Description

The digital control system of the full brand-name computer group of nuclear power station and non-nuclear level control system, method
Technical field
The present invention relates to the nuclear power field, especially relate to digital control system and non-nuclear level control system, the method for the full brand-name computer group of a kind of nuclear power station.
Background technology
Because nuclear power is to the singularity of safety; Particularly behind generation Three Mile Island and Chernobyl nuclear accident of last century 70, the eighties; New technology is more conservative always in the application of nuclear power; It is later to cause DCS (Digital Control System, digital control system) based on computer technology, mechanics of communication and modern control theory really to be applied to the nuclear power generating sets control ratio fully.Before this, most nuclear power stations adopt combination instrument.The control model of having only the minority nuclear power station to adopt combination instrument to combine with small-sized DCS.
In the non-nuclear level DCS of two units of nuclear power station, having adopted with OSM (Optic Switch Module, optical switch module) is main industrial exchange network.Require high reliability, available rate owing to be used for the control of nuclear power plant system, equipment, therefore, the optical fiber ring network of being made up of OSM has all been adopted in the communications at different levels of non-nuclear level DCS in this project, realizes the fault-tolerant requirement of single fault.In redundant looped network, something must be done to avoids network redundancy to connect caused circulation.To two kinds of redundant connected modes of actual capabilities, redundant looped network in the promptly same network segment and the redundancy between the different segment connect, and avoid the round-robin scheme following:
To the redundant looped network in the same network segment, as shown in Figure 1, constitute a redundancy loop l network by 4 OSM, have the single fault fault tolerance.According to the OSM model of concrete use, adopt optical cable or industrial twisted-pair feeder to connect between the OSM.7,8 ports of OSM are used for loop network, and 1 to 6 port is used to articulate the various websites of non-nuclear level DCS, such as AP (Automation Processor; Automatic processor), CM (Communication Module; Communication module), PU (Processing Unit, process unit), SU (Server Unit, server unit), XU (eXchange Unit; Information exchange unit), OT (Operation Terminal; Operating terminal) etc., can certainly be used for and being connected of other network segments, such as being connected of Plant Bus (plant bus) and Train Bus (island bus).Because this loop network has the transmitted in both directions function; If not taking Redundancy Management mechanism comes transmitted in both directions is limited; The message that transmitted of 7,8 ports through OSM will unrestrictedly circulate in ring so, exhausts all bandwidth of ring, causes normal data communication to carry out.Compare revocable Redundancy Management pattern among the IEEE802.1d, normal fixing RM (Ring Management, the loop network management) pattern that adopts, as shown in Figure 2.When making up a loop network, must specify one and can only have an OSM to be responsible for the Redundancy Management of this loop network.In this example, OSM1 is set to the RM pattern, and OSM1 will send test packet (Test package) from 7 ports periodically, pass through 8,7 ports of OSM3 successively, 8,7 ports of OSM4, and 8,7 ports of OSM2,8 ports through OSM1 return OSM1 at last.This test is two-way, and promptly OSM1 also sends test packet through 8 ports simultaneously, passes through 7,8 ports of OSM2 successively, 7,8 ports of OSM4, and 7,8 ports of OSM3,7 ports through OSM1 return OSM1 at last.If loop network does not have fault, this test packet will successfully return OSM1 through after the certain delay so, and this time-delay can be set, but can not be above 50 milliseconds.In this case, 8 ports of OSM1 can not transmitted common data message, but can the transmitted test message.Like this, avoided the generation of loop network on the one hand, realized supervision on the other hand looped network.If fault has taken place loop network, such as other certain OSM faults, perhaps the somewhere between OSM connects fault.So, this test packet will can successfully not return OSM1 in the time-delay of appointment.In this case, OSM1 recognizes that loop network breaks down, and fair immediately 8 ports are transmitted common data message, and this has just guaranteed, in when, in the loop network single failure taking place when, and the operate as normal of general data communication.
