Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Various embodiment of the present invention provides the control method of a kind of nuclear power plant operation.At first will move general assignment and be decomposed into availability task (controlled generating) and security task (preventing radioactivity release), the operation general assignment is that the main target (realizing power plant safety and effectively operation under its all operations and accident conditions) according to nuclear power plant is determined.Then availability task and security task are decomposed into respectively at least two subtasks, and judge whether each subtask meets default termination rules, if do not meet, do not continue to decompose this subtask until meet termination rules (being that corresponding task can not be decomposed again).Wherein, termination rules comprises following at least one: this subtask has nothing to do with main control room or is no longer control task; Individual task, parameter and/or controller can be controlled in this subtask; This subtask no longer comprises subtask.Next determine that for the subtasks at different levels that meet termination rules power plant moves required basic task information flow and task processing requirements.
Then, the basic task information flow is carried out to task analysis, determine various control informations and the execution information relevant to task, and carry out the task distribution according to the result of task analysis.Wherein task analysis at least comprises with the next item down: identical subtask is merged; The subtask of realizing correlation function is combined as to a kind of combined task.Next judge task distributes whether meet default allocation criteria, if do not meet this task of redistributing, until meet.Wherein, allocation criteria comprises following at least one: determine the allocation criteria which kind of assigns the task to and carry out terminal according to task characteristic; Determine and take the remote allocation criteria of still controlling on the spot of manually controlling according to objective condition; Carry out the allocation criteria of task distribution according to the safety requirements under accident conditions; Carry out the allocation criteria of task distribution according to the information block based on function.
Fig. 1 is the process flow diagram of the control method that nuclear power plant moves according to an embodiment of the invention.In the present embodiment, at first the control method of nuclear power plant's operation performs step S1 after starting.In step S1, the decomposition of executing the task, generate at least two subtasks.Because the present invention carries out task analysis and distribution mainly for the pulpit of nuclear power station, therefore can at first the general assignment of nuclear power station operation (being that An full ﹑ effectively generates electricity and the protection public avoids radiation hazard) be decomposed into to availability task (controlled generating) and security task (preventing radioactivity release).In decomposable process, can also determine the whole power plant task relevant with main control room for each subtask, only to controlling inter-related task, decomposed.
In step S2, judge whether each subtask meets default termination rules.According to the Standard andRegulation of nuclear power station, the termination rules of the Task-decomposing that the present invention is default comprises following at least one:
A) task is irrelevant with main control room, and for example control and complete on the spot, or this task is no longer a control task, but such as the tasks such as maintenance to equipment;
B) reached the degree that can control individual feature, parameter, controller;
C) this task no longer comprises subtask, such as this task, is simple mechanical action etc.
But the present invention is not limited to this, and can comprise the termination rules of any appropriate, as long as it is complete, independently that this termination rules makes the task of the required bottom reached of Task-decomposing, or can realize, and important hierarchical structure is clear and definite getting final product.
If there is the subtask that does not meet termination rules, S1 is continued respectively to perform step in the subtask that these is not met to termination rules.The rest may be inferred, until all subtasks all meet termination rules, and until the task of the bottom is complete and independently, or can realize, and important hierarchical structure is clear and definite, meets this standard and just can stop decomposing.
If all subtasks all meet termination rules, perform step S3.In step S3, determine according to subtasks at different levels basic task information flow and the task processing requirements that operation is required, for example set up system task model tree or other topological structure, mean subtasks at different levels and mutual relationship thereof.
In step S4, the basic task information flow is carried out to task analysis, comprise and determine various control informations and the execution information relevant to task.Wherein, task analysis can comprise following at least one, and comprises the analysis sequence of any appropriate:
A) determine the back-up system relevant with Given task, comprise process system, power supply, source of the gas etc.;
B) analyze as completing Given task, need the parameter that monitors and/or monitor which means power plant's state, such as: temperature, pressure, valve location etc.;
C) if Given task can not correctly be carried out, there is which other task to substitute;
D) operation that completes this task is automatically completed or manually completed by operator by machine;
E), if automatically control, need to carry out which backup manual and control;
F) no matter automatically still manually, operator will exercise supervision to some parameter, and which these parameters are, where are placed in;
G) if which equipment manual operation (backup manual that comprises automatic control is controlled) needs, where be placed in, in which kind of state just can finish the work;
H), if operation steps needs operator to carry out the senior thought processing, need to decide control action how to carry out by which parameter;
I) identical subtask is merged;
J) subtask that will realize correlation function is combined as a kind of combined task.
