Description
Technical field
It the present invention relates to the use of the power generator field that external kinetic energy generates electricity, and in particular to one kind has multiple power generations
The generator and its progress control method of unit.
Background technique
With the development of industrial and agricultural production and the raising of living standards of the people, generate electricity now with renewable energy
Technology receives more and more attention.Existing frequently-used generator is definite value generator, and specified operational forces are usually inputted to it
Square and nominal operation revolving speed, generator export rated operational voltage, rated frequency and rated power.Above-mentioned definite value generator is to defeated
The torque and revolving speed requirement entered is relatively high, therefore there is a problem of in terms of being generated electricity using renewable energy obvious.
Common renewable energy includes wind-force, tide etc., the power input that these energy provide all be it is unstable, it is existing
The wind energy for having wind-driven generator to be utilized is usually to be confined to certain range using section, inputs nothing to the power outside application section
Method is efficiently used, and is caused low to renewable energy utilization rate.Such as existing large-scale wind driven generator, usually by one
A rated power 1000KW or so powerful electricity generation module constitute, usually only wind-force reach Pyatyi, six grades and with
On large wind Shi Caike with normal power generation and export standard compliant electric current, and in second level to the low wind of level Four, gentle breeze section, outside
The input of portion's power and power input are typically not enough to drive generator normal power generation, even if power generation, output is also not meet one
Determine the useless electricity of frequency, voltage standard, thus make generator be chronically in the case where lower wind speed stop, idle state, because
And such large-scale wind driven generator is only limited to the lesser big wind-force section of an application range to the utilization of wind-force.
In addition, extraneous wind-force is because of its unstability, under too small wind-force generator generally can not normal power generation, therefore wind
Power generator would generally set a start-up parameter for example rotary speed parameter, only just start when wind speed reaches certain standard
Generator normal power generation, but starting electrical power generators in a flash, because generating the electric current of moment in the coil part of generator
Reactive torque of the momentary action on main power shaft can be thus generated, will appear one in the moment of starting generator in this way
Significant Caton phenomenon, this Caton phenomenon would generally seriously damage the mechanical component of generator and generate huge noise,
If such case will persistently seriously affect the normal operation and service life of generator for a long time under unstable wind behaviour,
Maintenance cost is very high.
Thus, how to make generator in the different application Duan Junneng normal power generation of external impetus, and in generator starting
Not occurring significant Caton phenomenon is particularly important.
Summary of the invention
In view of the above technical defects, the present invention provides it is a kind of by it is multiple can the power generation that forms of independently operated generator unit
Machine, the generator can participate in power generation according to the generator unit for the variation and size control different number that external impetus inputs, thus
It can effectively realize the different application Duan Junke normal power generation in external impetus, the particularly important is and sent out before starting normal power generation
Motor has adaptive and gentle transition a process, occurs significant Caton phenomenon on startup so as to avoid generator,
The service life for greatly extending generator, reduces maintenance cost.
Basic technology scheme of the invention is a kind of generator with multiple generator units, comprising:
Motor housing, main power shaft；
It is sequentially connected in series multiple generator units on main power shaft；Each generator unit includes a unit magnet portion
With a unit coil portion；The unit magnet portion can rotate the rotor for constituting generator, the unit coil with main power shaft
The stator of portion's composition generator；
Control system, the control system include controller, signal acquisition transmission module, signal acquisition transmission module and control
Device signal connection processed, controller controls each generator unit according to the signal from signal acquisition transmission module received respectively joins
With power generation；
One of generator unit is start unit, in the signal from signal acquisition transmission module that controller receives
Before meeting entry condition, the start unit and extraneous load conduction are to generate the reactive torque acted on main power shaft；
When the signal from signal acquisition transmission module that controller receives meets entry condition, controller can control the starting list
Member participates in generating electricity and exports the electric current for meeting established standards.
The main power shaft can be direct or indirect connection external impetus mechanism for example wind-driven generator blade main shaft,
Main power shaft runs through the shell of generator and is fixed with shell both ends by bearing, and usual main power shaft is one, can also root
More main power shafts are arranged according to situation and are driven by gear set；The controller is PLC controller or intelligent controller；It is multiple
Generator unit refer to it is two or more can independently operated generator unit, each generator unit is respectively provided with respective volume
Determine power, the rated power of usual each generator unit be it is identical, the maximum rated power of generator is the volume of each generator unit
Determine power sum.Multiple generator units are sequentially connected in series refers to that multiple generator units are successively arranged sequentially on main power shaft
On main power shaft, each generator unit is allowed to receive the external impetus of main power shaft transmitting simultaneously.
