Description

The machine driven system of extra-large-size vertical-shaft wind power generation device
Technical field
The present invention relates to technical field of wind power generation, is a kind of mechanical conveyance system that the moment of rotation of vertical shaft generation is passed to many generators because of wind-force specifically.
Background technique
The axis body that extra-large-size vertical-shaft formula wind generating unit, very large characteristic are exactly vertical shaft is long, and self is heavy, installs and carry-over moment difficulty relatively.Add the unstability of wind speed, give the startup of electricity generating device and control a lot of problems of having brought.Particularly to take full advantage of wind energy, realize Electricity Generation, just must stablize the driving plurality generator and turn round simultaneously.Because the uncertainty of wind-force, the generator supporting with it or the operation torque that does not reach generator because wind-force is little is in the standby starting state; Wind-force has reached the operation torque of separate unit generator, but does not reach the detent torque of many generators, still can not start smoothly generating.So, the wind energy of power generation system is difficult to take full advantage of, and generating efficiency reduces greatly, and equipment can only be kept low-level operation.Therefore, stablize the rotating speed of vertical shaft, smooth starting and the normal operation of control motor, the rational machine driven system of design science just becomes the key that can extra-large-size vertical-shaft wind power generation device normally move generating.
Summary of the invention
The deficiency that exists in order to solve extra-large-size vertical-shaft formula wind power plant the invention provides a kind of according to wind-force variation, the machine driven system of the extra-large-size vertical-shaft wind power generation device that in real time each generator set is accessed successively.
The technical solution adopted in the present invention is: the machine driven system of this extra-large-size vertical-shaft wind power generation device, comprise vertical shaft, be fixed in central gear, generator and pedestal on the vertical shaft, it is that mainly said generator is set to vertical structure, and electrical axis is installed perpendicular to pedestal; Pedestal in the vertical shaft bottom is provided with the load-bearing bearing pack, by load-bearing bearing pack and spring bearing fixed vertical axis; By bearing 3～5 satellite gears that are connected with alternator shaft are set at the central gear periphery, central gear and satellite gear engagement connect 1～5 electric clipper control brake on the brake disc of central gear, and alternator shaft is provided with electric control clutch.
The present invention's major advantage compared with prior art:
The one, novel structure, reasonable in design.Generator is set to vertical structure, and electrical axis is installed perpendicular to pedestal; Periphery at central gear arranges 3～5 satellite gears that are connected with alternator shaft, and central gear and satellite gear are flexibly connected.The improvement of these structures has fundamentally solved the bottleneck problem that exists in the extra-large-size vertical-shaft wind power generation.The vertical shaft lower end is connected with central gear through large-sized flange, and central gear is supported by the bearing pack that places pedestal, and the load on the vertical shaft and the gravity of central gear also are that thrust load is by the load-bearing bearing pack carrying that places base bottom.Windmill rotates central gear in the torque that produces under wind-force effect end flange under vertical shaft, the symmetrical satellite gear of installing around central gear drives.Because satellite gear axle and generator input shaft are isolated by electric control clutch, so being empty load, whole gear transmission starts, make gear train easily finish startup.Along with rise of rotational speed, when reaching the setting rotating speed, sensor sends signal to computer, and computer is assigned wherein generator clutch of instruction closure.Because clutch adopts indirectly connected type, the satellite gear of this group passes to generator gradually with torque, makes generator finish stably start-up course.After the first unit was working properly, velocity transducer was found out the central gear rotating speed and is reached again when setting rotating speed, sends signal to again computer, and computer is again to giving an order with second unit on its opposite.Second clutch closure devoted oneself to work second generator set.When wind-force was enough large, all generators put into operation.During the abatement of wind, said process is oppositely carried out, and generator withdraws from successively.Thereby realized the taking full advantage of of wind energy improved generating efficiency, reached Electricity Generation.
The 2nd, security of operation is stable, reliable performance.Another characteristics of the present invention are behind whole generator normal operation inputs, if wind-force is still excessive, will make the central gear rise of rotational speed, affect the power generating equipment steady running.To compare this moment according to the data that program setting numerical value and velocity transducer send, and when greater than setting value, send the brake instruction to first electric clipper control brake.If the braking force deficiency is so that central gear moves by rated speed, control program will send instruction to second break with first break opposite setting and make its closure, and the rest may be inferred, until central gear moves according to rated speed.Effectively solved mechanical transmission problem in the large-scale vertical wind-power electricity generation, can be in the situation that the less smooth starting of wind speed even wind speed is larger, also can keep rated speed.

Embodiment
The invention will be further described below in conjunction with example.
As shown in Figure 1, the machine driven system of the extra-large-size vertical-shaft wind power generation device of this 1.2MW, comprise diameter d=600mm vertical shaft 1, be fixed on the central gear 2 on the vertical shaft 1, central gear 2 diameter d 1=4250mm, tooth number Z 1The generator 11 of=17,4 300KW and pedestal 9.Generator 11 is vertical structure, and the generator axis is installed perpendicular to pedestal 9; Pedestal 9 in vertical shaft 1 bottom is provided with load-bearing bearing pack 8, by load-bearing bearing pack 8 and spring bearing 7 fixed vertical axis 1.By bearing 6 correspondences 4 satellite gears 3 that are connected with generator 11 rotating shafts, satellite gear 3 diameter d are set at central gear 2 peripheries 2=425mm, tooth number Z 2=170, speed ratio i=10.Central gear 2 and 4 satellite gear 3 engagements.Central gear 2 is provided with 4 disc type brake dishes 10, and electric clipper control brake 5 is set on the brake disc 10, connects indirectly connected electric control clutch 4 in generator 11 rotating shafts.
Working procedure of the present invention is:
Under the wind-force effect, central gear 2 No Load Starts.When rotation speed n＞5rpm (getting speed ratio λ=0.8), electric control clutch 4 closed at the beginning, satellite gear 3 passes to generator 11 with the operation torque of 57.3KN, makes generator 11 produce the power stage of 300KW.When center gear 2 rotating speeds still＞during 5rpm, generator 11 opposite unit electric control clutch 4 closures that put into operation put into operation second 300KW generator 11.As long as wind-force reaches more than 3 grades or 3 grades, all the other generators 11 will put into operation by platform.If wind-force is larger, during central gear rotation speed n＞5rpm, 4 disc type electric clipper control brakes 5 will enter closed state automatically by platform, thus with central gear 2 stabilizations of speed at n=5rpm.If wind-force diminishes gradually, when central gear 2 rotating speeds are lower than rated speed, with disconnect by setup program the electric control clutch 4 of generator 11 by platform, make a generator 11 states out of service wherein.As long as windmill has the torque of 57.3KN, make central gear 2 keep rated speed, can guarantee that at least a generator 11 runs well.
