Description
Technical field
The invention belongs to nuclear process control system operation and maintenance fields, and in particular to a kind of PWR nuclear power plant core grade number
Change I＆C system operation and maintenance method.
Background technology
The digitalized I＆C system of core (hereinafter referred to as KCS) is security system important in digital instrument control system of nuclear power plant,
Its major function is by shutdown and (or) to start engineered safeguards features, under unusual service condition or accident conditions to prevent or subtract
The damage of light reactor core and coolant system component, protects the integrality of three big nuclear safety barriers, avoids causing radioactive substance big
Amount effusion, protects nuclear power plant's ambient enviroment not contaminated and personnel safety.
KCS systems need to control it configuration verification, logic function routine test, interim control change after putting into operation
The more operation and maintenance such as implementation and revocation, in particular according to nuclear power relevant laws and regulations and directive/guide requirement, to ensure that core is digitalized
The reliability of I＆C system needs to carry out routine test to its logic function.In common engineering, itself have in view of KCS systems
There is stronger System self-test function, therefore, does not design special experimental rig and implement logic function experiment to it.However, practical
Upper KCS System self-test can not completely cover the diagnosis of software logic state, and signal existing for internal system is connect firmly
Line can not be checked, therefore there is still a need for for KCS logic function routine test development experiments devices, to realize to KCS logics
The integrity authentication of function.
Traditional KCS systems control configuration is verified, and generally use manually mode examines control configuration version
It looks into, be required to carry out hand inspection item by item to up to a hundred grouping states every time and compare, have and expend time, labor intensive and Yi Renyin
The shortcomings that error.
For implementing during unit uplink and downlink and the interim control of revocation change work, be required to every time more people one by one into
The imperative operation of row signaling point, semaphore is more and is important reactor protection signal, and being also easy to produce human-equation error leads to weight
The risk for wanting equipment malfunction to make.
For logic function routine test, traditional experiment mode is to use to be manually injected into electric signal and acquisition feedback signal simultaneously
Judge the mode of test result.Traditional experiment mode needs a large amount of signal source and manpower to support, frequently plug test cable or
Switching tests switch, and the used time is longer, and execution window is limited during overhaul, and the complex work of the intensive manpower of short time is
Work brings larger risk.
Above-mentioned operation and maintenance, have that work risk is high, manual operation load is big, automatization level is low, error-prone etc.
Problem brings larger security risk while taking time and effort to the operation of unit.In view of the above problems, a kind of special there is an urgent need for developing
For the method for the digitalized I＆C system operation and maintenance of core so that the implementation of system operation maintenance work is safer, it is quick,
It is convenient, efficient.

Second is that automation sets KCS system test relevant variable values to the preset particular state of script file, meet
The initial reguirements of follow-up test signal；
5. executing experiment script：It is divided into subgroup according to the function of protection system, partition functionality module in subgroup, execution pattern point
Two kinds：
One kind is individual feature experiment in subgroup；
One is the experiment automatized batches of optional function to execute, and by the experiment script for selecting to need, realizes multiple work(in subgroup
It can script verification；
6. testing process control：During experiment, automatic operating script, and correlated variables is changed by communication signal, automatically
The collection test result of change, and be compared with desired value, if experiment passes through, then prompt the script to run successfully, software is automatic
The reset signal of change carries out next group of function script experiment to original state；
Such as in certain group function test scenario process, test result is incorrect, then termination test, and restores the system to initial shape
State, while providing the signal of appearance exception during experiment；
The record of entire experiment process is recorded in the form of log files, for testing crew analysis experiment process and failure cause；
7. the carry out system recovery automated：After the test, script is restored by operating system, due to first in recovery controller
Beginningization and generate signal block, by signal condition all in controller be restored to experiment before state；
8. print record：The corresponding all script implementing results of one subgroup are that " passing through " represents current subgroup logic function examination
It tests and passes through；
14 subgroup logic function experiments are completed by representing the experiment of KCS logic functions；
According to regulation format print output, the part as test report file is achieved test result；
