Brief description of the drawings
Fig. 1 is the structural representation of the five-preventing system for Intelligent transformer station；
Wherein, 1 is monitoring system backstage lock modules, and 2 is wall lock modules, and 3 is electronic loop lock modules, 4
It is intelligent terminal, 5 is terminal device.
Specific embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.The present embodiment is with technical solution of the present invention
Premised on implemented, give detailed implementation method and specific operating process, but protection scope of the present invention is not limited to
Following embodiments.
It is as shown in Figure 1 a kind of five-preventing system for Intelligent transformer station provided in the present embodiment, prevents with tradition five
System is compared, and the five-preventing system is located in the monitoring system of Intelligent transformer station, respectively with the intelligent terminal 4 of Intelligent transformer station
Connected with terminal device 5, terminal device 5 includes switch, plug-in strip and the ground knife of Intelligent transformer station.Five-preventing system includes that monitoring is
System backstage lock modules 1, wall lock modules 2 and electronic loop lock modules 3, monitoring system backstage lock modules 1 are distinguished
It is connected with the monitoring data storehouse in monitoring system and electronic loop lock modules 3, wall lock modules 2 connect with intelligent terminal 4
Connect, electronic loop lock modules 3 are connected with terminal device 5.
Wherein, monitoring system backstage lock modules 1 include monitoring system station romote controlled locking, remote monitoring romote controlled locking or tune
Degree end romote controlled locking.Monitoring system backstage lock modules 1 are connected by SMV networks with electronic loop lock modules 3.Wall is closed
Lock module 2 includes at least 3 wall measure and control devices, and separate between wall measure and control device, wall measure and control device is equal
It is connected with intelligent terminal 4 and electronic loop lock modules 3 respectively.Wall measure and control device is by GOOSE network and intelligent terminal 4
Connected with electronic loop lock modules 3.
Wall measure and control device is specially with the interaction of intelligent terminal 4：
21) wall measure and control device sends the request signal of the state acquisition of terminal device 5 to intelligent terminal 4；
22) wall measure and control device judges whether GOOSE network interrupts, if then entering step 24), if otherwise receiving intelligence
The GOOSE message comprising the state of terminal device 5 that energy terminal 4 is returned；
23) wall measure and control device is according to step 22) receive GOOSE message carry out logical calculated, judge terminal device 5
Whether need to carry out locking, if then entering step 24), if otherwise return to step 21)；
24) wall measure and control device sends locking order to electronic loop lock modules 3.
The five-preventing system realized according to foregoing description has implemented the locking in three aspects：
First, the locking of monitoring system station level, or remote monitoring end, the romote controlled locking of dispatching terminal.Five is anti-as monitoring system
One subsystem of system, its database and monitoring data storehouse are unified, seamless to be dissolved into monitoring system.Intelligent transformer station monitoring system
System includes operation ticket function, all-graphic interface, it is easy to operate, formulation operation order, simulation preview and remote control in monitoring system
All verified through five anti-subsystems when operation, programming operations.
2nd, wall measure and control device locking, wall five-defence block is set up in GOOSES mechanism, can on measure and control device
To realize that, in interval and across the technology of interval latching logic, real-time is high.
Interval measure and control device carries out information exchange with intelligent terminal 4 by GOOSE network.Intelligent terminal 4 gathers correlation
Switch, plug-in strip, knife-like state, by GOOSE message with the forms of broadcasting send.Each interval measure and control device is configured according to logic and closed
System, receives associated intelligent terminal 4GOOSE messages, and this spacing devices operation logic is calculated, and is interrupted in GOOSE
In the case of, the operation of relevant device will be blocked.Without lateral ties, other measure and control device failures do not influence each interval measure and control device
The logic blocking of this interval measure and control device.
3rd, 18 it is counter arrange regulation, during using computer supervisory control system, a distant place, local operation all should possess to be prevented from grasping by mistake
Make blocking function, therefore during for guillotine kind local operation, it is necessary to there is complete latching logic, simplifying electric blocking loop
Under design principle, the locking on electronic loop is preferably realized by the way of measure and control device outputs the hard contact of locking.In intelligent station mould
Under formula, the separating brake comprising each control object, combined floodgate, open three orders of unblock, intelligence in the GOOSE message that measure and control device sends
Energy terminal 4 is converted into contact relation after the GOOSE message for receiving measure and control device, and the control that locking contact is series at disconnecting link is returned
Lu Zhong, the operational control power supply for opening electric operating equipment.Therefore, under normal circumstances, plug-in strip operation either remote control
Still electric operating on the spot, is respectively provided with perfect logic blocking.
The locking of monitoring system backstage and wall locking are logically consistent substantially.Foundation is spaced on the net in GOOSE
Layer observing and controlling locking, its barring condition be with the on-off model and the telemetry at this interval in this GOOSE network, due to change
In power station between each voltage class GOOSE network and GOOSE network and SMV networks it is mutually isolated, therefore barring condition can not
Remote measurement, the remote signals of whole station are adopted, Virtual remote signal can not be allowed to participate in latching logic；The locking of monitoring system backstage is set up in MMS
On the net, its barring condition can be whole station remote measurement, remote signals, while should also including ground wire etc. void remote signals.
