Description
Technical field
The present invention relates to a kind of closing method for wind power generating set, more particularly to a kind of fixed pitch wind-force that is used for send out
The closing method of group of motors.
Background technology
Wind-resources be it is a kind of have a high potential, the regenerative resource that technology is mature on the whole.In recent years, global resources environmental constraints
Aggravation, climate change become clear day by day, and wind-powered electricity generation is increasingly paid much attention to by countries in the world.
With respect to fixed pitch wind power generating set, the wind wheel system of pitch-controlled wind-driven generator group is complicated, it is costly,
Maintenance frequency is higher.Therefore, fixed pitch type wind wheel system is widely used in middle-size and small-size wind power generating set.Safely and it is stably
The important indicator of wind power generating set performance is weighed, for unit when occurring extremely, shutdown is to ensure unique side of unit safety
Formula.
Wind power generating set is in the case of strong wind, if shutdown action can not be completed normally, i.e., unit can not be by design
Flow reduces wind speed round, can cause the driving of unit.After unit exceedes the wind speed round allowed, first, serious machine can be caused
Tool damages：Blade in wind wheel system is damaged, and causes its center of the centre-of gravity shift of wind wheel, so as to cause the strong vibration of unit,
The significantly swing of set tower drum, this is to yaw system, brake system, wind wheel system, tower, or even whole unit causes to repair
Multiple destruction.Worst situation can cause collapsing for whole unit；Second, the life-span of unit electric part can be influenceed：Bus electricity
That flows is excessive, causes the overheat of generator, influences the life-span of generator, while causes controller high temperature, gently then causes controller
The damage of interior component, it is heavy then cause fire.In addition, except the harm to wind power generating set itself, wind-driven generator hypervelocity
Also serious threat the safety of unit surrounding population, building.
And the fixed pitch wind power generating set shutdown means for lacking change oar function are limited, fixed pitch wind power generating set is commonly used
Shutdown means have mechanical brake, drain charge, take shelter from the wind and electromagnetic braking.As shown in figure 1, they are according to certain permutation and combination, shape
Into specific control strategy, to reach the purpose of compressor emergency shutdown.In whole stopping process, according to the maximum moment curve of generator
Perform drain charge；Either the mark that action of taking shelter from the wind is completed is gone off course to 90 ° of wind direction positions for cabin, or it is driftage to relatively low wind wheel
Rotating speed；Mechanical brake is put at once typically after wind speed round reduces slightly；Finally treat that wind wheel is reduced to very low wind speed round
Afterwards, unit carries out electromagnetic braking, i.e. generator short circuit.
The shutdown strategy of above-mentioned traditional fixed pitch wind power generating set, the conventional shutdown of reply unit are no any ask
Topic.But a certain measuring system or a certain actuator failure when unit, cause any one hand in compressor emergency shutdown means
When Duan Wufa is normally carried out, i.e., after the failure of unit simple function, other brake tools of fixed pitch wind power generating set are made a concerted effort not
The wind energy for being enough to overcome wind wheel to obtain from wind is shut down.During wind vane failure, the beginning point of reference of driftage is just inaccurate, that
Unit is taken shelter from the wind according to this wrong beginning point of reference, and the angle of cabin and wind direction can be random angle after end of taking shelter from the wind
Degree；It is used in yaw system after calculating the sensor fault that angle has been walked in driftage, action of taking shelter from the wind can not be normally carried out, then now
Function of taking shelter from the wind just fails；During wind speed round measuring system failure, wind speed round measured value is excessive compared with actual value, mechanical brake,
Electromagnetic braking can not be normally carried out, and action of taking shelter from the wind can not normally complete.Wind speed round measured value is too small compared with actual value, mechanical brake
Too early input, this can cause the overheat of brake block, reduce the brake force of mechanical brake, it is irreversible to will also result in brake block
The bright phenomenon of heat.
Therefore, for fixed pitch wind power generating set, how shutdown action is safely and effectively completed, it is fast in stopping process
Speed, power coefficient is effectively reduced, reduce the seizure of unit wind energy, be the difficulty that those skilled in the art are directed to solving
Topic.
