Put the start and stop and protection for being mainly used in electromotor, LCU control panels be mainly used in the hydraulic turbine, electromotor, subsidiary engine, transformator, bus,
The control of chopper, disconnecting switch, grounding switch etc.;In water power station control system, although low voltage generator protection device and
LCU screens cabinet can realize automatically controlling and its miscellaneous equipment on-line monitoring and long-range control for low voltage generator to a certain extent
System, but, in generator active power and reactive power are adjusted, it is still desirable to which power station duty personnel is according to electric station water storage level
Situation judging the output with manual regulator generator, and in some equipment for not possessing data recording function,
The transient data and its parameter of operation that power station is broken down cannot all be preserved, it has not been convenient to the maintenance of unit and plant load
Analysis.
So that generating set power is adjusted as an example, it is well known that hydroelectric generation, the output of its electromotor is mainly by former dynamic
What power was determined, motive power is determined by guide vane opening and height of water level, i.e., guide vane opening is bigger, water level is higher, and motive power is bigger;
Analyze in theory, under the maximum power generation that electromotor itself can bear, lead the output of the bigger electromotor of leaf divergence
Power is bigger, but on the other hand guide vane opening determines the size of water yield again, if that is, water yield is more than cistern upstream
Inflow, then water-retention pool water level persistently can reduce, when being reduced to which and can not produce enough motive power, electromotor was by sending out originally

The intelligent operation method of above-mentioned power station low voltage generator intelligent operation device is:Power station low voltage generator intelligence
Running gear by level sensor sensed water level height, by processor MCU by the judgement to cistern current level from
It is dynamic to adjust power station low voltage generator guide vane opening, to generated output optimizing regulation:When monitoring that water level rises, water power
Low voltage generator intelligent operation device of standing control increases electromotor guide vane opening, increases water yield so that water level is maintained to one
New dynamic equilibrium point, lifts generator prime power, increases electromotor water power;Power station when water level decreasing
The control of low voltage generator intelligent operation device reduces guide vane opening, reduces water yield so that water level maintains new dynamic equilibrium
Point, allows electromotor continuous service in power generation mode, keeps the generated output in power station, make power station low voltage generator generated output
Automatization is adjusted, and optimizes the generated output of electromotor.
In above-mentioned technical proposal, specific practice is:When displacement and inflow reach balance, guide vane opening is in power station
X, the Water level trend balance height of cistern is H;When a certain moment upstream discharge increases, intelligent operation device is in the unit interval
Inside monitor that the real time water level H1 of cistern is in propradation, i.e. H1-H>0, then it represents that can increase and lead leaf divergence, increase
The generated output of electromotor;Increase guide vane opening x1 after electromotor guide vane opening is adjusted, it is necessary to which satisfaction can keep water-retention
The dynamic equilibrium of pool water level, i.e. cistern inflow and water yield are equal, so just can guarantee that and will not adjust because of guide vane opening
It has suffered big and water level decreasing occurs;In the same manner, when a certain moment upstream discharge is reduced, intelligent operation device is within the unit interval
Monitor that the real time water level H1 of cistern is in decline state, i.e. H1-H<0, it is to keep electromotor continuous firing in generating state,
Reduction electromotor is needed to lead leaf divergence, on the one hand guide vane opening x2 after adjustment needs satisfaction that Water level trend can be kept to put down
Weighing apparatus, on the other hand also needs to meet water level balance point and is not less than warning line point, and the water level point is critical site, if continued
Less than this water level point, generator prime power deficiency is likely to occur absorbed power state;As upstream discharge is random, it is impossible to
Accurately measure, therefore power station low voltage generator intelligent operation device measures water-retention water by cistern level sensor
When the real-time height of position and variation tendency, to negative-feedback regu- lation mechanism is introduced in electromotor guide vane opening real-time control, by right
When the change of current level measured value judges that upstream discharge increases, first with Δ x1 increments, guide vane opening is increased in right amount, then
By the rate of change for judging water level after the adjustment, the i.e. change of Δ H=H1-H are continued to monitor to water level, if raising speed on water level
Degree i.e. Δ H more than 0>0, then continue to increase guide vane opening with Δ x1 increments and continue observed stage, judge that height of water level changes, directly
Stability is in water level;In the same manner, when upstream discharge is reduced, Δ x2 is decrement, appropriate with Δ x2 decrements first
Electromotor guide vane opening is reduced, then by the judgement to SEA LEVEL VARIATION speed Δ H=H-H1 controlling whether persistently to reduce stator
Aperture, if drawdown rate of water level be 0, i.e. Δ H>0, then should continue to reduce guide vane opening with Δ x2 decrements and continue measurement
Water level, judges that height of water level changes, until water level is in stability.