Connect to the redundancy between the different segment, as shown in Figure 3, the OSM model according to reality is used connects two network segments with autonomy function through two optical cables or twisted-pair feeder, to realize two redundant data exchanges between the network segment.In this example, the network segment 1 is as central site network, and 1 port of its OSM1 and OSM2 is connected respectively to OSM1 and the OSM2 in the network segment 2.Between the OSM1 and OSM2 of the network segment 1, special configuration be used for being responsible for the redundant link management that connects between the network segment, like the L1 among the figure.In order to realize this function, OSM1 and OSM2 need pass through the DIP mode switch in the network segment 1, are set to main (Master) and subsequent use (Standby) respectively.After being provided with like this, when between these two network segments two redundant connections all just often, be connected (that is Master connection) between 1 port of 1 port of the communication between the network segment 1 and the network segment 2 through the OSM1 of the network segment 1 and the OSM1 of the network segment 2 carried out.Breaking down if Standby connects, also is like this.Break down when Master connects, through the Redundancy Management link, the OSM2 of the network segment 1 will learn, carries out thereby communication between the network segment is switched to the Standby connection.If fault recovery then can connect the Master that communication between the network segment switches to acquiescence again and carries out.Whenever, have only the communication connection of a side to work, avoid producing circulation and exhausted the limited network bandwidth.
Yet, get into field adjustable after the stage at No. 4 units, after promptly all non-nuclear level DCS equipment of 3,4 and No. 8 units all put into operation, serious grid communication abnormality phenomenon took place many times in the non-nuclear level DCS of 3,4 and No. 8 units.Cause the exchange of the real time data between the AP in unit, and the exchanges data between operation monitoring subsystem and the autonomous control subsystem can't be carried out normally all.And also cause between unit, the real-time information exchange can not normally be carried out.Had a strong impact on the safe and reliable operation of nuclear power plant.Through a large amount of diagnosis with analyze to find, cause the former of aforementioned disadvantages because: close some network node of DCS carrying out some specific system configuration modification, owing to have message exchange between most of network node.Therefore, after these network nodes are closed, can cause other and these network node to have the network node of exchanges data, its mail to these the network message of closed node can not arrive destination node.Network characteristic based on switch; These messages will flood at the network of relation switch; Longer when the duration that floods, and the message amount that floods is very for a long time, with seriously exhausting the limited network bandwidth; And then cause in the unit and unit between normal data exchange can't carry out, reduced the efficient of network exchange.

Embodiment
Before the non-nuclear stages of digital control system of the full brand-name computer group of explanation nuclear power station of the present invention; Do following introduction earlier: the full brand-name computer group of nuclear power station generally includes two units and a public supply part; Wherein, Public supply partly is used to unit public water, electricity, gas is provided, and for example, comprises 1, No. 2 unit and No. 9 units (public supply part) in the full brand-name computer group of first phase of certain nuclear power station; The full brand-name computer group of second phase of certain nuclear power station comprises 3, No. 4 units and No. 8 units, and full brand-name computer group of three phases of certain nuclear power station comprises 5, No. 6 units and No. 7 units (public supply part).In addition, what also need explain is when actual motion, can only move a unit or move two units simultaneously according to the size or the unit repair of external electrical network workload demand.
The full brand-name computer group of nuclear power station DCS is made up of the nuclear level TXS (the special digital control system of AREVA company) of AREVA and non-nuclear level TXP (automatic system of the Siemens's digital control system) platform of Siemens.Every unit disposes respectively that a cover function is improved relatively and DCS independently.Wherein, nuclear level DCS is used to realize RPS (Reaction Protection System, reactor protection system) and RGL (Reaction Power Control System; Reactor power control system); Be the control and the reactor core control of 1E level equipment, but not nuclear level DCS is as shown in Figure 4; Be used for SR (Safety Related; Safety is relevant) with the control of NC (Non-Classification, not classification) equipment, the normal running monitoring platform of all devices that non-nuclear level DCS also controls as nuclear level, non-nuclear level DCS.Be divided into automatic key-course Level1 (corresponding to AS620 (control automatically) subsystem of TXP system) and operation monitoring layer Level2 (corresponding to OM690 (operation monitoring) subsystem of TXP system) among the non-nuclear level of the every cover DCS again.According to the division of TXP function, Level1 mainly is made up of AS620, therefore, also Level1 is called autonomous control subsystem sometimes.Level2 mainly is made up of OM690, therefore, also Level2 is called the operation monitoring system sometimes.
