Table 2 double measurement and control principal and subordinate signal pair relationhip table
The parameter of setting device, principal and subordinate's signal pair relationhip carry out in the database caches module.
Database is used to store the parameter of (1) the double measurement and control master and slave devices pair relationhip table setting that sets, the parameter that (2) double measurement and control principal and subordinate signal pair relationhip table is provided with.
When the database configuration tool model reads, revises parameter that the double measurement and control master and slave devices pair relationhip of lane database is provided with, parameter that double measurement and control principal and subordinate signal pair relationhip is provided with; Earlier data of database (parameter) is extracted in the data cache module; Setting, modification that database is not preserved all are in data cache module, to carry out; Directly the data in the database are not provided with, revise; Being kept at of database selected in the database configuration tool model to preserve just to preserve afterwards, preserve and can the data in the data cache module (parameter) content be saved in the database.
When real-time data base RTDB module starts; Be kept at the parameter that the master and slave devices pair relationhip in the database is provided with, the parameter that principal and subordinate's signal pair relationhip is provided with what engineering staff or operation operator on duty set; Extract wherein initial information (being initialised in the shared drive wherein) as master and slave devices; In the running; Receive and the last master and slave devices data of sending of real-time update (refreshing) SCADA (remote signalling, remote measurement, distant arteries and veins), receive engineering staff or operation operator on duty order, receive the warning information of double measurement and control master and slave devices handover module automatic switchover master and slave devices through the change master and slave devices operation of client computer input; The data that renewal receives, operation and switching real time information send to client computer HMI module.
SCADA receives the data that master and slave devices is served, and is used for the master and slave devices data of updating real-time database.The master slave relation order of the manual switching double measurement and control device of subscribing client is sent to double measurement and control master and slave devices handover module, is used for the master slave relation of switch dual measure and control device.Receive the switching alarm information and the inconsistent warning information of signal of double measurement and control master and slave devices handover module, form corresponding remote signalling variation and sequence of events recording, send to client computer and dynamically show.
Client computer HMI module is a human-computer interface module, and the data of receiving real-time data storehouse RTDB, operation and switching real time information are obtained remote signalling variation and sequence of events recording from data acquisition and supervisor control SCADA, and enterprising action attitude shows at the interface.Simultaneously, engineering staff or operation operator on duty's operational order is imported through this module.When the operation operator on duty need carry out the master slave mode of manual switching double measurement and control device, through HMI input switching command, HMI was sent to the SCADA module with switching command.After the SCADA module received the HMI order, notice double measurement and control master and slave devices handover module was accomplished the switching to double measurement and control device principal and subordinate by double measurement and control master and slave devices handover module.
Double measurement and control master and slave devices handover module receives the manual switching double measurement and control device principal and subordinate switching command that SCADA forwards, and accomplishes double measurement and control device principal and subordinate and switches.Operation conditions according to double measurement and control device among the real-time data base RTDB; And the switch logic condition that is stored in double measurement and control device principal and subordinate handover module is judged; In real time double measurement and control device master slave relation is switched; Revise the master slave mode information among the real-time data base RTDB, and handover information is sent to data acquisition and supervisor control SCADA.After the master slave relation of manual work or automatic switchover double measurement and control device, the main device sequence number ID of the double measurement and control master and slave devices pair relationhip table in the real-time data base and the primary sequence ID in the double measurement and control principal and subordinate signal pair relationhip table are made amendment.
Master's measure and control device is as primary data source during the operation of double measurement and control master and slave devices, and the data of sending on the main measure and control device are as master data.When one of following switch logic condition appears in main measure and control device, will switch to main measure and control device from measure and control device, simultaneously main measure and control device is switched to from measure and control device.The switch logic condition is: 1. main measure and control device dead electricity, 2. main measure and control device and SCADA communication packet are made mistakes, and mess code occurs, important self-check of device 3. occurs and make mistakes, and comprise that the CPU self check makes mistakes, 4. main measure and control device maintenance.
The information that double measurement and control master and slave devices handover module is gathered real-time data base in real time; According to the switching condition that is stored in double measurement and control master and slave devices handover module; Detect the operation conditions of the measure and control device in the real-time data base, according to the master slave relation of measure and control device operation conditions decision switch dual measure and control device.Operation conditions comprises whether the communication of SCADA and measure and control device is normal, and whether measure and control device dead electricity, and whether measure and control device self check occurs is made mistakes, and whether measure and control device is in inspecting state, and whether measure and control device is responding control operation.
SCADA and measure and control device communication are masked as the network service that given duration do not occur normally and interrupt.Given duration is 60 to 120 seconds.
Whether measure and control device is in inspecting state, judges that through the remote signalling of inspection measure and control device the remote signalling value of giving the maintenance flag bit of SCADA on the measure and control device is 1, is inspecting state, and 0 is non-inspecting state.The user is set to 1 at the inspecting state of measure and control device measure and control device during maintenance, and the remote signalling value of giving the maintenance flag bit of SCADA on the measure and control device will be 1.