The content of the invention
The technical problem to be solved in the present invention is to be directed to fixed pitch wind power generating set, how safely and effectively to complete to shut down
Action.
In order to solve the above-mentioned technical problem, the technical scheme is that providing one kind is used for fixed pitch wind power generating set
Closing method, it is characterised in that：After triggering is shut down, unit performs shutdown flow at once, and the step of shutting down flow is as follows：
The first step：Flow of taking shelter from the wind in drain charge flow and stopping process while it is performed；
Second step：What if unit performed is emergency shutdown, or after shutdown triggering setting time, or wind speed round is less than setting
Value, unit perform mechanical brake flow；Crush trigger brake flow has individual premise, and wind speed round can not be more than 85RPM；
3rd step：After the execution of mechanical brake flow, if unit has over voltage alarm, generator short circuit contactor acts,
Short-circuit generator；After the completion of first three step performs, unit has completed shutdown action；
4th step, perform flow of taking shelter from the wind after the completion of shutting down；After flow of taking shelter from the wind after the completion of the shutdown end setup time, if
Wind wheel mean speed is more than setting value in 15s, then unit re-executes shutdown flow since the first step.
Preferably, in the first step, drain charge flow using by motor maximum output torque carry out drain charge by the way of, according to
The current rotating speed of wind wheel, busbar voltage, electric current, calculate drain charge system maximum goes out force, and real-time tracing wind speed round, mother
Line voltage, bus current, dynamically adjust drain charge and go out force, to reach the braking moment that drain charge system provides maximum in real time；Together
When drain charge flow add shutdown after the completion of, drain charge locking function, i.e., after unit normally completes shutdown, do not close drain charge stream still
Journey, and maximum braking moment is provided in real time with optimal operating point, after ensureing that unit normally completes shutdown, wind wheel is no longer
Unintentional rotation.
Preferably, in the first step, the purpose for flow of taking shelter from the wind in stopping process is to reduce wind speed round；Wind wheel is from wind
The wind energy of middle absorption
Pwind=(1/2) * Cp*ρ*Acosθ*V
Wherein, PwindThe wind energy absorbed for wind wheel from wind, CpFor power coefficient, ρ is atmospheric density, and A is wind wheel face
Product, θ is Windward angle, and V is wind speed；
From above formula, for Windward angle θ in 90 ° or 270 °, the wind energy that wind wheel absorbs from wind is 0；Therefore, as long as machine
Group successfully completes action of taking shelter from the wind, and compressor emergency shutdown can just normally complete.
It is highly preferred that in stopping process, after angular transducer failure has been walked in driftage, unit foundation is taken shelter from the wind the action executing time
Calculate driftage and walk angle；By this method after angular transducer failure has been walked in driftage, ensure the normal execution of action of taking shelter from the wind,
So as to reduce the probability for failure of taking shelter from the wind.
Further, the foundation take shelter from the wind the action executing time calculate driftage walked angle method be：Yawing velocity is permanent
Fixed, the product of yawing velocity and action executing time of taking shelter from the wind are that angle has been walked in driftage.
Preferably, for flow of taking shelter from the wind in stopping process, it is determined that the minimum stroke taken shelter from the wind is 135 °, because wind wheel exists always
Near prevailing wind direction, after stroke of taking shelter from the wind is more than 135 °, wind wheel must lean against prevailing wind direction.
Preferably, for flow of taking shelter from the wind in stopping process, consider that limitation of the tower cable stranded cable angle to action of taking shelter from the wind is asked
Topic：Before taking shelter from the wind, first confirm that whether the stroke in direction of taking shelter from the wind meets that the limitation of stranded cable angle requires；If being unsatisfactory for requiring, just to
Other direction is taken shelter from the wind, to ensure that unit secondary will not enter prevailing wind direction.
Preferably, flow of taking shelter from the wind after the completion of shutdown is to prevent unit from starting extremely again after normally completing shutdown；Stop
Take shelter from the wind during machine and action or take shelter from the wind after the completion of shutting down after action normally completes, every setting time, unit take shelter from the wind again to
90 °, unit is set to absorb excessive wind energy from wind.