As shown in Figure 5; Among the non-nuclear grade DCS with the full brand-name computer group of second phase of certain nuclear power station; In public supply part (No. 8 unit Unit8), for some on-the-spot process systems, like three wastes disposal system (KSN hereinafter referred to as); It belongs to the common sparing of No. 3 units (Unit3), No. 4 units (Unit4), and they need be by 3, No. 4 common complete operations of unit and supervision.No. 8 the non-nuclear level of unit DCS has only disposed autonomous control subsystem, does not dispose independently operation monitoring subsystem.The non-nuclear level DCS of No. 8 units realizes the automatic control of No. 8 on-the-spot process equipments of units, and to the operation monitoring of these process equipments, then in the operation monitoring subsystem of 3, No. 4 units, realizes.In addition; For the on-the-spot process equipment of the only a few in 3,4 units; Like DVN (Nuclear Auxiliary Building Ventilation, nuclear auxiliary building ventilating system) system, though they are controlled by a unit in 3,4 units in autonomous control subsystem; But at the operation monitoring subsystem, they need intersect supervision between two units.For realizing above-mentioned function, set up redundant industrial exchange network framework between the non-nuclear level DCS of 3,4 and No. 8 units.Wherein, the autonomous control subsystem network design that the Plant Bus of 3, No. 4 units and No. 8 units are unique redundant exchange link, through these links, realized the exchange of information between 3,4 and No. 8 units.
In the non-nuclear stages of digital control system of the full brand-name computer group of nuclear power station of the present invention; This full brand-name computer group comprises at least one unit and a public supply part; And the non-nuclear stages of digital control system of each unit comprises first autonomous control subsystem and the first operation monitoring subsystem that communication connects; The non-nuclear stages of digital control system of public supply part comprises second autonomous control subsystem; Said first autonomous control subsystem comprises the plant bus that is used to realize information acquisition and distribution, and second autonomous control subsystem carries out message exchange through said plant bus and first autonomous control subsystem and the first operation monitoring subsystem.Especially explanation is that first autonomous control subsystem also comprises the Network Isolation filter module, for example, can select the Scalance S602 Network Isolation filter module of Siemens Company for use.And; Said Network Isolation filter module is arranged between second autonomous control subsystem and the plant bus; Said Network Isolation filter module is used for the physical address according to network message; Transmit this network message to the website relevant, and stop this network message to be broadcast in the machine group network that has nothing to do with said physical address with said physical address.Explanation is in addition, can select a unit of operation or two units according to the size of load.
Non-nuclear stages of digital control system with the full brand-name computer group of the described nuclear power station of Fig. 6 is that example specifies below, and this nuclear power station comprises two units (i.e. No. 3 unit Unit3, No. 4 unit Unit4) and public supply part (i.e. No. 8 unit Unit8).And the non-nuclear stages of digital control system of each unit comprises autonomous control subsystem and operation monitoring subsystem that communication connects, specifies this two sub-systems below:
Autonomous control subsystem mainly has the fault-tolerant redundant ring network Plant Bus (plant bus) of single fault by 1; 5 have the fault-tolerant redundant ring network Train Bus (island bus) of single fault, the AP of 42 pairs of redundancies (Automation Processor, automatic processor); 8 couples of redundant CM (Communication Module that are used for non-nuclear level DCS and dedicated control system communication; Communication module, not shown), 1 clock server (not shown).Wherein, Plant Bus, Train Bus mainly are made up of Siemens industry OSM (Optic Switch Module, optical switch module).Redundant apportion and safety classification according to automatic processor, the handled control task of communication module; Be that A row SR, A row NC, B row SR, B row NC, A are listed as not classification NC+ (being used for CM); They are articulated to respectively on 5 Train Bus with corresponding classification and apportion, and these 5 Train Bus are articulated on the Plant Bus again.The major function of autonomous control subsystem is: through being articulated to the various collection FUM (function module) of AP, the physical signalling of the various process system equipment in scene is collected among the AP, after AP accomplishes various control algolithms; Generate corresponding steering order automatically, through various output FUM (functional module), on-the-spot topworks is exported in instruction again; In addition, signal that these are gathered and instruction are according to concrete configuration setting; Also possibly be transferred to PU (the Processing Unit of operation monitoring subsystem; Process unit) carry out performance computation, perhaps (through PU) further is transferred to the OT (Operation Terminal, operating terminal) of operation monitoring subsystem) show in real time; Perhaps be transferred to SU (the Server Unit of operation monitoring subsystem; Service unit) files,, perhaps export to Level3 (infosystem outside the venue) etc. so that analyze afterwards.
