Description
Technical field
The present invention relates to steam turbine automatic control technology fields, and in particular to a kind of domestic steam turbine self-starting control
Method processed.
Background technology
Automatic steam turbine control (Automation Turbine Control, ATC) technology refers to that steam turbine can be realized
From hanging lock to raising speed to rated speed or take the whole-process automatic control process of unit initial load.It is steamed in domestic super (super-) critical
In steam turbine control system, mating control system is allowed in addition to Shanghai steam turbine plant Co., Ltd uses for reference Siemens's technology
Outside with self-starting function, the control system of other steam turbine plants does not have this function；Or only devise the Xiang Gong
Can, but due to being limited by China's fired power generating unit early period automatization level development degree and external ATC technological assimilation is absorbed
It is insufficient so that the ATC technologies introduced can not be applied in practice.
APS (Automatic Power Plant Starup and Shut-down System, APS) is to flare up in recent years
One important directions of motor group development can improve the correctness and normalization of fired power generating unit shutdown process, mitigate operation
The labor intensity of personnel shortens the Unit Commitment time, is to improve the horizontal effective approach of unit automation.Wherein, ATC is
An important component in APS.In a sense, whether the steam turbine control system that unit is configured has ATC
Function is the key factor that can APS realize.
Invention content
The technical problem to be solved by the present invention is in view of the defects existing in the prior art, provide a kind of steam turbine and open certainly
Dynamic control strategy, this method can realize that steam turbine is straight from automatic extension lock, operation, friction inspection, medium-speed warming, progress Vavle switching
To the whole-process automatic control function of rising to rated speed, reduce the operation of operations staff, improve the automatization level of unit.
A kind of steam turbine booting-self controller method, includes the following steps：
Step 1：According to each component signal of steam turbine and ATC working method signals, perform and hang lock signal；
Step 2：When steam turbine is completed to hang lock, and turning motor has been started up or steam turbine rotating speed is more than minimum set
During value, steam turbine run signal is performed；
Step 3：After steam turbine has been run, it is 500r/min signals to perform setting rotating speed of target；
Step 4：According to " friction is needed to check " button signal, " 500r/min frictions check " instruction is performed；
Step 5：When " need friction check " button do not put into and steam turbine rotating speed be located at 490r/min-510r/min it
Between when, perform setting rotating speed of target be 2000r/min signals, enter step 6；
When " friction is needed to check " button is put into and steam turbine rotating speed is between 490r/min-510r/min, hold
Row steam turbine trip signal, and return to step 1；
Step 6：2000r/min medium-speed warmings are performed according to rotating speed of target and given rotating speed；
Given rotating speed is the rotating speed of setting, and given rotating speed is close to rotating speed of target according to the steam turbine raising speed rate of setting.
Step 7：Time and steam turbine rotating speed are performed according to warming-up, it is 2900r/min signals to perform setting rotating speed of target；
Step 8：When given rotating speed is equal to 2900r/min, Vavle switching instruction is performed；
Step 9：After the completion of Vavle switching, it is 3000r/min signals to perform setting rotating speed of target；
Step 10：" ATC completes to check " instruction is performed, until steam turbine actual speed is in 2995r/min~3005r/
Between min.
Preferably, it is performed in the step 1 before hanging lock signal, each component signal of steam turbine and ATC modes at least should
Meet following condition：
1. steam turbine has tripped；2. lubricating oil system is normal；3. EH oil systems are normal；4. all valves are fully closed；5. own
Drain valve is fully closed；6. big alarm without acceptance of persons；7. without the big alarm of the vaporium inside and outside wall metal temperature difference；8. without golden above and below High-and-medium Pressure Outer Casing
Belong to the big alarm of the temperature difference；9. low pressure (LP) cylinder exhaust temperature is normal；10. ATC working method signal enablings.
Preferably, manual confirmation is carried out to ATC working methods by hand push button whether choosing.
When selecting " ATC modes ", steam turbine control system uses self-starting mode；When " ATC modes " be not selected,
Steam turbine control mode is still ordinary operation mode.
In order to increase the safety and reliability of steam turbine self-starting control system, there is provided " starting ATC " manual confirmations
Button.When more than entry condition all meets, " starting ATC " button is clicked, steam turbine control system will perform automatically " to be hung
Lock " instructs.
Advantageous effect
The present invention provides a kind of domestic steam turbine booting-self controller method, basic step includes：1) lock is hung automatically；2)
Automatic running；3) rotating speed of target 500r/min is put automatically；4) 500r/min frictions check；5) rotating speed of target 2000r/ is put automatically
min；6) 2000r/min medium-speed warmings；7) rotating speed of target 2900r/min is put automatically；8) Vavle switching is carried out automatically；9) mesh is put automatically
Mark rotating speed 3000r/min；10) ATC completes to check.Entire control process is whole-course automation, easy to use；
Compared to the prior art, tool has the advantage that：
1. the present invention can realize domestic steam turbine from automatic lock, operation, friction inspection, the medium-speed warming hung up to rising
To the whole-process automatic control of rated speed, without manual intervention, the labor intensity of operations staff is alleviated；2. it is opened certainly in steam turbine
During dynamic, ATC voluntarily judge (whether the cold-hot condition of such as steam turbine was critical turn by the state to steam turbine
Fast region etc.), the warm-up period and raising speed rate of steam turbine can be set automatically, life consumption and startup in steam turbine
Reach between time automatically preferentially；3. can ATC be realized with most important APS as the important component in APS
Effect.Therefore, the present invention has good progradation for the practical application of steam turbine automation control and APS.
In the present invention, steam turbine rotating speed of target is gradually set to maximum speed, such as put rotating speed of target 500r/min,
Rotating speed of target 2000r/min is put, rotating speed of target 2900r/min is put, puts rotating speed of target 3000r/min etc., is not similar existing
Steam turbine ATC system in set just put target for the first time as maximum speed, the wind in steam turbine start-up course can be reduced in this way
It is dangerous；In addition, " pause ATC " button also set up in the ATC system of the present invention, when physical condition is unsatisfactory for or undesirable, need
It when wanting ATC program stoppeds, can click on, ATC will keep current step sequence no longer to carry out；Restore ATC when condition meets needs
It during program, then clicks on, ATC step sequences will perform automatically.
ATC reduces the manual operation time due to not needing to manual operation in the present invention.Warm-up period is not included such as
Inside, the ATC start-up courses in the present invention are about 10 minutes, and the more conventional manually-operated time is short.
A plurality of ATC is provided with according to steam turbine feature in the present invention and starts enabled condition, it is all full when starting enabled condition
It just can perform ATC step sequences when sufficient, therefore have preferable protective effect in itself for steam turbine.In ATC start-up courses, steam turbine
Bias, bearing temperature, absolute expansion, axis shake, the important parameters such as axial displacement can reach good index, to a certain extent
Extend the service life of steam turbine.
