Abstract
Disclosed is an automatic fuel control method under fuel oil (gas) unit coordination. According to the automatic fuel control method under fuel oil (gas) unit coordination, in a coordination mode, operating personnel sets a target load, feeding or withdrawing from fuel is judged automatically through load deviation after rate increasing or decreasing, a steam engine adjusts the load automatically, and a boiler controls oil flow rate automatically, so that operation frequency of the operating personnel is reduced.
Description
Technical field
Fuel oil of the present invention（Gas）Oil gun autocontrol method under unit cooperative mode, is related to coordinate control field, is applied to
The fuel increase and decrease control of oil fired and gas fired unit.
Background technology
Current coordinated control system is mainly the Control PID control of boiler side fuel quantity increase and decrease and meets boiler hot release and machine
The matching of group energy requirement, steam turbine side is then matching realizing coordination control by PID control actual load and target load,
And the oil gun of the burner quantity that either natural gas air gun puts into still voluntarily is judged to increase and decrease or reduce by operating personnel, so
Automatic Control can not be referred to as, and be belonging to a kind of semiautomatic control.
The content of the invention
Operating frequency in order to reduce operating personnel of the invention, reduces the level difference due to operating personnel and system is produced
Deviation under the speed of the different ascending, descending loads given birth to different impacts and design according to actual load and target load passes through load
Deviation automatic decision puts into or exits fuel, and steam turbine automatically adjusts load, and Automatic Control of Boiler oil flow reduces operations staff
Operating frequency.Need to increase oil gun during load is increased（Air gun）, put into angle oil gun（Air gun）Instruct after sending in oil
Rifle（Air gun）Group on startup between timing terminate rear system be not detected by fire inspection signal be considered as startup failure then can directly to setting
Fixed next angle sends input instruction；And only need to fuel tap during load down（Air valve）Closing is not in unsuccessfully feelings
Condition, Gu not considering unsuccessfully to redirect situation, directly exits oil gun according to the order of setting（Air gun）.

Present example provides fuel oil（Gas）Fuel autocontrol method, is applied to fuel oil under unit cooperative mode（Gas）Machine
Group coordinated control system also can be exited separately as a kind of increasing and decreasing load fuel input and automatically controlled.Layout of boiler be from lower and
Upper distribution sequence has 8 layers for A, B, C, D, E, F, G, H, wherein automatically controlling logic relates only to totally 4 layers of E, F, G, H, increases negative
From bottom to top E, F, G, H layer successively increases fuel when lotus needs to increase fuel, when load shedding needs to reduce fuel from top to bottom H,
G, F, E layer successively reduces fuel, and each layer has 4 burning angles, and each angle has 3 kinds of fuel available, and a certain layer needs burning
Which kind of fuel requirement operating personnel is selected manually, and logic carries out judgement goes which kind of fuel voluntarily controlled, the throwing at 4 burning angles
Enter order to put into one by one as needed for 1 → 3 → 2 → 4 jiaos, exit order and exit one by one as needed for 4 → 2 → 3 → 1 jiao.
Increase Fuel Process：After unit commitment is coordinated to control, after operating personnel's input fuel automatic switching button, if
A fixed desired value higher than present load, logic carries out judgement to be needed to increase load, judges whether E1 angles have been put into, if
Oil is not put into（Gas）Logical order automatically engages the selected fuel of E1 after press strip part meets, the oil if E1 angles have been put into
（Gas）Logic sends instruction and automatically engages the selected fuel of E3 after press strip part satisfaction, or E1 angles fuel is in the input of setting
It is interior not put into successful oil（Gas）Logic sends instruction and automatically engages the selected fuel of E3 after press strip part satisfaction；E1 puts into
Afterwards, now logic judgment remains a need for increasing load, judges whether E3 angles have been put into, if the time for not being dropped in setting arrives
Up to rear oil（Gas）Logical order automatically engages the selected fuel of E3 after press strip part meets, the oil if E3 angles have been put into（Gas）
Logic sends instruction and automatically engages the selected fuel of E2 after press strip part satisfaction, or E3 angles fuel is in the making time of setting
Successful oil is not put into（Gas）Logic sends instruction and automatically engages the selected fuel of E2 after press strip part satisfaction；After E3 inputs, this
When logic judgment remain a need for increase load, judge whether E2 angles have been put into, if be not dropped in the time of setting arrival after
Oil（Gas）Logical order automatically engages the selected fuel of E2 after press strip part meets, the oil if E2 angles have been put into（Gas）Press strip
Logic sends instruction and automatically engages the selected fuel of E4 after part satisfaction, or E2 angles fuel does not have in the making time of setting
Put into successfully oil（Gas）Logic sends instruction and automatically engages the selected fuel of E4 after press strip part satisfaction；After E4 inputs, now patrol
Collect judgement to remain a need for increasing load, judge whether E4 angles have been put into, if not being dropped in oil after the arrival of the time of setting
（Gas）Logical order automatically engages the selected fuel of E4 after press strip part meets, the oil if E4 angles have been put into（Gas）Press strip part
Logic sends instruction and automatically engages the selected fuel of F1, or the no throwing in the making time of setting of E4 angles fuel after satisfaction
Enter successfully oil（Gas）Logic sends instruction and automatically engages the selected fuel of F1 after press strip part satisfaction；According to sequence described above according to machine
Group is to the increasing demand of load successively according to E, F, G, H layer, 1 → 3 → 2 → 4 jiaos of order input fuel, until no longer needing to increase
Plus.
Reduce load process：After unit commitment is coordinated to control, after operating personnel's input fuel automatic switching button, if
A fixed desired value less than present load, logic carries out judgement to be needed to reduce load, judges whether H4 angles have logged out, if
Oil is not exited（Gas）Logical order automatically exits from the selected fuel of H4 after press strip part meets, the oil if H4 angles have logged out
（Gas）Logic sends instruction and automatically exits from the selected fuel of H2 after press strip part satisfaction；After H4 is exited, now logic judgment is still needed to
Load is reduced, judges whether H2 angles have logged out, if not exiting the oil after the time of setting reaches（Gas）Press strip part is expired
Logical order automatically exits from the selected fuel of H2 after foot, the oil if H2 angles have logged out（Gas）Logic is sent out after press strip part meets
Go out instruction and automatically exit from the selected fuel of H3；After H2 is exited, now logic judgment remains a need for reducing load, whether judges H3 angles
Have logged out, if not exiting the oil after the time of setting reaches（Gas）Logical order automatically exits from H3 institutes after press strip part meets
The fuel of selection, the oil if H3 angles have logged out（Gas）Logic sends instruction to automatically exit from H1 selected after press strip part meets
Fuel；After H3 is exited, now logic judgment remains a need for reducing load, judges whether H1 angles have logged out, if do not exited
Oil after the time arrival of setting（Gas）Logical order automatically exits from the selected fuel of H1 after press strip part meets；H layers are judged afterwards
Whether all exit, if H layers have all been exited after the time of setting reaches, judge whether G4 has dropped out, if do not had
Exit oil（Gas）Logic sends instruction and automatically exits from the selected fuel of G4 after press strip part satisfaction, if G4 angles have logged out set
Oil after fixed time arrival（Gas）Logic sends instruction and automatically exits from the selected fuel of G2 after press strip part satisfaction；It is suitable according to more than
Sequence according to unit to the increasing demand of load successively according to H, G, F, E layer, 4 → 2 → 3 → 1 jiao of order exits fuel, until no longer
Need to reduce.
