Embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, the utility model is the driving chain of wind driven generator device with torque compensation function, be made up of impeller 1, planetary stage, two-stage parallel stage, servo-controlled motor 3, generator 12 and feedback control system 13, impeller 1 is connected by the planet carrier 2 of main shaft with gear-box expert star, planet carrier 2 drives three planet wheels 6, and planet wheel 6 is meshed with ring gear 5 and sun gear 7 simultaneously; Be connected in the left side of ring gear 5 first-class large external toothing, and servo-controlled motor 3 realizes engaging with external toothing by the first small gear 4 as torque compensation end; Sun gear 7 obtains first gear 8 by a longer axle with first order parallel stage and is connected, first gear 8 and the engagement of the second small gear 9 constitute first order parallel stage speedup, the second largest gear 10 of the second parallel stage and the second small gear 9 of the first parallel stage realize being synchronized with the movement on the same axis, gearwheel 10 and third pinion 11 engagement constitute second level parallel stage speedup motion, and third pinion 11 is arranged on gearbox output shaft.
As shown in Figure 1 and Figure 2, the first small gear 4 is driven by servo-controlled motor 3, is meshed with external toothing; Impeller end is the primary input end of transmission chain device, and servo-controlled motor is the torque compensation end of Transmitted chains, and generator 12 end is the output terminal of transmission chain device.
The utility model utilizes the auxiliary input of servo-controlled motor carry out control and compensation to primary input and export surplus power is auxiliary, keeps the invariablenes turning speed of transmission system output terminal.The effect of driving chain of wind driven generator is that the moment of torsion that wind wheel is changed is exported to generator after step-up gear, but the little rotating speed determining Transmitted chains transmission is also change time large during wind-force, therefore generated output power is unstable and be difficult to realize direct grid-connected generating.As shown in Figure 2, the utility model adds servo-controlled motor on traditional driving chain of wind driven generator basis.As shown in Figure 2, the ring gear of the utility model to original planetary system improves, and adds an external toothing be connected with it at the left end of ring gear 5, achieves the first small gear 4 and toothed ring gear 5 engages.Wind wheel is the primary input end of whole transmission chain system, servo-controlled motor 3 is auxiliary input/output terminal, generator 12 is main output terminal, by feedback control system 13 by the speed feedback of output terminal and primary input end to servo-controlled motor, when rated speed lower than unit operation of the rotating speed of primary input end-impeller 1, auxiliary port provides certain speed considerations input after feedback control system 13 converts, and ensures the invariablenes turning speed of generator port; When rated speed higher than system requirements of the rotating speed of impeller 1, traditional wind-driven generator limits the further capturing wind energy of wind wheel by change oar or other modes, do not limit wind wheel within the scope of the maximum wind speed round that this device allows at wind-driven generator and continue capturing wind energy, export auxiliary for auxiliary for the power utilization of surplus end after being converted by feedback control system 13 under ensureing the condition of main output terminal invariablenes turning speed, make servo-controlled motor as generator operation auxiliary power generation, thus decrease the loss of power.The power of primary input end is by wind wheel reformed gas power, mechanical energy is converted to after electric energy by output terminal direct grid-connected generator by Transmitted chains, there are three kinds of working staties in servomotor, is from electrical network acquisition electric energy using motorjbrm work respectively, does not work and provide electric energy three kinds of states as generator operation.
When the rotating speed that impeller 1 inputs is not enough to the rated speed reaching generator 12, primary input rotating speed and output speed are fed back to servo-controlled motor 3 by feedback control system 13, auxiliary input terminals is started working, servo-controlled motor 3 drives the first small gear 4 to engage with the ring gear 5 of planetary gear train, certain rotating speed is provided to ring gear 5, now superposed by the rotating speed of primary input and auxiliary input, after speedup box speedup, make rotating speed can reach the rated speed of generator 12 and stable electric generation; When wind speed exceedes wind-driven generator nominal operation wind speed, but still in unit operating rotational speed range, the primary input rotating speed now provided by impeller 1 exceedes rated speed, primary input rotating speed and output speed are fed back to servo-controlled motor 3 by feedback control system 13, the power of surplus, with generator mode, is exported by servo-controlled motor 3 and generates electricity by auxiliary input terminals; When the rotating speed that impeller 1 provides equals unit rated speed, after feedback control system 13 calculates, auxiliary input terminals quits work, and the ring gear 5 of planetary gear train keeps fixing, only as the engagement gear ring of planet wheel.Thus controlled by the output speed of these three kinds of working staties to Transmitted chains, output speed finally can be kept constant.
These three kinds of working staties of structure are distinguished by the operating characteristic of actuating motor.One, when the rotating speed of servo-controlled motor 3 be zero namely do not work time, system primary input end power all passes to main generator end except transmission loss; Its two, when servo-controlled motor 3 is as auxiliary input terminals, the summation of system primary input end power and actuating motor power all passes to main generator end except transmission loss; Its three, when servo-controlled motor 3 is as auxiliary output, the power of system primary input end, except transmission loss, is branched to main output terminal and actuating motor end.
