Description

The digital control system of the full brand-name computer group of nuclear power station and non-core level control system, method
Technical field
The present invention relates to nuclear power field, especially relate to digital control system and non-core 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 after generation Three Mile Island and Chernobyl nuclear accident of last century 70, the eighties, new technology is always more conservative in the application of nuclear power, cause the DCS(DigitalControlSystem based on computer technology, mechanics of communication and modern control theory, digital control system) be really applied to completely nuclear power generating sets control more late.Before this, most nuclear power station adopts combination instrument.Only has the control model that minority nuclear power station employing combination instrument combines with small-sized DCS.
In the non-core level DCS of two units of nuclear power station, have employed with OSM(OpticSwitchModule, optical switch module) be main industrial exchange network.Due to control overflow high reliability, available rate for nuclear power plant system, equipment, therefore, in this project, the communications at different levels of non-core level DCS all have employed the optical fiber ring network be made up of OSM, realize single fault fault tolerance requirements.In redundant looped network, must take measures to avoid the circulation caused by network redundancy connection.For two kinds of redundancy link modes of actual capabilities, the redundant looped network namely in the same network segment and the redundancy link between different segment, avoid the scheme of circulation as follows:
For the redundant looped network in the same network segment, as shown in Figure 1, form a redundancy loop l network by 4 OSM, there is single fault fault tolerance.According to the concrete OSM model used, optical cable or industrial twisted-pair feeder between OSM, is adopted to connect.7 of OSM, 8 ports are used for loop network, and 1 to 6 ports are for mounting the various websites of non-core level DCS, such as AP(AutomationProcessor, automatic processor), CM(CommunicationModule, communication module), PU(ProcessingUnit, process unit), SU(ServerUnit, server unit), XU(eXchangeUnit, information exchange unit), OT(OperationTerminal, operating terminal) etc., the connection with other network segments can certainly be used for, such as PlantBus(plant bus) with TrainBus(island bus) connection.Because this loop network has transmitted in both directions function, if do not take Redundancy Management mechanism to limit transmitted in both directions, the message so transmitted by 7,8 ports of OSM will unrestrictedly circulate in ring, exhausts all bandwidth of ring, causes normal data communication to carry out.Compare revocable Redundancy Management pattern in IEEE802.1d, the RM(RingManagement that normal employing is fixing, loop network manages) pattern, as shown in Figure 2.When a structure loop network, one must be specified and an OSM can only be had to be responsible for the Redundancy Management of this loop network.In this example, OSM1 is set to RM pattern, and OSM1 will send test packet (Testpackage) from 7 ports periodically, successively through 8,7 ports of OSM3,8,7 ports of OSM4,8 of OSM2,7 ports, 8 ports finally by OSM1 return OSM1.This test is two-way, and namely OSM1 also sends test packet by 8 ports simultaneously, and successively through 7,8 ports of OSM2,7,8 ports of OSM4,7,8 ports of OSM3,7 ports finally by OSM1 return OSM1.If loop network does not have fault, so this test packet successfully will return OSM1 after certain time delay, and this time delay can set, but can not more than 50 milliseconds.In this case, 8 ports of OSM1 can not forward common data message, but can transmitted test message.Like this, avoid the generation of loop network on the one hand, achieve the supervision to looped network on the other hand.If loop network there occurs fault, such as other certain OSM faults, or the somewhere between OSM connects fault.So, this test packet successfully can not return OSM1 in the time delay of specifying.In this case, OSM1 recognizes that loop network breaks down, and permits the data message that 8 port repeats are common immediately, this guarantees, when there is single failure in loop network, and the normal work of general data communication.
For the redundancy link between different segment, as shown in Figure 3, according to the OSM model that reality uses, by two optical cables or twisted-pair feeder, the network segment that two have autonomy function is connected, exchange with the redundant data realized between two network segments.In this example, the network segment 1 is as central site network, and 1 port of itself OSM1 and OSM2 is connected respectively to OSM1 and OSM2 in the network segment 2.Between OSM1 and the OSM2 of the network segment 1, special configuration for the link management of redundancy link between the responsible network segment, as the L1 in figure.In order to realize this function, in the network segment 1, OSM1 and OSM2 needs by DIP mode switch, is set to respectively main (Master) and (Standby) for subsequent use.After arranging like this, when two redundancy links when between these two network segments are all normal, the connection (that is, Master connects) that the communication between the network segment 1 and the network segment 2 is passed through between 1 port of OSM1 of the network segment 1 and 1 port of the OSM1 of the network segment 2 is carried out.Breaking down if Standby connects, is also like this.When Master connect break down, by Redundancy Management link, the OSM2 of the network segment 1 will learn, thus communication between the network segment is switched to Standby connect carry out.If fault recovery, then the Master connection that communication between the network segment can be switched to again acquiescence is carried out.Whenever, only have the communication of side to connect and work, avoid and produce circulation and exhaust the limited network bandwidth.