Whether, when task analysis is carried out in each subtask, can also differentiate and determine that whether this task is relevant to pulpit, be control task, in order to carry out subsequent allocations.
In step S5, according to the result of above-mentioned task analysis, carry out the task distribution.Task is divided timing, need to consider respectively the ability of operator and blind controller system.The task of for example, distributing to operator can be divided into three classes: carry out control task, to the supervision of automatic system and carry out the senior thought processing.According to factors such as the accuracy of the burden weight of this three generic task, requirement, response times, in the scope that does not exceed operator's ability, reasonably distributed.Again for example, while considering the processing power of blind controller system, the functional requirement that at first will stipulate system and equipment, then according to the requirement of operation task regulation man-machine interface, finally determine all technical, as the quantity of system and equipment, response time, degree of accuracy, Human Engineering requirement etc.
In step S6, judge whether above-mentioned task distribution meets default allocation criteria.Default allocation criteria can comprise following at least one:
Criterion 1: according to the characteristic of task, assign the task to operator or the criterion of machine in Table 1.
The task allocation criteria of table 1 operator and machine
1) operator's ability
In the nuclear power station design, the task of operator's burden comprises following three kinds: manually carry out a control task; The supervision automatic system is carried out control task; Carry out the senior thought processing.
2) processing power of instrument control system
Nuclear power station protection and controlling of task are mainly completed by the instrument control system, and this just requires to distribute to the control task (having considered the interaction with operator) of machine and processing (information and control) ability of instrument control system adapts.In the instrument control system, need to consider automatically control and manually control, its processing power comprises quantity, response time and the accuracy requirement for system or equipment, and the requirement of Human Engineering standard and Human Engineering standard are determined man machine interface's requirement to each base part.
Criterion 2: according to objective condition, take the remote manually task allocation criteria that control is still controlled on the spot in Table 2.
The remote task allocation criteria with manually controlling on the spot of table 2
Table 2 is only one embodiment of the present of invention, wherein only enumerated the part situation, but the present invention is not limited to this, and can comprise that any appropriate ground judgement takes the remote standard of manually controlling or controlling on the spot, as long as follow following general principle: requiring summary responses and obvious consequence being arranged of task is by manually having controlled at a distance.
Criterion 3: the safety requirements under accident conditions comprises the explanation of emergency operation rules.
Another source of task allocation criteria is the safety requirements under accident conditions.Criterion 3 is defined as follows: the quick operation response task that accident conditions lower-pilot person has little time to be intervened must be distributed to machine, for important safe operation, except the task that automatic control is arranged, also must be provided with the manual control task of redundancy, supplementing while in order to conduct, automatically controlling inefficacy.
Criterion 4: information block.
According to controlling-show comprehensive principle, the various information that are applicable to operator are divided into groups by function, be divided into one group taking each to operate required information, so that for operator provides an integrated information system in its limit of power, rather than by the information source grouping.
If exist the task of not meeting allocation criteria to distribute, return to step S5 and redistribute the task that these do not meet allocation criteria, until distributing, all tasks all meet allocation criteria.
All meet allocation criteria if all tasks are distributed, the task assigning process finishes so.The relevant execution terminal of main control room in can the control task executive system carried out respectively the task of distribution.For example, the operator and the instrument control equipment that are assigned with task will be carried out task separately as requested, thereby reach the operation general objective.
Fig. 2 is the process flow diagram of task analysis algorithm according to an embodiment of the invention.In the present embodiment, the task analysis algorithm starts from step 201.
In step 201, the operation general assignment of nuclear power station is decomposed into to availability task (controlled generating) and security task (preventing from discharging radioactivity to environment).
Specifically, can carry out detailed Task-decomposing according to following task to pulpit:
A) availability task
1) making power plant reach the Power operation state, is for example 15% rated power from the cold shut operating mode to the band minimum load;
2) control the core steam supply under various normal operating modes, for example firm power operation---be stabilized in a certain power level operation in 15%～100% rated power scope, load-following operation---from 15% rated power load up to 100% rated power, from 100% rated power load down to 15% rated power;
3) steam-energy is converted to electric energy;
4) cold-refueling, comprise from 15% rated power to cold shut and the work in every that reloads;
B) security task
Safe task is to prevent that radioactivity release is in environment, and nuclear power station is provided with three road barriers in design, i.e. fuel can, reactor coolant loop border and containment.Under accident conditions, as long as three road barriers keep integrality, just can complete safe task.The key safety task that therefore, to the decomposition of security task, just need to keep three road barrier integrities from those.The key safety task comprises following six: remain subcritical; Maintain Core cooling; The maintaining heat trap; Maintain the integrality on reactor coolant loop border; Maintain the integrality of containment; Maintain the charging capacity of Main Coolant.