For some equipment; Under some control model; The operator can carry out the remote manual intervention at the operation monitoring subsystem; The operator goes up corresponding equipment operation indication window input manual command through OT, and this manual command is successively through network, PU, Plant Bus, Train Bus, AP, the output FUM of operation monitoring subsystem, and final arrival is positioned at on-the-spot topworks or other dedicated control system.CM also has similar characteristics, and difference is the not direct and on-the-spot process equipment interface of CM, but with the dedicated control system interface.Such as; For DCS and TCS (Turbine generator Control and Protection System; Steam turbine control and protection system) communication in, control, protection, operation and the supervision of T/G (Turbine and Generator, turbodynamo) are realized by TCS; It is an autonomous system, can realize automatic control, protection, operation and the supervision of T/G independently.But, in view of the advanced control room design concept, MCR (Main Control Room; Master-control room) no longer places the OT of TCS, and only place the OT of DCS, therefore; Normally in service in nuclear power plant, the OT that operation of originally in the OT of TCS, accomplishing and supervision need be incorporated into non-nuclear level DCS accomplishes.Therefore, the non-nuclear level of 3, No. 4 machines DCS has designed a pair of CM respectively and has been used for the message exchange with TCS.
The operation monitoring subsystem mainly has the fault-tolerant redundant ring network Terminal Bus (terminal bus) of single fault, a pair of redundant PU, a pair of redundant SU, 3 by 1 and is used for the XU (eXchange Unit, information exchange unit) of non-nuclear level DCS and Level3 system communication, 15 operating terminal OT, engineer stations' composition.The major function of operation monitoring subsystem is: PU receives the various real time datas that autonomous control subsystem generates, and in PU, accomplishes performance computation, perhaps on OT, shows in real time, perhaps in SU, files, and perhaps gives Level3 system through XU.
Receive the operations of operators instruction through OT, and send it to autonomous control subsystem.In addition; BUP (Back-Up Panel; Back-up operation during the back-up operation dish), as the operation monitoring subsystem failure, surveillance and operation monitoring subsystem described above have similar function; Structurally walk abreast with the operation monitoring subsystem, they are while and autonomous control subsystem interface.
In this embodiment; The autonomous control subsystem of public supply part carries out message exchange through the plant bus of each unit and the non-nuclear stages of digital control system of each unit; And; The autonomous control subsystem of No. 3, No. 4 units all also comprises the Network Isolation filter module, and said Network Isolation filter module is arranged between the plant bus of autonomous control subsystem and each unit of public supply part, and said Network Isolation filter module is used for the physical address according to network message; Transmit this network message to the website relevant, and stop this network message to be broadcast in the machine group network that has nothing to do with said physical address with said physical address.
About the Network Isolation filter module, in actual motion, need be provided with isolating filtering policy according to the exchange situation of website signal between the unit of reality.For example, below just allow signal exchange under several kinds of situation, otherwise will be by the locking of Network Isolation filter module.
1) first kind of situation: the Network Isolation filter module is transmitted this network message between a plurality of process units of a plurality of automatic processors of second autonomous control subsystem and the first operation monitoring subsystem.For example in the embodiment shown in fig. 6, all AP need carry out communication with the PU of the redundancy of No. 3 machines, No. 4 machines in No. 8 units, also realizes the operation monitoring of the operation monitoring subsystem of No. 3 units, No. 4 units to No. 8 machine equipments.Because all possibly there are communication in A, the B side of A, B side and the redundant AP of redundant PU, also are to be both-way communication between PU1 and AP-A, PU1 and AP-B, PU2 and AP-A, PU2 and the AP-B.Therefore, when in the Network Isolation filter module, being provided with, these links must be by locking.