The signal acquisition transmission module includes a speed measuring coder or torque sensor or voltage sensor or electric current
Sensor or power sensor, to acquire the operating state signal of generator and be transferred to controller, these signals be can be
The power signal of some generator unit, voltage signal, current signal or main power shaft tach signal, torque value letter
Number etc., it is also possible to the complete machine signal of generator, these signals can embody the operating status of generator, can be used as sense
Know the size of external impetus input and the signal of variation.Control parameter can be previously entered in controller to according to input
Signal Regulation control participates in the quantity of the generator unit of power generation and the rated power of generator, so that the generator can be according to outside
The variation of power input and the generator unit of size control different number participate in power generation, so as to effectively realize in external impetus
Different application Duan Junke normal power generation.
Particular, it is important that start unit can be set as one of generator unit of generator, so that generator opens
There is adaptive and gentle transition a process before dynamic normal power generation.
The operation principle of the present invention is that: control parameter is set in controller, including an entry condition (parameter),
Generator main power shaft starts turning under external power drive, and the unit magnet portion and main power shaft of the start unit are fixed to be connected
It connects and with its synchronous rotation, before the signal that controller receives meets entry condition, the unit coil portion of the start unit
Output circuit be also always that can be battery with extraneous load conduction, the extraneous load of conducting or be directly grounded, because
And as the unit coil portion of stator can confrontation unit magnet portion make cutting magnetic line movement and generate electric current, in this way lesser
There is certain electric current always in the unit coil portion of the start unit when external impetus inputs, although these current values are not met
The standard of output, power supply, but these always existing relatively small electric current make the start unit starting normal power generation it
It is preceding to generate a reactive torque (being equivalent to one reversed resistance of main power shaft of rotation) acted on main power shaft always,
The reactive torque can balance the positive torque that the external impetus of input generates on main power shaft, and the reactive torque is exhausted
The variation of the absolute value for the positive torque that value is generated with external impetus and change, and the two often gradually tend to balance so that
The sum of the torque vector obtained on main power shaft is zero, so that main power shaft revolving speed maintains at the uniform velocity state.So-called positive torque is
The torque for the driving rotation that external power effect generates on main power shaft, so-called reactive torque is the electric current in unit coil portion
With the electromagnetic induction of unit magnet portion and acting on for generating torque on main power shaft, opposite with positive torque.Work as outside
Power and its torque value incrementally increase, and revolving speed incrementally increases, then the electric current in the unit coil portion of start unit also increases with it,
The reactive torque value that thus start unit generates also increases with it, conversely, the reactive torque value that start unit generates is dynamic with outside
Becoming smaller for power and become smaller.
Therefore, before the signal that controller receives meets entry condition, which is in can be with external impetus
The state of size free-running operation and generation act on reactive torque on main power shaft, changing with external impetus and change.When
External impetus input it is sufficiently large, for example meet when the signal that controller receives meets entry condition main power shaft tachometer value or
The current value of a certain generator unit, performance number, then controller control cuts off the start unit and the extraneous original circuit of load simultaneously
The output circuit for controlling the start unit simultaneously is connected with the power supply circuit for external normal power supply, then the start unit participates in
It generates electricity and externally exports the electric current for meeting established standards, it is for example grid-connected to power or meet power requirement to industrial and mining enterprises' offer
Electric current, thus normal power generation.Because start unit before normal power generation its always with extraneous load conduction, always exist one
The reactive torque of real-time change with external impetus and positive torque variation, thus start normal power generation and defeated in the start unit
The electric current for meeting established standards out in a flash, acts on the sum of vector of positive torque and reactive torque on main power shaft
Variable quantity is very little, thus generator may be implemented from the free-run state before starting power generation to normal power generation state
Gentle transition occurs significant Caton phenomenon so as to avoid generator on startup.With the increase of external impetus, active force
The revolving speed and positive torque of axis continue growing, when reaching certain control parameter, controller control load it is one or more its
He participates in power generation by generator unit, so that the nominal total power of generator output increases.
When external impetus is reduced to certain control parameter, controller control unloading one or more has participated in the hair of power generation
Electric unit, thus, the big minor adjustment that controller can be inputted according to external impetus participates in the quantity and power generation of the generator unit of power generation
The rated power of machine, thus generator can be adapted to different application section external impetus and can normal power generation work.