In order to guarantee the execution of above safe task in various accident conditionses, nuclear power station designs different systems or some has operated these tasks, and the present invention is these systems or Operation Definition more further task.Normally play a role under the accident conditions that these systems can be discussed in the present invention, will carry out certain operation or also need some subsystem supports system, the task that the present invention is these operations and subsystem definition more lower one deck.The decomposition that deepens continuously like this, until each operation for executing the task carried out.
In step 202, respectively availability task and security task are decomposed into to subtask layer by layer, and differentiate necessary subtask, determine the whole power plant task relevant with pulpit.
In step 203, the Task-decomposing termination rules is set, and pulpit inter-related task definite in step 202 is confirmed one by one by termination rules, the task of meeting termination rules stops decomposing, and the task of not meeting termination rules continues to get back in step 202 decomposes again.In the present embodiment, it can be from one or more with reference to selecting the described default termination rules of figure 1 that termination rules is set, and can also be to reset other termination rules.
In step 204, according to the task (needn't decomposing again of task) of decomposing fully in step 203, determine that power plant moves needed basic task information flow and task processing requirements.
Fig. 3 is the process flow diagram of the genetic algorithm that task is distributed according to an embodiment of the invention.In the present embodiment, the genetic algorithm that task is distributed starts from step 301.
In step 301, the information flow that the task analysis algorithm is determined carries out task analysis, differentiates and determines which information belongs to control task, and task analysis comprises determines various control informations and the execution information relevant to task.When carrying out task analysis, except analyzing correlation parameter, task, demand for control, can also be merged or be combined identical or inter-related task, to simplify control operation.
For example, in order to realize the operation of power plant, such as processing of accident conditions etc., need to carry out several tasks simultaneously.When carrying out task analysis, different high-level tasks can decomposite identical low level task, so just can merge " like terms "; The function that also has some tasks to realize is correlated with, and can, they appropriate combination, as a unit, be just that a kind of combined task is processed.So just can organize the information in various sources by certain actuating range, be convenient to operator and obtain relatively complete information in limited space.The embodiment of putting specific to pulpit man-machine interface and the dish tablecloth, be exactly on computer workstation, and the information that has been a certain task is put together; On back-up disk, the relative centralized arrangement of the equipment (comprising the equipment such as display instrument, registering instrument, controller) that has been a certain task.This strategy can be made a response operator fast, is also the foundation of parameter marshalling and equipment layout marshalling.
In step 302, by the control task identified in step 301, distribute to operator and machine has gone.When task is distributed, need to consider respectively the ability of operator and blind controller system, assign the task to suitable executor.In addition, when task is distributed, allocation criteria that can be default according at least one, for example according to task characteristic determine assign the task to which kind of carry out terminal (for example operator or machine) allocation criteria, according to objective condition determine take remote manually control the allocation criteria still controlled on the spot, according to the safety requirements under accident conditions carry out the task distribution allocation criteria, carry out at least one in the allocation criteria of task distribution according to the information block based on function.
In step 303, setting will be as the allocation criteria of basis for estimation, and in the present embodiment, it can be from one or more with reference to selecting the described default allocation criteria of figure 1 that allocation criteria is set, and can also be to reset other allocation criteria.The allocation criteria arranged in this step can be the allocation criteria from any appropriate different in step 302.For example, in step 302, based on reference to the described criterion 1 of figure 1, carrying out allocating task, in step 303, based on judging that with reference to the described criterion 2 of figure 1, criterion 3 and criterion 4 task is distributed, whether meet the demands respectively.
In step 304, judge according to the allocation criteria arranged in step 302 that task is distributed and whether meet the requirements, meet allocation criteria and distribute with regard to terminated task, do not meet allocation criteria and just continue to return step 302 and again reallocate, until meet allocation criteria.
In step 305, the distribution of finishing the work, the relevant execution terminal (for example operator and machine) of main control in can the control task executive system carried out being assigned with separately of the task of carrying out respectively.
