Description
Technical field
The present invention relates to nuclear power station technical field, more particularly, relate to a kind of digital backup panel for nuclear power plant.
Background technology
Along with the develop rapidly of digitizer control techniques, part adopts the nuclear power plant of digitizer Ore-controlling Role to run for many years and possesses the condition of ripe development in the world, and new nuclear power projects also all have employed digitizer Ore-controlling Role.Compared with analog control technique, digitizing technique has obvious technical advance and advantage, is also conducive to safe condition and the stable operation level of improving nuclear power plant.Digitizer Ore-controlling Role is adopted to become the inexorable trend of nuclear power developing.
Master control room of nuclear power station design also progressively moves towards totally digitilized master-control room from conventional master-control room along with the development of digitizing technique.Zhong Guang core group, from ridge Australia second phase project, all adopts computerized information and control system to monitor power plant in master-control room.Nuclear power generating sets, after employing digitizer Ore-controlling Role (DCS), are considered the possibility all losing power station computerized information and control system, need be arranged standby monitoring means in master-control room.As losing the back-up operation means that computing machine is main monitor mode, it need meet following principle when designing:
1, under unit accidental conditions, when main monitoring means (i.e. computerized information and control system) lost efficacy, if the out-of-service time is less than N hour (N determines according to the actual conditions difference of concrete unit), standby monitoring means should monitor and unit be remained on the power operating states of stable state;
2, under unit accidental conditions, when the inefficacy being greater than N hour appears in main monitoring means, standby monitoring means should be closed down unit unit is remained on safe condition;
3, when unit failure operating mode and main monitoring means lost efficacy, no matter be lost efficacy during accident conditions, or have an accident at standby monitoring means run duration (namely main monitoring means lost efficacy), on standby monitoring means, all should monitor or perform security function after corresponding accident by corresponding accident program, unit is reached and maintains safe condition.
At present, CPR1000 project nuclear power station advanced main control room is on the basis that totally digitilized blind controller system applied by nuclear power station, and adopt digitizing man machine interface to be operating as master, the one be combined with conventional back-up disk spare phase designs.
Back-up disk considers when the monitor mode of main control and monitor console based on computing machine is unavailable, and the equipment based on hardwire of safe shutdown state also can be brought in power station by maintenance nuclear power station within a certain period of time safe operation.Back-up disk and main control and monitor console adopt two to overlap diverse platform (a set of is hardware, and a set of is software), thus achieve the diversity of platform, prevent from occurring common mode failure at a set of platform interior and losing monitoring function.
Referring to Fig. 1, is nuclear power station back-up disk annexation schematic diagram in prior art.As safe level site control cabinet 21 in Fig. 1 is connected to safe level instrument and controller 11, thus carry out the communication of safe level instrument control signal with safe level instrument and controller 11, comprise the equipment state signal gathering safe level instrument and controller 11, and sent to by equipment controling signal safe level instrument and controller 11 to realize controlling.Equally, non-security level site control cabinet 22 is connected to non-security level instrument and controller 12, thus carry out the communication of non-security level instrument control signal with non-security level instrument and controller 12, comprise the equipment state signal gathering non-security level instrument and controller 12, and sent to by equipment controling signal non-security level instrument and controller 12 to realize controlling.Safe level site control cabinet 21 and non-security level site control cabinet 22 carry out communication with main control and monitor console (not shown) and back-up disk 30 simultaneously, carry out the logical process of I/0 process variable.The annexation of back-up disk 30 is illustrate only in Fig. 1, in prior art, back-up disk 30 adopts analogue instrument 31 to realize, safe level analogue instrument and non-security level analogue instrument can be comprised, be connected to safe level site control cabinet 21 and non-security level site control cabinet 22 respectively by hardwire, and then show whole safe level instrument control signal and non-security level instrument control signal by the mode of analogue instrument.Although safe level display (S-VDU) 32 and safe level display (S-VDU) processor 33 may be comprised in minority back-up disk 30, wherein, the Partial security level instrument control signal of safe level site control cabinet 21 can show after (S-VDU) processor 33 carries out display and control by safe level, show at safe level display (S-VDU) 32, but what safe level display (S-VDU) 32 showed only has few a part of safe level instrument control signal, most safe level instrument control signal and whole non-security level instrument control signals are still shown by analogue instrument 31.That is on existing back-up disk 30, the overwhelming majority controls and shows all to adopt custom hardware equipment, is connected with site control cabinet by hardwire.And when carrying out the topological design of back-up disk, because the analogue instrument adopted causes that hardware device size is large, Pan Tai takes up room greatly, the frequent movement of operator's needs when executing the task carrys out localizing objects operating equipment.
