Description
Technical field
This utility model relates to wind-power electricity generation and controls technical field, specifically, is to use double-fed management mode
And based on CAN control wind generator system.
Background technology
Wind energy, as the regenerative resource of a kind of cleaning, is increasingly paid attention to by countries in the world.Its amount of accumulateing is huge
Greatly, the wind energy in the whole world is about 2.74 × 109MW, the most available wind energy is 2 × 107MW, compares the earth
On the water energy total amount that can develop also want big 10 times.
Wind is utilized by people very early, is mainly drawn water by windmill, flour milling etc., and present, and people feel
Interest is how to use wind to generating.
THE WIND ENERGY RESOURCES IN CHINA is enriched, the wind energy content that can develop about 1,000,000,000 kW, wherein, and land windward
Energy storage capacity about 2.53 hundred million kW (land is liftoff 10m height material computation), sea can development and utilization

Standardized serial communication protocol.In automobile industry, for safety, comfortableness, convenience, low
Public hazards, the requirement of low cost, various electronic control systems are developed.Due to these systems
Between communicate data type used and the requirement to reliability is not quite similar, situation about being made up of multiple bus
A lot, the quantity of wire harness is consequently increased.For adapting to " reducing the quantity of wire harness ", " by multiple
LAN, carries out the high-speed communication of mass data " needs, the exploitation of electrically business Bosch of Germany in 1986
Appear the CAN communication agreement to automobile.Hereafter, CAN is carried out by ISO11898 and ISO11519
Standardization, has been the standard agreement of automotive networking in Europe.
The high-performance of CAN and reliability are admitted, and are widely used in industrial automation, ship
The aspects such as oceangoing ship, armarium, industrial equipment.Fieldbus is the focus of nowadays automatic art
One of, it is described as the LAN of automatic field.Its dcs that appears as realizes each
Between node, data communication real-time, reliable provides strong technical support.
CAN belongs to the category of fieldbus, and it is a kind of effective support distributed AC servo system or controls in real time
Serial communication network.For the dcs built based on R line than many RS-485, based on
The dcs of CAN has obvious superiority in the following areas:
CAN controller works in various ways, and each node in network all can be according to bus access priority
(depending on message identifier) uses the mode of the bit-by-bit arbitration of lossless structure to compete and sends data to bus,
And CAN protocol abolished station address coding, and instead encoding communication data, this can make difference
Node be simultaneously received identical data, each node of network that these features make CAN constitute it
Between data communication real-time, and easily constitute redundancy structure, improve the reliability of system and system
Motility.And utilizing RS-485 can only constitute primary and secondary structure system, communication mode also can only be taken turns with main website
The mode ask is carried out, and the real-time of system, reliability are poor；
CAN by two outfan CANH of CAN transceiver interface chip 82C250 and
CANL is connected with physical bus, and the state of CANH end can only be high level or suspended state, CANL
End can only be low level or suspended state.This ensure that will not in the phenomenon in occurring in RS-485 network,
I.e. wrong when system, multinode occurs simultaneously when bus sends data, cause bus to present short circuit, from
And damage the phenomenon of some node.And CAN node have in the case of mistake is serious be automatically switched off defeated
Go out function, so that the operation of other nodes is unaffected in bus, thus ensure not have as at network
In, because respective nodes goes wrong so that bus is in " deadlock " state.And, CAN has
Perfect communication protocol can be realized by CAN controller chip and interface chip thereof, thus be substantially reduced and be
System development difficulty, shortens the construction cycle, and these are that the RS-485 institute of only electrically agreement is incomparable
's.
It addition, with other fieldbus comparatively, CAN is that to have traffic rate high, easily real
A kind of fieldbus having formed international standard of the various features such as existing and cost performance is high.These are also
CAN is applied to various fields, has the major reason of the powerful market competitiveness.
CAN i.e. controller local area network, belongs to the category of industrial field bus.With general communication bus
Comparing, the data communication of CAN has prominent reliability, real-time and motility.Owing to it is good
Performance and the design of uniqueness, CAN is increasingly subject to people's attention.

There is the symmetrical threephase source excitation of fixed frequency.Electric machine rotor number of poles is identical, and rotor windings is by have can
The symmetrical threephase source excitation of regulating frequency；The rotating speed of motor is determined by the slip frequency between rotor.Electricity
The rotor magnetic field of machine is synchronous rotary, and therefore it has again the characteristic of similar synchronous motor.
When motor stator symmetry three-phase windings is by frequency f1Electrical network when powering, first-harmonic rotating excitation field in air gap
Synchronous rotational speed is n1, meet f1=npn1/60.Rotor is driven by prime mover with rotating speed nrRotate, and at rotor
Imposing frequency in symmetrical three-phase windings is sf1The variable-frequency power sources of (s is revolutional slip), produces three-phase in the rotor
Symmetrical current, the first-harmonic rotating magnetic potential F that they produce2With slip speed sn for rotor1Rotate,
Rotate with synchronous rotational speed relative to stator.The first-harmonic rotating excitation field that rotor magnetic potential is set up in air gap, at stator
(frequency is f to produce induced potential in winding1), this electromotive force is with the supply voltage added to outward in stator winding altogether
Same-action forms three-phase symmetrical electric current, consequent stator fundamental magnetic potential F1Rotate with synchronous rotational speed equally.
Rotor magnetic potential geo-stationary, forms composite magnetic power in air gapThis magnetic potential produces synthesis in air gap
Magnetic field Ψm, interlink with Stator and Rotor Windings respectively, be respectively induced electromotive force in the windings(frequency is
sf1)。
Substantially, double-fed speed-variable frequency-constant wind-driven generator is consistent with the operation principle of common asynchronous moter
's.The difference of the two is that the frequency of common asynchronous moter rotor current depends on the rotating speed of motor, by rotor
The frequency of short-circuiting bar induced potential determines, relevant with revolutional slip, the frequency of rotor current itself can not be autonomous
Ground, adjust artificially.And the frequency of double fed electric machine rotor winding is powered by additional ac excitation power supply, its frequency
Rate can change regulation therewith.Therefore, double feedback electric engine had both had the operation principle of asynchronous machine, had again same
The operating characteristic of step motor, is a kind of special asynchronous machine with synchronizing characteristics.
Use double-fed management mode, and apply variable speed constant frequency technology, rotating speed can be regulated on a large scale, make wind energy profit
It is maintained at optimum with coefficient；Can absorb and storage fitful wind energy, reduce fitful wind impact and wind-driven generator is produced
Raw fatigue damage, mechanical stress and torque pulsation, extends unit durability, reduces noise；The most controlled it is shaped with
Merit power and reactive power, improve the quality of power supply.