But after No. 4 units enter the field adjustable stage, after namely all non-core level DCS equipment of 3,4 and No. 8 units all put into operation, there is serious grid communication abnormality phenomenon many times in the non-core level DCS of 3,4 and No. 8 units.Cause the Real Data Exchangs in unit between AP, and the exchanges data between operation monitoring subsystem and autonomous control subsystem all normally cannot be carried out.And also cause between unit, real-time information exchanges can not normally be carried out.Have a strong impact on the safe and reliable operation of nuclear power plant.Found by a large amount of diagnosis and analyzing, cause the reason of aforementioned drawback to be: carrying out some specific system configuration modification and close some network node of DCS, owing to there is message exchange between most of network node.Therefore, after these network nodes are closed, other and these network node can be caused to there is the network node of exchanges data, its network message mailing to these closed nodes can not arrive destination node.Based on the network characteristic of switch, these messages will flood at related network switch, longer when the duration that floods, and the message amount flooded very many time, by the network bandwidth limited for serious drain, and then cause in unit and between unit, normal data exchange cannot be carried out, reduce the efficiency of network exchange.

The full brand-name computer group DCS of nuclear power station is by the special digital control system of the He Ji TXS(AREVA company of AREVA) and the automatic system of non-core level TXP(Siemens Digital control system of Siemens) platform forms.Every platform unit configures a set of function comparatively perfect and independently DCS respectively.Wherein, core level DCS is used for realizing RPS(ReactionProtectionSystem; reactor protection system) and RGL(ReactionPowerControlSystem; reactor power control system); namely the control of 1E level equipment and reactor core control; and non-core level DCS; as shown in Figure 4; for SR(SafetyRelated; safety is relevant) and NC(Non-Classification; non-classification) control of equipment, the normal running monitoring platform of all devices that non-core level DCS also controls as core level, non-core level DCS.Often overlap the AS620(being divided into again automatic key-course Level1(to correspond to TXP system in non-core level DCS automatically to control) subsystem) and operation monitoring layer Level2(corresponding to the OM690(operation monitoring of TXP system) subsystem).According to the division of TXP function, Level1 forms primarily of AS620, therefore, sometimes also Level1 is called autonomous control subsystem.Level2 forms primarily of OM690, therefore, sometimes also Level2 is called operation monitoring system.
As shown in Figure 5, with in the non-core level DCS of the second phase of certain nuclear power station full brand-name computer group, in public supply part (No. 8 unit Unit8), for some site technique systems, as three-protection design system (hereinafter referred to as KSN), it belongs to the common sparing of No. 3 units (Unit3), No. 4 units (Unit4), and they need by 3, No. 4 common complete operations of unit and supervision.No. 8 unit non-core level DCS are only configured with autonomous control subsystem, do not configure independently operation monitoring subsystem.The non-core level DCS of No. 8 units realizes the automatic control of No. 8 Site for Unit process equipments, and the operation monitoring to these process equipments, then realize in the operation monitoring subsystem of 3, No. 4 units.In addition, for the only a few site technique equipment in 3,4 units, as DVN(NuclearAuxiliaryBuildingVentilation, nuclear auxiliary building ventilating system) system, although they in autonomous control subsystem by a unit allocation in 3,4 units, but at operation monitoring subsystem, they need to intersect between two units to monitor.For realizing above-mentioned function, between the non-core level DCS of 3,4 and No. 8 units, establish the industrial exchange network framework of redundancy.Wherein, autonomous control subsystem network design that PlantBus and No. 8 unit of 3, No. 4 units the is unique link exchange of redundancy, by these links, achieves the exchange of information between 3,4 and No. 8 units.
