Description
Technical field
The invention belongs to nuclear power plant reactors to protect system at regular intervals experimental technique field, and in particular to a kind of nuclear power station reaction
Heap protection system at regular intervals experiment T2 test methods.
Background technology
Reactor protection system (RPS) major function is the complete of protection fuel can, primary Ioops pressure boundary and containment
Whole property, when protecting the parameter of system monitoring beyond the threshold value of some setting, input parameter is through overprotection system processing unit
Voting logic can export a series of actions (including the ad hoc action of shutdown breaker and safety) so as to reach safeguard protection work(
Energy.In order to ensure the availability of reactor protection system function and reliability, at regular intervals just need to protection system into
Row routine test, to verify the integrality of its function.
The routine test of reactor protection system is divided into be tested for T1, T2, T3, and wherein T2 experiments are mainly to signal processing
Unit is verified that experiment is taken bypass measure or carried out during shutdown, to avoid the injection due to stimulus, is caused anti-
Answer heap shutdown breaker or safe ad hoc malfunction.T2 tests the logic maincenter that main test object is protection system, to whole
The safe and stable operation of a nuclear power station is of great significance.Due to window time compared with it is short, test data amount is big, to T2 test
There is very high requirement in the required time and accuracy rate reliability.Traditional T2 experimental test scheme versatilities are poor, testing stand
It is single and have more complicated operation and maintenance condition, occupy a large amount of natively very nervous window times.For regular
T2 experiments in experiment individually develop, manufacture the input cost that testing stand also increases routine test naturally.
Invention content
It is an object of the invention to propose a kind of nuclear power plant reactor protection system at regular intervals experiment T2 test methods, to overcome
The shortcomings of the prior art.
In order to achieve the above objectives, the technical solution used in the present invention is：
A kind of nuclear power plant reactor protection system at regular intervals experiment T2 test methods, include the following steps：
Step 1：Confirm that selected system under test (SUT) is in the state that can be tested；
Step 2：Test system to be measured is simultaneously placed in bypass state by selected system to be tested；
Step 3：The controller for protecting system is placed in service mode, verifies system mode value, and is recorded to be measured before experiment
The output valve of test system generates journal file；
Step 4：Experiment is performed to selected test case；It is established using the maintenance network and system under test (SUT) of system under test (SUT)
Communication；Using the data for safeguarding network in system controller is protected and directly rewriting pilot passageway, experiment quilt is read in output terminal
Measured data, while comparison is made, and make conclusion (of pressure testing) according to experiment criterion and print out report with expected standard signal；
Step 5：After test, all force values are released, restore state and progress of the tested test system to before testing
Confirming, otherwise carry out positioning problems and troubleshooting, it is ensured that tested test system reverts to state before experiment, in order to avoid to protecting system
It impacts.
The single step of the step two supportive test process or automated execution test, and Real-time Feedback result of the test.
The step three will also make corresponding safeguard procedures, including forbidding input and output value and pressure in system under test (SUT)
Correlation, to ensure that system under test (SUT) is generated without shutdown condition.
Having the beneficial effect that acquired by the present invention：
Operation and maintenance of the present invention is more convenient, and can multiple experiments be optimized integration, be improved the utilization rate of window time.
The designing scheme can effectively solve the disadvantage that reactor protection system routine test device is complicated, maintenance difficulties are big, and can carry
High operation maintenance personnel tests the efficiency performed, shortens routine test window time.
For the present invention program using network is safeguarded as measurand injection testing signal, the output signal of system is protected in retaking of a year or grade,
Safeguard procedures are taken simultaneously to prevent triggering shutdown signal.The test output signal and expected result that acquisition is returned are compared,
Quickly handled using computer with food preservation test data, verify the correctness of tested protection system logic function and reliable
Property, it is automatic to export result and print record report.In the state for releasing mandatory parameters rapidly after the test, make tested test system
Or routing restoration is to reset condition.
Operating personnel can independently Selection experiment project, and result of the test can trace, improve test efficiency and autonomous
Property.It prevents stimulus from leading to the malfunction of reactor shutdown breaker using preventive means, greatly reduces routine test
Influence to reactor normal work.It is compared with other methods, this method only needs that casual network is accessed tested system at the trial
System without additionally accessing other test signals, reduces the human-equation error risk that experimental rig access protection system introduces, simplifies
Experiment and the complicated degree safeguarded.
