Abstract
A power grid generator of wind force consists of blade, hub, gearbox, yaw, permanent-magnet synchronous generator and synchronous generator. It is featured as connecting gear shaft of gearbox to one end shaft of permanent-magnet synchronous generator, connecting another end shaft of permanent-magnet synchronous generator to shaft of synchronous generator.
Description
One, technical field
The present invention relates to a kind of wind power generator incorporated in power network, belong to the power generation field.
Two, background technique
Wind power generator incorporated in power network has many types now, and wherein traditional model has cage type asynchronous generator, magneto alternator, synchronous generator, double-fed asynchronous generator.
1, cage type asynchronous generator only could generate electricity under rated speed, and the generator operation time is short, and generated energy is little.
2, magneto alternator and synchronous generator are made generally in directly driving type, and motor diameter is very big, owing to all participate in inversion, and commutation inversion price height, but under any rotating speed, can both generate electricity the efficient height.
3, double-fed asynchronous generator can speed governing, can generate electricity in the certain limit rotating speed, and cost is moderate, but generator has slip ring, influences the motor reliability and increases the maintenance of motor cost.
Three, summary of the invention:
The technical problem that the present invention solves is: the wind speed of high-speed wind power generator is adjustable, can generate electricity when being lower than rated wind speed, and volume is little, good reliability, and maintenance cost is low, makes easily when high-power.
The purpose of this utility model is realized by following mode:
Technical solution: it is made up of blade, wheel hub, gear-box, driftage, magneto alternator, induction generator, gear shaft on the gear-box is connected with magneto alternator one end axle, and magneto alternator the other end axle is connected with the asynchronous generating arbor.
Gear shaft also can join with induction generator and then be connected with magneto alternator.
Magneto alternator and induction generator place in the support, shared rotating shaft, bearing, end cap.
Magneto alternator can adopt three-phase or heterogeneous.
Magneto alternator also can adopt various numbers of pole-pairs.
The utility model has the advantages that:
1, wind-driven generator can generate electricity by way of merging two or more grid systems under any rotating speed;
2, power factor height, magneto alternator can compensate the certain power factor when induction generator is worked.
3, owing to there is not slip ring, safeguard more convenient.
4, owing to be that magneto alternator partly needs inversion, the inversion cost is low, makes easily when high-power.
Four, description of drawings
Accompanying drawing is a structural representation of the present invention;
Five, embodiment:
The present invention is made up of blade 1, wheel hub 2, gear-box 3, driftage 4, magneto alternator 5, induction generator 6, the gear shaft of gear-box 3 is by being connected with magneto alternator 5 one end axles, and magneto alternator 5 the other end axles are connected with 6 of induction generators.
Magneto alternator 5 of the present invention, induction generator 6 have different running statees under different wind speed.After blade 1 starting, but rotating speed is surfed the Net by inverter after magneto alternator 5 operations and the rectification when being lower than rated wind speed.When wind speed increase wind speed round reached rated speed, induction generator 6 was cut electrical networks and is generated electricity by way of merging two or more grid systems jointly with magneto alternator 5.After wind speed weakened blade 1 rotating speed and is lower than rated speed, induction generator 6 cut out electrical network, and magneto alternator 5 still generates electricity by way of merging two or more grid systems.
Permanent magnet generator 5 is by being incorporated into the power networks behind the commutation inversion.So magneto alternator can adopt three-phase or heterogeneous, number of pole-pairs also can adopt various numbers of pole-pairs.