In above-mentioned technical proposal, during adjustment electromotor guide vane opening, concrete operations include:
1), when, water level rises, it is to realize quick adjustment water level to equilibrium point, first, guide vane opening adjusting step Δ x1
Higher value is taken suitably, if the water level rate of climb is decreased obviously after adjustment, then during subsequent adjustment, should be by adjusting step Δ x1
Reduce, finely tune;
2), when water level decreasing, to prevent, water level decreasing is too fast to there is motive power deficiency situation, first by electromotor stator
Aperture decreasing amount adjustment step delta x2 takes higher value, allows water level in propradation, then again by less Δ x2 realizing fine setting;
3), electromotor guide vane opening adjustment final equilibrium point should be specified height of water level area, i.e. water level balance point, greatly
In warning line point and certain nargin is left, prevent from having little time to adjust guide vane opening during water level decreasing, water level is just rapid low
In marginal value region, therefore, should be according to the difference of current level and warning line point come with due regard to during adjusting every time
When the difference of the adjusting step of guide vane opening, i.e. current level and warning line is less, that is to say, that current level soon reaches
During warning line, it should first adjustment reduce guide vane opening so that cistern can water-retention, water level is controlled first in specified water
Position height area, then increase the adjusting step of guide vane opening in right amount so that current level is balanced.
In above-mentioned technical proposal, the Rule of judgment that the adjustment of electromotor stator is completed is that SEA LEVEL VARIATION speed Δ H is 0, in reality
In the processing procedure of border, Δ H can not possibly be accurate 0 value, therefore the Rule of judgment that this utility model completes to adjust is | Δ H |<ε,
Wherein, ε is a positive number;ε chose conference and reduced degree of regulation;Choose too small when can increase water level regulation and being close to equilibrium point
Fine setting number of times so that cause the damage of actuator because of regulation frequent to guide vane opening, therefore the selection of ε, need basis
Practical situation and it is actually needed to determine.
In above-mentioned technical proposal, multicomputer when power station multiple generator group generates electricity is adjusted, and needs to ensure water-retention pool water level
Balance and every unit balancing the load, therefore when water level rises, the minimum unit of preferential Load adjustment amount;Under water level
When drop, preferential Load adjustment amount highest unit, the loading of every unit are judged by guide vane opening, the load of unit
The more big then guide vane opening of amount is bigger;During multicomputer adjustment, need to judge the size of unit load amount, every unit connects
Enter the loading signal of other units;It is determined that the preferential unit for adjusting, it is identical with single fighter adjustment which adjusts process.

Low-tension unit overall-in-one control schema, in addition to it can realize the basic functions such as measurement, protection and the distant place control of low voltage generator, should
Device can also be by level sensor come sensed water level height, and then by the judgement to cistern current level adjusting automatically
Section guide vane opening, so as to reach to generated output optimizing regulation function:When monitoring that water level rises, device control increases
Guide vane opening, increases water yield so that water level maintains a new dynamic equilibrium point so as to lift generator prime power, increases
Electromotor water power;Device control when water level decreasing reduces guide vane opening, reduces water yield so that water level is tieed up
Hold in new dynamic equilibrium point, allow electromotor continuous service in power generation mode, keep the generated output in power station.The device can
Allow power station power adjustments to reach automatization, and the generated output of electromotor can be optimized in certain degree, allow power station

The intelligent operation method of above-mentioned power station low voltage generator intelligent operation device is:Power station low voltage generator intelligence
Running gear by level sensor sensed water level height, by processor MCU by the judgement to cistern current level from
It is dynamic to adjust power station low voltage generator guide vane opening, to generated output optimizing regulation:When monitoring that water level rises, water power
Low voltage generator intelligent operation device of standing control increases electromotor guide vane opening, increases water yield so that water level is maintained to one
New dynamic equilibrium point, lifts generator prime power, increases electromotor water power;Power station when water level decreasing
The control of low voltage generator intelligent operation device reduces guide vane opening, reduces water yield so that water level maintains new dynamic equilibrium
Point, allows electromotor continuous service in power generation mode, keeps the generated output in power station, make power station low voltage generator generated output
Automatization is adjusted, and optimizes the generated output of electromotor;Concrete grammar is:Power station reaches balance in displacement and inflow
When, guide vane opening x, the Water level trend balance height of cistern is H;When a certain moment upstream discharge increases, intelligent operation
Device monitors that within the unit interval real time water level H1 of cistern is in propradation, i.e. H1-H>0, then it represents that can increase
