Description
Technical field
The present invention relates to nuclear power plant's reactor protection system design fields, and in particular to one kind is applied to protection system of nuclear power plant
The PTR water level signal processing method of system.
Background technique
For reply reactor protection system software because failure leads to the potential risk for losing automatic protection functions, main control room
In be provided with emergency control panel, emergency control panel is the hard logic circuit built based on relay, it is ensured that occur emergency work condition
When being superimposed safety level software common mode failure, operator remains to bring reactor into safe condition.PTR (reactor refuling pond and
The cooling and processing system of Spent Fuel Pool) important parameter one of of the water level signal as reactor protection system, at logic
The relationship of logical "and" is carried out in reason with the manual control commands from emergency control panel.
After common mode failure occurs for existing nuclear power plant 1E grades of software, PTR water level signal or accidentally hair PTR water level letter can not be sent out
Number, cause operator to occur what driver can not be operated when emergency control panel manual confirmation pacifies note and peace spray signal executes
Situation, there are the risks that accident further deteriorates.
Summary of the invention
After common mode failure occurs the technical problem to be solved by the present invention is to existing nuclear power plant 1E grades of software, it can not send out
PTR water level signal or accidentally hair PTR water level signal cause operator to pacify note in emergency control panel manual confirmation and pacify spray signal and execute
When there is the case where driver can not be operated, the risk further deteriorated there are accident is, and it is an object of the present invention to provide a kind of application
In the PTR water level signal processing method of nuclear power plant's protection system, solve the above problems.
The present invention is achieved through the following technical solutions:
A kind of PTR water level signal processing method applied to nuclear power plant's protection system, comprising the following steps: S1: to scene
PTR water level signal carries out isolation distribution；S2: the live PTR water level signal after isolation distribution is subjected to threshold value comparison and logical table
Certainly；The threshold value comparison and logic voting carry out in emergency control panel.
In the prior art, after common mode failure occurs for nuclear power plant 1E grades of softwares, PTR water level signal or accidentally hair PTR can not be sent out
Water level signal, causing operator driver occur when emergency control panel manual confirmation pacifies note and peace spray signal executes can not carry out
The case where operation, there are the risks that accident further deteriorates.
Consider for safe operation, the protection system PTR water level signal of nuclear power plant is in logical process and from urgent control
The manual control commands of disk processed will carry out the relationship of logical "and", so needing to meet PTR simultaneously in control peace note and peace spray
Water level signal and manual control commands, if thus will appear PTR water level signal when the error occurs, manual control commands are nothings
Method directly controls peace note and peace spray；And the present invention is by carrying out isolation distribution to live PTR water level signal, and in emergency control panel
In directly carry out threshold value comparison and logic voting, can effectively reduce 1E grades of softwares of reactor protection system and emergency control panel
Reciprocal effect, reduce the influence emergency control panel when common mode failure occurs for 1E grade softwares of reactor protection system and correctly execute it
A possibility that function.
Further, isolation distribution described in step S1 is carried out in the side 1E.
Further, the logic voting in step S2 uses 2oo3 logic.
Further, further comprising the steps of: S3: live PTR water level signal logic voting after in logical process with
Manual control commands from emergency control panel carry out the relationship of logical "and".
Consider for safe operation, live PTR water level signal is after logic voting in logical process and from urgent control
The manual control commands of disk processed carry out the relationship of logical "and", in conjunction with threshold value comparison and logic voting in emergency control panel into
Row can achieve and reduce the loss of maloperation bring, and may insure that emergency work condition superposition safety level software common mode is occurring
When failure, operator remains to bring reactor into safe condition.
Compared with prior art, the present invention having the following advantages and benefits:
A kind of PTR water level signal processing method applied to nuclear power plant's protection system of the present invention, can effectively be reduced anti-
It answers heap to protect the reciprocal effect of system 1E grades of software and emergency control panel, reduces and occur altogether in 1E grades of softwares of reactor protection system
A possibility that emergency control panel correctly executes its function is influenced when mould failure.
Detailed description of the invention
Attached drawing described herein is used to provide to further understand the embodiment of the present invention, constitutes one of the application
Point, do not constitute the restriction to the embodiment of the present invention.In the accompanying drawings:
Fig. 1 is schematic diagram of the embodiment of the present invention.
Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, below with reference to embodiment and attached drawing, to this
Invention is described in further detail, and exemplary embodiment of the invention and its explanation for explaining only the invention, are not made
For limitation of the invention.
Embodiment
As shown in Figure 1, a kind of PTR water level signal processing method applied to nuclear power plant's protection system of the present invention, including with
Lower step: isolation distribution S1: is carried out to live PTR water level signal；S2: the live PTR water level signal after isolation distribution is carried out
Threshold value comparison and logic voting；The threshold value comparison and logic voting carry out in emergency control panel.
Consider for safe operation, the protection system PTR water level signal of nuclear power plant is in logical process and from urgent control
The manual control commands of disk processed will carry out the relationship of logical "and", so needing to meet PTR simultaneously in control peace note and peace spray