Double measurement and control master and slave devices handover module detects main device and SCADA when communication failure occurring, be in inspecting state or the self check error message occurring, checks simultaneously whether reserve arrangement normally, is not in inspecting state with the SCADA communication and self-check of device is made mistakes.If satisfy above condition simultaneously, pick up counting, through a time-delay process, do not change this state yet, then current main device is switched to from device, and will switch to main device from device, the signal of the main device after will switching simultaneously is as main signal.
Double measurement and control master and slave devices handover module checks simultaneously whether the double measurement and control device is consistent to the instantaneous value of the remote signals of primary equipment.If what certain primary equipment was corresponding begins inconsistent from the instantaneous value of the double signal of principal and subordinate's measure and control device from certain respectively constantly; Then pick up counting; Do not recover consistent yet through a time-delay process; Then double measurement and control master and slave devices handover module can produce an inconsistent alarm of signal, passes to client computer through the SCADA module, and gives operations staff on duty through interface display.
As shown in Figure 3, real-time data base receives main measure and control device 1 respectively and from the real time data of measure and control device 2 and carry out real-time update through SCADA.Confirm the signal source of main measure and control device according to double measurement and control master and slave devices pair relationhip table as primary equipment.
As shown in Figure 4, change intelligent substation redundant data treatment system of the present invention is switched principal and subordinate's measure and control device, may further comprise the steps:
One, the real time data library module is confirmed measure and control device pair relationhip and master slave relation through double measurement and control master and slave devices pair relationhip table.
Two, through double measurement and control principal and subordinate signal pair relationhip table, confirm measurement and control signal pair relationhip and master slave relation.
Three, the double data of principal and subordinate's measure and control device all are sent to SCADA.
Four, supervisory control system is with the data of the main signal of primary data source device in the real-time data base data value signal as primary equipment.
Five, main plant failure maintenance or communication failure are normal from installing, and the current time supervisory control system is not being carried out guidance command, is not operating five anti-simulated operations, do not had then to satisfy switching condition just in the executive program operation.Double measurement and control master and slave devices handover module changes the main device sequence number ID in the double measurement and control master and slave devices pair relationhip table, changes the primary sequence ID in the double measurement and control principal and subordinate signal pair relationhip table simultaneously, realizes the switching of master and slave devices and principal and subordinate's signal.
During the corresponding separately remote control of double measurement and control signal, search remotely-controlled object according to current major state remote signalling.Primary equipment has only a remote-control channel, is furnished with simultaneously under the situation of two state remote signalling, through signal pair relationhip table, remotely-controlled object and current major state remote signalling is dynamically associated.
Usually electric substation automation system all is based on the forms data source to the monitoring of primary equipment and control, the uniqueness of primary equipment information refer to certain constantly four distant signal values of primary equipment have only only portion.Suppose that the double measurement and control device is respectively device A and device B, current primary data source device is A, needs handle assembly B to switch to main device now.Detailed process is following:
1) searches article one record of double measurement and control principal and subordinate signal pair relationhip table; If ID is consistent with the ID of double measurement and control master and slave devices pair relationhip table for the pairing of the double measurement and control device of this record identification; Whether then judge main signal in the record from device A, from signal whether from device B.If, then change the ID of main signal, make it equal ID from signal, change principal and subordinate's signal with this.Finish if the ID of the double measurement and control device of this record identification pairing ID and current double measurement and control master and slave devices pair relationhip table is inconsistent, judgement is unsuccessful or change principal and subordinate's signal relation; All continue to use the same method and check next bar record, up to the last item record of remote signalling pair relationhip table.
2) the main device ID of the double measurement and control device pair relationhip table of modifier A, B correspondence makes its ID that equals device B, changes the master slave relation of double measurement and control device with this.
In the actual moving process; Even preserve two sets of data signals of two measure and control devices in the real-time data base simultaneously, but the corresponding signal of primary equipment all picks up from current primary data source device, has guaranteed any moment; The signal that primary equipment is corresponding has only portion, the uniqueness of primary equipment signal.
As shown in Figure 5, change intelligent substation redundant data treatment system of the present invention is obtained main signal, may further comprise the steps:
When one, SCADA or HMI need obtain this signal value through the signal ID of certain primary equipment; According to certain given concrete signal ID; From the double measurement and control principal and subordinate signal pair relationhip table of real-time data base, obtain this signal pointer (field identification),, then finish if obtain unsuccessfully.
If two obtain success, this signal pointer is designated as P.
Three, SCADA or HMI judge that this signal is the double measurement and control signal, if, then travel through double measurement and control principal and subordinate signal pair relationhip table, inquire about corresponding record, judge that this signal is a main signal; If not, then finish, directly return P.
Four, SCADA or HMI obtain main signal ID, are designated as MasterID, from real-time data base, obtain the corresponding signal of MasterID once more, and return this signal.
As shown in Figure 6, if the information of the primary equipment that send on the double measurement and control device is inconsistent, behind delay time, provide alarm.In delay time, recover consistent, then do not alarm.
As shown in Figure 7, the double measurement and control unit state satisfies the condition of switching master slave relation, behind delay time, changes yet, and double measurement and control master and slave devices handover module is realized principal and subordinate's switching, and provides switching alarm.In delay time, recover consistent, then do not carry out the principal and subordinate and switch, and do not alarm.
