Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
Nuclear power plant system composition is complicated, and systemic-function is varied, and considerable system is all relevant to nuclear power plant overall operation (start, shutdown).In reactor shutdown process, to cooperatively interacted complexity and the requirement accurately of the sequence of operation of nuclear power plant's each several part, operation opportunity and operator.Digitizing overall operation Presentation Function analytical approach of the present invention, from operation angle, analyzes unit under each stan dard running model steady-state operating condition, and in the process of neighboring modes conversion, performs overall code information needed, and the deployment scenarios of information.
As shown in Figure 1, digitizing overall operation Presentation Function specific analytical method is as follows:
(1) nuclear power plant start and stop transport process in, the time needed for the implementation of overall code is longer, and except some situation, the process of transient state is also slower.Consider this execution feature of overall code just, and the operating file system of syncaryon group of motors, the principle 1.1 that the present invention establishes " for each stan dard running model of unit, all needing to arrange corresponding overall operation Presentation Function, to monitor the set state under this pattern ").
In addition, in some stage, when unit carries out patten transformation, unit will be in fast-changing transient process.For carrying out the status surveillance of unit targetedly, the principle 1.2 that the present invention establishes " to some fast transients, need arrange corresponding overall operation Presentation Function, to monitor the set state in transient process ").
(2) according to principle described in step (1), whole startup and the stoppage in transit process of unit is analyzed.The inventory of the overall operation Presentation Function of required design can be obtained, and the overall operation stage that each overall operation Presentation Function is corresponding.
(3) in power plant's overall operation process, can relate to a large amount of systems in power plant, each system comprises again a large amount of monitor messages.But for ease of running, reduce the blocked operation number of times of screen, each overall operation Presentation Function should be able to show on one screen.Again because screen resolution is limited, the quantity of information contained by a width screen can not be infinitely great, therefore needs the information determining screen shows to carry out limiting and screening.
The screening principle that the present invention establishes is:
A) " system information needed for the mandatory requirement of " technical manual "/" overall code " is met for making the running status of power plant " or " information for needed for the crucial transient process of reflection power plant " should directly be included in overall operation Presentation Function.
B) important for some operation, but do not belong to system information a), can monitor in detail in the system Presentation Function of correspondence, only need to retain profile information in overall operation Presentation Function.
C) when the information in a) is too much, can simplify according to " importance of information " and " frequency that information monitoring requires ", concrete mode, with reference to b), namely monitors in detail in the system Presentation Function of correspondence, only needs to retain profile information in overall operation Presentation Function.
(4) according to the principle in step (3), whole startup and the stoppage in transit process of unit is analyzed.The monitor message inventory of overall operation Presentation Function requirement can be obtained.
(5) because the information on overall operation Presentation Function is more, kind is complicated, the arrangement principle of information in this function need be determined, to ensure that operator can find required information fast.After the operating characteristic considering operator and operation custom, the present invention determines arrangement principle: " kind according to information is divided into groups to the information in overall operation Presentation Function; and group internal information is further subdivided into different subgroups according to the difference of said system, and the information in subgroup and subgroup is arranged according to the flowing water order of item.Further, each overall operation Presentation Function uses unified layout template." mentioned above principle one typical case masterplate sample as shown in Figure 2.
(6) according to the principle in step (5), cloth postpone is carried out to the monitor message inventory that the overall operation Presentation Function in step (4) requires, the design of overall operation Presentation Function can be completed.

2, the information inventory determined in overall operation Presentation Function is analyzed
After detailed analysis is carried out to the whole service stage, obtain all information inventories needed for this stage running.In all inventories, the amount that the quantity of information comprised can comprise much larger than a width screen.Application technical solution of the present invention step (3) is simplified the content in inventory and optimizes:
Principle is example a): the aperture of atmospheric dump valve and feedwater switch the content that in " overall operation codes " such as permission signals, directly requirement monitors to be needed directly to monitor.
Principle b) example: whole unloading phase, operator all needs the temperature and pressure change paying close attention to reactor, but, consider that the emphasis in this stage not monitors this information, therefore, carried out simplifying display to above-mentioned information: increase the link that can be connected to this information in overall operation Presentation Function, instead of direct by this information displaying in overall operation Presentation Function.
Principle c) example: rod withdrawal operation need monitor the excellent position of each root control rod; But because onscreen information is containing quantitative limitation, the detailed supervision of this part can only be checked to control rod control system Presentation Function, and overall operation Presentation Function then only retains overview monitor message.
Through above-mentioned optimization, all information inventories are converted into " the information inventory in overall operation Presentation Function ".
3, the preferred arrangement of information displaying
Utilize the principle of technical solution of the present invention step (5), according to unified, " the information inventory in overall operation Presentation Function " is arranged that cloth postpone is carried out in the requirement of template, the overall operation synthesis display function in " from hot shutdown to low power run " stage can be applied to.
In the present embodiment, complete cloth postpone according to template, completing the information category grouping in overall operation Presentation Function.In concrete placement process, as shown in " battery limits ", equipment wherein divides again in order to different subgroups according to the difference of said system, and each subgroup is gathered with dark-background.Information in subgroup and subgroup is arranged according to the flowing water order of item.The overall operation that this embodiment obtains controls Presentation Function interface as shown in Figure 3.
