(5) yaw system: yaw system adopts initiatively wind gear drive form, with control system, matches, and makes impeller all the time in state windward, takes full advantage of wind energy, improves generating efficiency.
The speed of natural wind and direction are change at random, so wind energy has unsettled characteristics.Existing wind generating unit is to make stable output power also propose the method for multiple improvement, but there is no to solve the stable problem of wind driven generator output power at all.Other defect is exactly that wind generating unit is sent out electricity how many and just to electrical network, carried how many electricity, can not change and active accommodation by root tool electrical network user load.This is current wind generating unit and the maximum difference of other electricity generating device (fossil steam turbine electricity generating device, nuclear steam turbine electricity generating device, gas turbine generating set etc.), is also to cause the wind-powered electricity generation online to cause the maximum technical problem of electrical network shakiness.
In addition, due to current wind generating unit in order to improve the wind-powered electricity generation quality, a large amount of control techniques and power electronic equipment have been adopted, not only the complicated cost of mechanism is high, and can produce electric harmonic, and the electric energy power factor of sending is worsened, therefore the wind energy total amount generally be connected to the grid is no more than 10% of net capacity, " limit wind " and " abandoning wind " measure, because considering the stabilization of power grids, are had to take in many areas, and therefore very large economic loss is arranged every year.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcomings such as existing wind generating unit power is unstable, the Parallel Operation on Power System impact is large, the complex structure cost is high, wind energy utilization is low, not only stable output power is provided, can not impact electrical network, and the low wind energy utilization of cost is high, the grid-connected wind generating unit of a kind of compressed-air energy storage of safeguarding of being convenient to simple in structure.
The utility model is provided with fan blade, fan blade transmission shaft, driving gear, fixed gear transmission shaft, pylon, gear-box, compressor transmission shaft, High-Pressure Compressor, gas holder and steam turbine generator; Described fan blade is fixed on pylon by the fan blade transmission shaft, driving gear is fixed on the fan blade transmission shaft, fixed gear and driving gear engagement, fixed gear is fixed on the upper end of fixed gear transmission shaft, the lower end of fixed gear transmission shaft is connected with gear-box, gear-box is located on the pedestal of pylon bottom, the two ends of compressor transmission shaft are connected with High-Pressure Compressor with gear-box respectively, the high-pressure air outlet of High-Pressure Compressor is connected with the entrance of gas holder through gas pipeline, and the outlet of gas holder is connected with the suction port of steam turbine generator through gas pipeline.
It is unstable that the utility model has solved existing wind driven generator output power, causes the problem of electrical network shakiness when grid-connected, avoided " limit wind " " abandoning wind ".In addition, of the present utility model simple in structure, be convenient to safeguard.
The accompanying drawing explanation
Fig. 1 is that the utility model embodiment's structure forms schematic diagram.
Fig. 2 is the modular configurations sketch.
Embodiment
Referring to Fig. 1, the utility model embodiment is provided with fan blade 1, fan blade transmission shaft 2, driving gear 3, fixed gear transmission shaft 4, pylon 5, gear-box 6, compressor transmission shaft 7, High-Pressure Compressor 8, gas holder 10 and steam turbine generator 12, described fan blade 1 is fixed on pylon 5 by fan blade transmission shaft 2, driving gear 3 is fixed on fan blade transmission shaft 2, fixed gear 41 and driving gear 3 engagements, fixed gear 41 is fixed on the upper end of fixed gear transmission shaft 4, the lower end of fixed gear transmission shaft 4 is connected with gear-box 6, gear-box 6 is located on the pedestal of pylon 5 bottoms, the two ends of compressor transmission shaft 7 are connected with High-Pressure Compressor 8 with gear-box 6 respectively, the high-pressure air outlet of High-Pressure Compressor 8 is connected with the entrance of gas holder 10 through gas pipeline 9, the outlet of gas holder 10 is connected with the suction port of steam turbine generator 12 through gas pipeline 11.
