a vacuum electromagnetic gear transmission air compressor cooling heat exchange medium storage tank and pipeline, a compressed air charging and discharging intelligent valve assembly and the like.
(2) The device is installed according to an upper-mounted type mirror image combination and a lower-mounted type mirror image combination, 2 independent wind energy collecting surfaces and a first-stage turbine and a second-stage turbine (a first-stage air outlet and a second-stage air outlet) are arranged at the upper part and the lower part respectively, and the symmetrical force balance of the device structure is formed by the upper part and the lower part of the air outlets, so that the stability of the structure and a tower frame is improved; the upper-mounted type generator set and the lower-mounted type generator set are mutually independent to form a power generation system, the middle of the power generation system is connected with a heat storage and heat preservation water tank (heat preservation water in cold regions can be changed into antifreeze) through a compressed air charging and discharging balance annular pipeline (figure 13, figure 1 and figure 2), and the upper-mounted type generator set and the lower-mounted type generator set share one set of compressed air energy storage tank and the heat storage and heat preservation water tank.
(3) The invention has the advantages that when the wind energy resource is rich, the height of the tower can be adjusted to install a plurality of sets of generator sets on one tower structure, and the installed capacity of a single tower is increased; when wind energy resources are relatively deficient, the height of the tower frame is adjusted to increase the number of horn-shaped structures, and the wind energy collection area is increased; when the installed capacity is small, the upper-mounted type or the lower-mounted type can be adopted independently.
2. The intelligent balance and level-adjusting device for the intake air (comprising a lifting mechanism and a sinking cabin) comprises the following three conditions that the position of the rail-loaded intelligent wind shield is intelligently controlled by a wind direction and wind speed measuring instrument, and the rail-loaded intelligent wind shield is intelligently controlled according to actual conditions, namely, the following three conditions are shown in the drawing 5, the drawing 6, the drawing 7, the drawing 8, the drawing 9, the drawing 10, the drawing 11 and the drawing 12:
(1) under the condition of safe wind speed (figure 6), the wind energy horizontal acquisition device is ensured to be opposite to the incoming wind direction, and the wind shield is used for leading all the acquired wind power to pass through the primary turbine and the secondary turbine and then to be discharged from the wind outlet on the other side of the incoming wind direction;
(2) under the safe and controllable condition of high wind speed (shown in figures 7 and 8), the intelligent control rail-loaded intelligent wind deflector moves towards the incoming wind direction, and a certain distance is reserved between the two wind deflectors to release partial wind power. The collected wind power is partially discharged from the air outlet through the upper turbine and the lower turbine (the requirements of normal power generation of the wind generating set and energy storage of the energy storage mechanism are met), and partially discharged from the air outlet without passing through the turbines and the air outlet;
(3) under the condition that the ultrahigh wind speed is safe and uncontrollable (figure 10), the rail-carrying type wind shield is intelligently controlled to completely shield the incoming wind, all wind power slides through the arc surface of the arc wind shield, and the wind generating set does not work under the condition;
(4) the invention also considers that the lifting mechanism of the wind energy omnidirectional horizontal acquisition longitudinal speed-increasing device is installed, the sinking cabin of the wind energy omnidirectional horizontal acquisition longitudinal speed-increasing device is arranged (the device can also be used as a maintenance platform), and when the situation that the wind speed is safely uncontrollable due to ultrahigh wind speed occurs or maintenance is needed, the lifting mechanism of the wind energy omnidirectional horizontal acquisition longitudinal speed-increasing device is lowered into the sinking cabin through intelligent control.

The wind power generation device is characterized in that a 3-layer horn-shaped arc structure is adopted, a first-stage turbine, a second-stage turbine, a first air outlet and a second air outlet are formed on 3 layers of small circles on the upper part of the second-stage turbine, a 1 st small circle is lower than a 2 nd small circle and is used for installing a special bearing to fix a turbine shaft and a first-stage turbine, wind power blows to a second-stage turbine fan blade after blowing through the first-stage turbine fan blade, the 2 nd small circle is lower than the 3 rd small circle and is used for installing the second-stage turbine, the first-stage turbine, the second-stage turbine, the high-power wind generating set and the permanent magnet gear transmission large flywheel form a power generation and energy storage device combination, and the utilization rate of the wind power is improved; the permanent magnet gear transmission large flywheel not only ensures the operation stability of the generator set, but also ensures the realization of the energy storage of the vacuum electromagnetic gear transmission energy storage flywheel and the compressed air of the vacuum electromagnetic gear transmission air compressor.
4. The high wind speed energy storage and low wind speed stable power generation system (fig. 14, 15 and 16, an intelligent power supply control system of a vacuum electromagnetic gear transmission energy storage flywheel and an electromagnetic gear transmission circuit, an intelligent power supply control system of a vacuum electromagnetic gear transmission air compressor and an electromagnetic gear transmission circuit, a matched cooling mechanism and a compressed air charging and discharging intelligent valve combination) is characterized in that the balance and stable power generation problem of the wind generating set under the condition of high wind speed and low wind speed is ensured in the system by the modes of energy storage flywheel frequency modulation and compressed air peak modulation, the problem of unstable power generation (generating garbage electricity) of the traditional wind generating set is solved, the storage of surplus wind energy except for normal high-level power generation is ensured at high wind speed, and the energy storage is instantaneously released at low wind speed to ensure that the wind generating set can still keep high-level normal power generation at low wind speed.
(1) Under the condition of high wind speed (when the wind generating set generates surplus wind energy outside normal high-level power generation), the vacuum electromagnetic gear transmission energy storage flywheel intelligent power supply control system preferentially supplies power to an electromagnetic gear circuit of the vacuum electromagnetic gear transmission energy storage flywheel, and the wind driven generator permanent magnet gear transmission large flywheel dumps energy to the vacuum electromagnetic gear transmission energy storage flywheel;
(2) under the condition of high wind speed II (when surplus wind energy still exists after the wind generating set normally generates electricity at a high level and dumps energy to the vacuum electromagnetic gear transmission energy storage flywheel through the wind generator permanent magnet gear transmission large flywheel);
(3) during the valley power period, when the power is surplus, the commercial power supplies power to the vacuum electromagnetic gear transmission air compressor, and the air is compressed by the compressor to store energy;
(4) under the condition of low wind speed (when the wind generating set cannot maintain normal high-level power generation at low wind speed), the vacuum electromagnetic gear transmission energy storage flywheel intelligent power supply control system preferentially supplies power to an electromagnetic gear circuit of the vacuum electromagnetic gear transmission energy storage flywheel, and the vacuum electromagnetic gear transmission energy storage flywheel dumps energy to a permanent magnet gear transmission large flywheel of the wind generating set;
(5) and in the case of low wind speed (when the wind generating set cannot maintain normal high-level power generation at low wind speed and still cannot maintain normal high-level power generation by dumping energy to a permanent magnet gear transmission large flywheel of the wind generating set through a vacuum electromagnetic gear transmission energy storage flywheel), a compressed air storage valve switch is opened through a compressed air inflation and deflation intelligent valve combination, and compressed air is released to a turbine through 4 groups of symmetrical compressed air pipelines leading to the turbine to maintain normal high-level power generation of the wind generating set at low wind speed.