In the non-core 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-core stages of digital control system of each unit comprises the first autonomous control subsystem and the first operation monitoring subsystem of communication connection, the non-core stages of digital control system of public supply part comprises the second autonomous control subsystem, described first autonomous control subsystem comprises the plant bus for realizing information acquisition and distribution, and the second autonomous control subsystem carries out message exchange by described plant bus and the first autonomous control subsystem and the first operation monitoring subsystem.Especially illustrate, the first autonomous control subsystem also comprises Network Isolation filter module, such as, can select the ScalanceS602 Network Isolation filter module of Siemens Company.And, described Network Isolation filter module is arranged between the second autonomous control subsystem and plant bus, described Network Isolation filter module is used for according to the physical address in network message, forward this network message to the website relevant to described physical address, and stop this network message to be broadcast in the machine group network irrelevant with described physical address.Illustrate in addition, operation unit or two units can be selected according to the size of load.
Describe in detail for the non-core stages of digital control system of the full brand-name computer group of the nuclear power station described in Fig. 6 below, 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-core stages of digital control system of each unit comprises autonomous control subsystem and the operation monitoring subsystem of communication connection, the following detailed description of these two subsystems:
Autonomous control subsystem has the fault-tolerant redundancy ring network PlantBus(plant bus of single fault primarily of 1), 5 have the fault-tolerant redundancy ring network TrainBus(island bus of single fault), the AP(AutomationProcessor of 42 pairs of redundancies, automatic processor), 8 couples of redundancy CM(CommunicationModule for non-core level DCS and dedicated control system communication, communication module, not shown), 1 clock server (not shown).Wherein, PlantBus, TrainBus are primarily of Siemens's industry OSM (OpticSwitchModule, optical switch module) composition.The redundancy apportion of the control task handled by automatic processor, communication module and safety classification, namely A row SR, A row NC, B row SR, B row NC, A arrange non-classification NC+ (for CM), they are articulated on 5 TrainBus with corresponding classification and apportion respectively, and these 5 TrainBus are articulated on PlantBus again.The major function of autonomous control subsystem is: by being articulated to the various collection FUM(function modules of AP), the physical signalling of various for scene process system equipment is collected in AP, after AP completes various control algolithm, generate corresponding steering order automatically, again by various output FUM(functional module), on-the-spot topworks is exported in instruction, in addition, these collected signals and instruction, arrange according to concrete configuration, also the PU(ProcessingUnit of operation monitoring subsystem may be transferred to, process unit) carry out performance calculating, or (passing through PU) is transferred to the OT (OperationTerminal of operation monitoring subsystem further, operating terminal)) show in real time, or be transferred to the SU (ServerUnit of operation monitoring subsystem, service unit) file, to analyze afterwards, or export to Level3(infosystem outside the venue) etc.
For some equipment, under some control model, operator can carry out remote manual intervention at operation monitoring subsystem, operator is by equipment operating indication window corresponding on OT input manual command, this manual command is successively by the network of operation monitoring subsystem, PU, PlantBus, TrainBus, AP, output FUM, and final arrival is positioned at on-the-spot topworks or other dedicated control system.CM also has similar feature, and difference is CM directly and site technique equipment interface, but with dedicated control system interface.Such as; for DCS and TCS (TurbinegeneratorControlandProtectionSystem; steam turbine control and protection system) communication in; T/G (TurbineandGenerator; turbodynamo) control, protection, operation and supervision realized by TCS; it is an autonomous system, can realize the automatic control of T/G, protection, operation and supervision independently.But, in view of advanced control room design concept, MCR(MainControlRoom, master-control room) no longer place the OT of TCS, and only place the OT of DCS, therefore, in nuclear power plant normally runs, the operation originally completed in the OT of TCS and supervision need the OT being incorporated into non-core level DCS to come.Therefore, 3, No. 4 machine non-core level DCS devise a pair CM respectively for the message exchange with TCS.
Operation monitoring subsystem has the fault-tolerant redundancy ring network TerminalBus(terminal bus of single fault primarily of 1), a pair redundancy PU, a pair redundancy SU, 3 XU(eXchangeUnit for non-core level DCS and Level3 system communication, information exchange unit), 15 operating terminal OT, engineer stations' compositions.The major function of operation monitoring subsystem is: PU receives the various real time datas that autonomous control subsystem generates, and completes performance and calculates, or show in real time on OT, or file in SU, or give Level3 system by XU in PU.
Received the operational order of operator by OT, and send it to autonomous control subsystem.In addition, BUP(Back-UpPanel, back-up operation dish), as back-up operation, surveillance during operation monitoring subsystem failure, similar function is had with operation monitoring subsystem described above, structurally parallel with operation monitoring subsystem, they all simultaneously with autonomous control subsystem interface.