Each generator unit of the present invention includes start unit " participating in power generation ", means that the electricity of output meets certain electricity
Pressure, frequency standard, can satisfy power supply, power demand, that is, usually said normal power generation, including meet industrial and mining enterprises etc.
The electric current of Subscriber Unit power demand standard can also be the electric current for meeting externally grid-connected condition of power supply.
In order to which more convenient each generator unit of control participates in power generation, the unit magnet portion is fixed with main power shaft respectively
Connection, the controller pass through the conducting for controlling each unit coil portion output circuit respectively and participate in hair to control generator unit
Electricity.This structure rotates synchronously the unit magnet portion of each generator unit all with the rotation of main power shaft, in unit coil
Potential is only generated in the case that the output circuit in portion does not turn on, in unit coil portion without generating electric current, because working as list without generating electricity
When the output circuit conducting of first coil part, then the potential will form electric current so as to participate in sending out in unit coil portion
Electricity.Therefore, only needing the conducting of the output circuit of control unit coil part can easily control whether each generator unit participates in sending out

Whether unit, which participates in, generates electricity, for this purpose, an electromagnetic clutch, each electromagnetic clutch need to be configured in each unit magnet portion
Device is fixedly connected with main power shaft respectively, controller by control electromagnetic clutch combination with separate with control unit magnet portion
Rotation, thus control generator unit participate in power generation.This control mode compares the conducting of control unit coil part output circuit,
, in the presence of structure is complicated, control is complicated for it, at high cost, in conjunction with various disadvantages such as not firm, fever skidding, failure rate height, but its
It is a kind of selectable scheme.

For direct current, direct current is then converted to by standard compliant alternating current by inverter again, so as to external grid-connected power supply
Or it directly uses.
The generator unit altogether there are four or five.If generator unit is too many, it will cause part generator unit and be in length
There is investment waste in the idle state of time；Generator unit is unfavorable for the effective use to external impetus again very little, therefore generates electricity
The quantity of unit is advisable with four or five, such ratio for input and output highest, economic benefit highest.
It advanced optimizes, the extraneous load is battery, and the unit coil portion of the start unit can be with battery electricity
Connection, is in series with battery switch module between the unit coil portion and the battery, the battery is to store the starting
The electric current for not meeting outputting standard that unit generates.After the alternating current that the start unit generates is converted to direct current by rectifier
Battery is inputted again.The main function of this structure is, before the signal that controller receives meets entry condition, starting
The output circuit of unit with as the external world load battery be electrically connected conducting, thus can both allow start unit generation one with

C, controller controls other each power generations according to the signal from signal acquisition transmission module received respectively
Unit participates in power generation.
Further, in step C, when the signal of signal acquisition transmission module feedback meets a loading environment, control
Device control loads a generator unit and participates in power generation；When the signal of signal acquisition transmission module feedback meets a unloading condition
When, controller control unloading one has participated in the generator unit of power generation.For example, when the revolving speed of main power shaft increases up to controller
When one revolving speed upper limit value of interior setting, it is meant that the input of external impetus has been more than the generator unit of original quantity in normal work
Bearing capacity when making, it is therefore desirable to it loads a generator unit and participates in generating electricity jointly, one power generation of conducting of controller control at this time
The output circuit in the unit coil portion of unit then generates electric current and participates in generating electricity jointly, thus in active force inside the generator unit
A reactive torque is increased on axis, then the revolving speed of main power shaft is down to original range；Otherwise when the revolving speed of main power shaft reduces
When reaching the lower rotation speed limit value set in controller, then mean that the input of external impetus is not enough to drive original quantity
Generator unit normal power generation, it is therefore desirable to unload the generator unit for having participated in power generation, controller control at this time disconnects one
The output circuit in the unit coil portion of generator unit then no longer generates electric current thus reduces and act on master inside the generator unit
Reactive torque on line shaft, then the revolving speed of main power shaft rises to original range.So generator main power shaft revolving speed is tieed up
Hold the normal power generation in a normal working range.
The entry condition can be a spin speed value or torque value or current value or voltage value or performance number, institute
The control parameter stated can be a spin speed value corresponding with entry condition or torque value or current value or voltage value or
Performance number.The control condition that power generation is participated in for controlling other generator units of the entry condition and controller of start unit can be
It is identical, it is preferably identical, established standards and simplified control condition can be unified in this way.