Preferably, shut down in flow, when detecting mechanical brake input setting time, wind speed round can not be effectively reduced
Afterwards, mechanical brake is immediately unclamped, and after brake-block temperature reduction, mechanical brake is put into again, so as to ensure having for mechanical brake
Effect braking.
Preferably, shut down in flow, other operating modes in addition to bus overvoltage are without electromagnetic braking.
Method provided by the invention overcomes the deficiencies in the prior art, can not only tackle conventional compressor emergency shutdown, work as machine
After the simple function failure of each functional unit of group, unit remains to successfully complete shutdown action according to this method, safe.

Embodiment
With reference to specific embodiment, the present invention is expanded on further.It should be understood that these embodiments are merely to illustrate the present invention
Rather than limitation the scope of the present invention.In addition, it is to be understood that after the content of the invention lectured has been read, people in the art
Member can make various changes or modifications to the present invention, and these equivalent form of values equally fall within the application appended claims and limited
Scope.
Wind power generating set occurs abnormal unavoidable in the process of running, and shutdown is to prevent operating states of the units from continuing to dislike
The effective means of change.Fig. 2 is the closing method flow chart for fixed pitch wind power generating set that the present embodiment provides, described
Closing method for fixed pitch wind power generating set is specially：
After triggering is shut down, unit performs shutdown flow at once：
The first step, drain charge flow and stopping process, which are taken shelter from the wind, flow while to be performed；
Second step, if unit execution is emergency shutdown, or after shutdown triggering Δ T time (Δ T is the time of setting), or
Wind speed round is less than setting value R0, and unit performs mechanical brake flow；Crush trigger brake flow has individual premise, and wind speed round is not
85RPM can be more than；
3rd step, after the execution of mechanical brake flow, if unit has over voltage alarm, generator short circuit contactor acts,
Short-circuit generator；After the completion of first three step performs, unit has completed shutdown action；
4th step, perform flow of taking shelter from the wind after the completion of shutting down.Take shelter from the wind after the completion of shutdown terminate Δ T time (Δ T be setting when
Between) after, if wind wheel mean speed is more than setting value R0 in 15s, unit re-executes shutdown flow since the first step.
The difference master for the closing method and traditional closing method for fixed pitch wind power generating set that the present embodiment provides
It is embodied in following aspects：
1st, drain charge flow
Shutdown drain charge flow proposed by the present invention maintains maximum by motor in former stopping process than traditional drain charge flow
Output torque carries out the mode of drain charge：Drain charge system immediately enters drain charge flow after unit triggering is shut down.It is current according to wind wheel
Rotating speed, busbar voltage, electric current, calculate drain charge system it is maximum goes out force；And real-time tracing wind speed round, busbar voltage,
Bus current, dynamically adjust drain charge and go out force, reach the braking moment that drain charge system provides maximum in real time.The present invention's lets out
After the completion of lotus flow adds shutdown, drain charge locking function, i.e., after unit normally completes shutdown, drain charge flow is not closed still, and
There is provided the braking moment of maximum in real time with optimal operating point, after ensureing that unit normally completes shutdown, wind wheel is no longer unexpected
Rotate.
2nd, take shelter from the wind flow
Flow of taking shelter from the wind is divided into after the completion of take shelter from the wind in the stopping process shown in Fig. 3 flow and shutdown shown in Fig. 4 flow of taking shelter from the wind.
The purpose taken shelter from the wind in stopping process is to coordinate other means that wind speed round is reduced to relatively low rotating speed.Wind wheel is from wind
The wind energy of middle absorption
Pwind=(1/2) * Cp*ρ*Acosθ*V
Wherein, PwindThe wind energy absorbed for wind wheel from wind, CpFor power coefficient, ρ is atmospheric density, and A is wind wheel face
Product, θ is Windward angle, and V is wind speed.