In this embodiment, the autonomous control subsystem of public supply part carries out message exchange by the plant bus of each unit and the non-core stages of digital control system of each unit, and, No. 3, the autonomous control subsystem of No. 4 units all also comprises Network Isolation filter module, and described Network Isolation filter module is arranged between the autonomous control subsystem of public supply part and the plant bus of each unit, described Network Isolation filter module is used for according to the physical address in network message, forward this network message to the website relevant to described physical address, and stop this network message to be broadcast in the machine group network irrelevant with described physical address.
About Network Isolation filter module, in actual motion, need the exchange situation of website signal between the unit according to reality, isolation filtering policy is arranged.Such as, just allow signal exchange in several situation below, otherwise will by the locking of Network Isolation filter module.
1) the first situation: Network Isolation filter module forwards this network message between multiple automatic processor and multiple process units of the first operation monitoring subsystem of the second autonomous control subsystem.Such as in the embodiment shown in fig. 6, AP all in No. 8 units needs to carry out communication with the PU of the redundancy of No. 3 machines, No. 4 machines, also realize No. 3 units, No. 4 units operation monitoring subsystem to the operation monitoring of No. 8 machine equipments.Because A, B side of redundancy PU and A, B side of redundancy AP all may exist communication, be also PU1 and AP-A, PU1 and AP-B, be both-way communication between PU2 and AP-A, PU2 and AP-B.Therefore, when arranging in Network Isolation filter module, these links must not be blocked.
2) the second situation: when the quantity of described unit is two, clock server in first automatic control system of one of them unit, according to the physical address in network message, is only sent periodic time synchronized message repeating to the second autonomous control subsystem by described Network Isolation filter module.It should be noted that at this, when designing DCS, No. 8 unit non-core level DCS do not configure independent time server, and its time sync message comes from No. 3 units.According to Design of Automatic Control System specification, two or more time synchronized messages can not be had in the same network segment, otherwise there is saltus step possibly in system time simultaneously, cause the time showing data in operation monitoring subsystem disorderly.Therefore, in the embodiment shown in fig. 6, for the exchange of the time synchronized message in 3,4 and No. 8 units, the periodicity time synchronized message of the time server of No. 3 machine non-core level DCS sends to No. 8 machine non-core level DCS, and the time synchronized message of No. 8 machine non-core level DCS does not allow to return No. 3 machine non-core level DCS, the periodicity time synchronized message of the time server of No. 4 machine non-core level DCS does not allow to send to No. 8 machine DCS, and the time message of No. 8 machine non-core level DCS does not allow to send No. 4 machine non-core level DCS to yet.
3) the third situation: when the quantity of described unit is two, described Network Isolation filter module is according to the physical address in network message, realize the parallel communication of the automatic processor between the first autonomous control subsystem, and stop the Cross talk of the automatic processor between the first autonomous control subsystem.Such as, in the embodiment shown in fig. 6,3, the AP of signal exchange is had between 4 and No. 8 units, its normal communication should not be limited, because the communication in autonomous control subsystem between redundancy AP only may exist parallel, and Cross talk can not be there is, such as there is signal exchange between redundancy AP first and redundancy AP second, the communication link of actual capabilities is the A side of AP first and the A side of AP second, both-way communication is carried out in the B side of AP first and the B side of AP second, and the A side of AP first and the B side of AP second, or there is not communication between the B side of AP first and the A side of AP second.
When implementing to install the measure of Network Isolation filter module additional, comprehensively above-mentioned 3 points, have carried out corresponding setting to each Network Isolation filter module.In addition, preferably, wherein also have the function of some details to need to arrange when arranging, the communication link of such as each permission allow the network bandwidth that takies, like this, the potential link assignment corresponding bandwidth of Network Isolation filter module also for according to the number of signals in the network message allowing to forward being this Communications service.Therefore, reasonably arrange and isolation effect can be made more obvious, and ensure high efficiency and the stability of network exchange.
In addition, replace or increase OSM of new generation, such as, in the embodiment shown in fig. 6, for 3, No. 4 machines, needing respectively, on existing network basis, to change and add the switch of a new generation of a small amount of Siemens.In PlantBus, use has said function, but that OSM of the existing responsible loop network Redundancy Management of ScalanceX204-2 switch replacement that algorithm is more advanced, more powerful, in 5 TrainBus, need to increase a ScalanceX204-2 switch respectively, and the loop network Redundancy Management function be responsible for by existing OSM is transferred on this switch increased.