Leaf divergence is led, increases the generated output of electromotor;Increase guide vane opening x1 after electromotor guide vane opening is adjusted, it is necessary to full
Foot can keep the dynamic equilibrium of water-retention pool water level, i.e. cistern inflow and water yield is equal, and so just can guarantee that will not
There is water level decreasing because guide vane opening adjustment is excessive;In the same manner, when a certain moment upstream discharge is reduced, intelligent operation dress
Put and monitor that the real time water level H1 of cistern is in decline state, i.e. H1-H within the unit interval<0, it is to keep electromotor to continue
It is operated in generating state, it is desirable to reduce electromotor leads leaf divergence, on the one hand guide vane opening x2 after adjustment needs the satisfaction can
Water level trend balance is kept, is on the other hand also needed to meet water level balance point and is not less than warning line point, the water level point is critical
Water level point, if being consistently less than this water level point, generator prime power deficiency is likely to occur absorbed power state;Due to upstream current
Amount is random, it is impossible to accurately measured, therefore power station low voltage generator intelligent operation device is by cistern level sensor
When device is to measure the real-time height of water-retention pool water level with variation tendency, to introducing negative feedback in electromotor guide vane opening real-time control
Regulatory mechanism, it is when judging that upstream discharge increases by the change to current level measured value, suitable with Δ x1 increments first
Amount increases guide vane opening, then by the rate of change for judging water level after the adjustment, the i.e. change of Δ H=H1-H are continued to monitor to water level
Change, if the water level rate of climb is more than 0, i.e. Δ H>0, then continue to increase guide vane opening with Δ x1 increments and continue observed stage,
Judge that height of water level changes, until water level is in stability;In the same manner, when upstream discharge is reduced, Δ x2 is decrement,
Reduce electromotor guide vane opening in right amount by decrement of Δ x2 first, then by the judgement to SEA LEVEL VARIATION speed Δ H=H-H1 come
Control whether persistently to reduce and lead leaf divergence, if drawdown rate of water level is not 0, i.e. Δ H>0, then should continue to subtract with Δ x2 decrements
Few guide vane opening simultaneously continues to measure water level, judges that height of water level changes, until water level is in stability.
During adjustment electromotor guide vane opening, concrete operations include:
1) when, water level rises, it is to realize the quick water level that adjusts to equilibrium point, guide vane opening adjusting step Δ x1 first is fitted
When higher value is taken, if the water level rate of climb is decreased obviously after adjustment, then during subsequent adjustment, adjusting step Δ x1 should be subtracted
It is few, finely tune;
2), when water level decreasing, to prevent, water level decreasing is too fast to there is motive power deficiency situation, first by electromotor stator
Aperture decreasing amount adjustment step delta x2 takes higher value, allows water level in propradation, then again by less decrement Δ x2 come real
Now finely tune;
3), electromotor guide vane opening adjustment final equilibrium point should be specified height of water level area, i.e. water level balance point, greatly
In warning line point and certain nargin is left, prevent from having little time to adjust guide vane opening during water level decreasing, water level is just rapid low
In marginal value region, therefore, should be according to the difference of current level and warning line point come with due regard to during adjusting every time
When the difference of the adjusting step of guide vane opening, i.e. current level and warning line is less, that is to say, that current level soon reaches
During warning line, it should first adjustment reduce guide vane opening so that cistern can water-retention, water level is controlled first in specified water
Position height area, then increase the adjusting step of guide vane opening in right amount so that current level is balanced.
The Rule of judgment that the adjustment of electromotor stator is completed is that SEA LEVEL VARIATION speed Δ H is 0, in actual process, Δ H
Can not possibly be accurate 0 value, therefore the Rule of judgment for adjusting is | Δ H |<ε, wherein, ε is a positive number;ε chose conference drop
High adjustment precision;Choose the too small fine setting number of times that can increase when water level regulation is close to equilibrium point so that because to guide vane opening frequency
Numerous regulation and cause the damage of actuator, therefore the selection of ε needs according to practical situation and is actually needed to determine;Water power
Multicomputer when multiple generator group of standing generates electricity is adjusted, and needs the balancing the load of the balance and every unit of guarantee water-retention pool water level,
Therefore when water level rises, the minimum unit of preferential Load adjustment amount;In water level decreasing, preferential Load adjustment amount highest
Unit, the loading of every unit judge that by guide vane opening the more big then guide vane opening of loading of unit is bigger;Many
During unit adjustment, need to judge the size of unit load amount, every unit accesses the loading signal of other units;It is determined that
The preferential unit for adjusting, it is identical with single fighter adjustment which adjusts process.