It is not difficult to find out by above formula, when Windward angle θ is near 90 ° or 270 °, the wind energy that wind wheel absorbs from wind is almost
0.Therefore, as long as unit successfully completes action of taking shelter from the wind, compressor emergency shutdown can just normally complete.
But because set yaw speed is slow, therefore during unit is taken shelter from the wind, unit need to clamp down on wind wheel by other means and turn
Speed.It can be said that the success or not of the action that focuses on taking shelter from the wind of this strategy.Therefore, the present invention shuts down flow and has considered driftage
After walking angular transducer, wind transducer, wind speed round sensor, driftage driving failure, how to ensure the normal of action of taking shelter from the wind
Perform, so as to greatly reduce the probability for failure of taking shelter from the wind：After angular transducer failure has been walked in driftage, unit is according to action of taking shelter from the wind
Perform time calculating driftage and walked angle (yawing velocity is constant, and the product of speed and time are driftage stroke)；In order to ensure wind
To and wind speed round sensor failure after, action of taking shelter from the wind can perform exactly, and the minimum stroke taken shelter from the wind is determined in algorithm
135°.Because wind wheel is always near prevailing wind direction, after stroke of taking shelter from the wind is more than 135 °, wind wheel must lean against prevailing wind direction.
In addition, present invention additionally contemplates that restricted problem of the tower cable stranded cable angle to action of taking shelter from the wind, before taking shelter from the wind first
Confirm take shelter from the wind direction stroke whether meet stranded cable angle limitation require, if being unsatisfactory for requiring, just take shelter from the wind to other direction, with
Ensure that unit secondary will not enter prevailing wind direction.
Take shelter from the wind after the completion of shutdown is to prevent unit from starting extremely again after normally completing shutdown.Take shelter from the wind in stopping process
Action or after taking shelter from the wind and normally complete after the completion of shutting down, after Δ T time, unit is taken shelter from the wind to 90 ° again, makes unit can not possibly be from
Excessive wind energy is absorbed in wind.Δ T is the time of setting.
3rd, mechanical brake
Traditional mechanical brake is put into after wind speed round is reduced to certain value, but after wind speed round is lifted again, machine
Tool brake is not cut out.But if after mechanical brake input, if wind wheel can not be braked effectively, the temperature of braking mechanism
Degree can be raised rapidly；According to the intrinsic characteristic of brake block, mechanical brake torque can rapidly reduce with the rise of temperature.This
The lasting brake of sample can not only provide brake torque well, can also cause the expendable heat of mechanical brake to burn and damage,
The rise of cabin temperature can be more caused, threatens the safety of other components cabin Nei, or even causes catching fire in cabin.
Therefore, in shutdown flow of the invention, when detecting mechanical brake input a period of time, wind speed round can not be effective
Reduction after, mechanical brake immediately unclamp, after brake-block temperature reduction after, mechanical brake is put into again, so as to ensure mechanical brake
The effective brake of car.
4th, electromagnetic braking
The automatic short-circuit of the electromagnetic braking of unit, i.e. generator, after wind speed round is reduced to certain rotating speed, it can be very
Good offer braking moment.The electromagnetic braking of unit can be caused by measuring generator side Current Voltage frequency the wind wheel that measures
Rotating speed can not measure.Start if wind wheel is abnormal again after electromagnetic braking, and by chance now mechanical wind speed round sensor
Failure, unit is to be unaware of wind wheel to have rotated, and thus can cause the driving of unit.
Therefore, other operating modes that shutdown flow of the invention removes bus overvoltage are without electromagnetic braking.
To sum up, wind power generating set occurs abnormal unavoidable in the process of running, and shutdown is to prevent operating states of the units
Continue the effective means deteriorated.Show through overtesting, it is single in each functional unit that method provided by the invention can improve unit
The probability of shutdown is normally completed after failure, there is superiority in secure context.
The closing method for fixed pitch wind power generating set that the present embodiment provides can not only tackle conventional unit
Shut down, after unit simple function fails, after unit performs shutdown according to this closing method, unit remains to successfully complete to stop
Motor-driven work.
