Abstract
Invention describes during a kind of fired power generating unit automatic start-stop control system is run the method increasing and decreasing breakpoint, the method comprises the steps: (1), increase the input/exit function of function group; (2) input/exit function of function subgroup, is increased; (3) selection function of stand-by equipment each other, is increased.The method, on operation screen, adds and drops into/exit to each function group, function subgroup, each other stand-by equipment in fired power generating unit automatic start-stop control system or select button; Make operating personnel can increase and decrease breakpoint in fired power generating unit automatic start-stop control system operational process, interim input or exit any function group, function subgroup in APS, or select an equipment for subsequent use each other, APS is run to be needed automatically to stop when intervening, wait for that operating personnel check, confirm, substantially increase adaptability and the operability of APS.
Description
Technical field
The invention belongs to fired power generating unit automatic control technology field, be specifically related to a kind of method increasing and decreasing breakpoint during fired power generating unit automatic start-stop control system is run.
Background technology
(abbreviation of English " automatic plant startup and shutdown control system ", Chinese translation is " fired power generating unit automatic start-stop control system " to APS.) adopt hierarchical design, be divided into some function groups by the start-up course of fired power generating unit and stopping process, be divided into again some function subgroups under each function group, function subgroup directly controls field apparatus.Only need operating personnel to implement simple inspection, confirmation, APS can complete the whole start-up course of fired power generating unit and stopping process automatically by pre-set programs.Current APS reaches its maturity, becomes the technology of newly-built Large-scale fire-electricity unit widespread use gradually.
But APS known both at home and abroad at present, be designed with fixing breakpoint (breakpoint) all in a program in advance, namely only have when APS runs to these fixing breakpoints, the inspection of the wait operating personnel that just can stop, confirmation.Along with the continuous expansion of Large-scale fire-electricity unit capacity, being on the increase and the increasingly complex of process system of subsidiary engine equipment, in fired power generating unit shutdown process subsidiary engine equipment break down temporarily or the situation of process system temporary demand manual intervention more and more common.Therefore, preset the mode of fixing breakpoint in known APS program, operating personnel can not be made in APS runs to fulfil manual intervention in time, thus cause operating personnel to be reluctant even to cast away use APS.
Summary of the invention
The technical problem to be solved in the present invention is, for the defect that prior art exists, increases and decreases the method for breakpoint in providing a kind of fired power generating unit automatic start-stop control system to run.Use the method, can make operating personnel in APS operational process, according to the temporary demand of subsidiary engine equipment and process system, interim increase or minimizing breakpoint.Like this, by automatic pause when APS runs to the step needing to intervene, the inspection of operating personnel and confirmation is waited for, so as to improving adaptability and the operability of APS.
Technical scheme of the present invention is, the above-mentioned fired power generating unit automatic start-stop control system provided increases and decreases breakpoint method in running comprises the steps:
(1) input/exit function of function group, is increased: open the fired power generating unit automatic start-stop control system and APS waiting to increase and decrease breakpoint.According to the APS using method that this APS manufacturer provides, total operation screen of APS increases " function group is thrown and moved back " link.Click this link, make display screen show input state or the exit status of APS each function group button, the default conditions of this button are input state; The APS using method continuing to use described APS manufacturer to provide carries out steering logic programming to this APS: in the control enabled condition of each function group of described APS, increase this function group " drop into " condition, namely setting represents button that function group drops into when not being pressed, and this function group will not allow to perform;
(2) input/exit function of function subgroup, is increased: continue the APS using method using above-mentioned APS manufacturer to provide, total operation screen of APS or the operation screen of each function group increase " function subgroup is thrown and moved back " link, click this link, make display screen show input state or the exit status of each function subgroup button and this button under each function group, the default conditions of this button are input state; The APS using method using APS manufacturer to provide proceeds steering logic programming to this APS: in the control enabled condition of each function subgroup, increase this function subgroup " drop into " condition, namely setting represents button that function subgroup drops into when not being pressed, and this function subgroup will not allow to perform;
(3) selection function of stand-by equipment each other, is increased: continue the APS using method using above-mentioned APS manufacturer to provide, the operation screen of total operation screen of APS or the operation screen of each function group or each function subgroup increases " equipment choice " link, click this link, display screen is made to show the selection mode of the button of stand-by equipment each other under each function subgroup, the button of such as display " selection oil pump A ", " selecting oil pump B " and selection mode thereof, wherein oil pump A, oil pump B are for subsequent use each other, only need start wherein one in normal operation; The APS using method that theres is provided of APS manufacturer is used to carry out steering logic programming to this APS: in the control enabled condition of each stand-by equipment each other, to increase this equipment " select " condition, namely, when the button that setting represents equipment choice is not pressed, the steering order of this equipment will not allow to perform.
Technological core of the present invention is: use the method that APS manufacturer provides, on operation screen, each function group in fired power generating unit automatic start-stop control system, function subgroup, each other stand-by equipment are added throwing and moved back or select button, and throws the state display moved back and select; And the method using APS manufacturer to provide carries out steering logic programming, in the control enabled condition of each function group, function subgroup, each other stand-by equipment, increase " dropping into " or " selecting " condition of this function group, function subgroup, each other stand-by equipment.
The invention has the beneficial effects as follows: use this method, operating personnel can increase and decrease breakpoint in fired power generating unit automatic start-stop control system operational process, can according to the temporary demand of subsidiary engine equipment and process system, interim increase or minimizing breakpoint.Namely drop into temporarily or exit any function group, function subgroup in APS, or interim select any equipment for subsequent use each other, suspend when making APS run to the step needing to intervene, wait for that operating personnel check, confirm, substantially increase adaptability and the operability of APS.