2) second kind of situation: when the quantity of said unit is two; Said Network Isolation filter module only sends periodic time synchronized message with the clock server in first automatic control system of one of them unit and is forwarded to second autonomous control subsystem according to the physical address in the network message.What this need explain be, when design DCS, No. 8 the non-nuclear level of unit DCS does not dispose independent time server, and its time sync message comes from unit No. 3.According to the Design of Automatic Control System standard, two or above time synchronized message can not be arranged in the same network segment simultaneously, otherwise saltus step takes place in system time possibly, cause the time of video data in the operation monitoring subsystem disorderly.Therefore; In the embodiment shown in fig. 6; Exchange for the time synchronized message in 3,4 and No. 8 units; The periodicity time synchronized message of the time server of No. 3 non-nuclear level of machine DCS sends to the non-nuclear level of machine DCS No. 8; And the time synchronized message of No. 8 non-nuclear level of machine DCS does not allow to return the non-nuclear level of machine DCS No. 3, and the periodicity time synchronized message of the time server of No. 4 non-nuclear level of machine DCS does not allow to send to machine DCS No. 8, and the time message of No. 8 non-nuclear level of machine DCS does not allow to send to the non-nuclear level of machine DCS No. 4 yet.
3) the third situation: when the quantity of said unit is two; Said Network Isolation filter module is according to the physical address in the network message; Realize the parallel communication of the automatic processor between first autonomous control subsystem, and stop the intersection communication of the automatic processor between first autonomous control subsystem.For example, in the embodiment shown in fig. 6, the AP of signal exchange is arranged between 3,4 and No. 8 units; Its normal communication should not be limited; Because it is parallel that the communication in the autonomous control subsystem between redundant AP only possibly exist, and can not have the intersection communication, such as there being signal exchange between redundant AP first and the redundant AP second; The communication link of actual capabilities is the A side of AP first and the A side of AP second; The B side of AP first and the B side of AP second are carried out both-way communication, and perhaps there is not communication in the B side of the A side of AP first and AP second between the A side of the B side of AP first and AP second.
When implementing to install the measure of Network Isolation filter module additional, comprehensive above-mentioned 3 points have carried out corresponding setting to each Network Isolation filter module.In addition; Preferably; Wherein when being provided with, also have the function of some details to need to be provided with; Allow the network bandwidth that takies such as the communication link of each permission, like this, the Network Isolation filter module also is used for according to the number of signals of the network message that allows the to transmit potential link assignment corresponding bandwidth for this Communications service.Therefore, reasonably be provided with and make isolation effect more obvious, and guarantee the high efficiency and the stability of network exchange.
In addition, replace or increase OSM of new generation, for example, in the embodiment shown in fig. 6,, need on the existing network basis, change and add the switch of a small amount of Siemens a new generation respectively to 3, No. 4 machines.In Plant Bus; Use has said function; But algorithm is more advanced, more powerful Scalance X204-2 switch is replaced that OSM of existing responsible loop network Redundancy Management; In 5 Train Bus, need increase a Scalance X204-2 switch respectively, and will transfer on the switch of this increase by the loop network Redundancy Management function that existing OSM is responsible for.
The present invention also constructs the digital control system of the full brand-name computer group of a kind of nuclear power station, comprises nuclear stages of digital control system and above-described non-nuclear stages of digital control system.
Fig. 7 is the process flow diagram of the non-nuclear stages of digital control method embodiment one of the full brand-name computer group of nuclear power station of the present invention, and based on the non-nuclear stages of digital control system of the full brand-name computer group of above-mentioned nuclear power station, this non-nuclear stages of digital control method comprises:

In a preferred embodiment of non-nuclear stages of digital control method, step S30 comprises:
S31. the Network Isolation filter module is according to the physical address in the network message; Between a plurality of process units of a plurality of automatic processors of second autonomous control subsystem and the first operation monitoring subsystem, transmit this network message; Wherein, Said second autonomous control subsystem comprises a plurality of automatic processors, and the said first operation monitoring subsystem comprises a plurality of process units, and automatic processor and process unit are all redundant to be provided with.
