Wherein, 1 be monitoring system backstage lock modules, 2 be wall lock modules, 3 be electronic circuit lock modules, 4
It is terminal device for intelligent terminal, 5.
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, the detailed implementation method and specific operation process are given, 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, it is anti-with tradition five
System is compared, which is located in the monitoring system of Intelligent transformer station, respectively with the intelligent terminal of Intelligent transformer station 4
It is connected with terminal device 5, terminal device 5 includes switch, plug-in strip and the earthing knife-switch of Intelligent transformer station.Five-preventing system includes monitoring system
System backstage lock modules 1, wall lock modules 2 and electronic circuit lock modules 3, monitoring system backstage lock modules 1 are distinguished
With in monitoring system monitoring data library and electronic circuit lock modules 3 connect, wall lock modules 2 and intelligent terminal 4 connect
It connects, electronic circuit lock modules 3 are connect 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
Spend end romote controlled locking.Monitoring system backstage lock modules 1 are connect by SMV network with electronic circuit lock modules 3.Wall closes
Lock module 2 includes at least three wall measure and control device, and mutually indepedent between wall measure and control device, wall measure and control device is equal
It is connect respectively with intelligent terminal 4 and electronic circuit lock modules 3.Wall measure and control device passes through GOOSE network and intelligent terminal 4
It is connected with electronic circuit lock modules 3.
The interactive process of wall measure and control device and intelligent terminal 4 specifically:
21) wall measure and control device sends the request signal of 5 state acquisition of terminal device 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 5 state of terminal device that energy terminal 4 returns；
23) wall measure and control device carries out logic calculation according to the received GOOSE message of step 22), judges terminal device 5
Whether it is latched, if then entering step 24), if otherwise return step 21)；
24) wall measure and control device sends locking order to electronic circuit lock modules 3.
The locking in three levels has been implemented according to the five-preventing system that foregoing description is realized:
One, the romote controlled locking at the locking of monitoring system station level or remote monitoring end, dispatching terminal.Five is anti-as monitoring system
One subsystem of system, database and the unification of monitoring data library, it is seamless to be dissolved into monitoring system.Intelligent transformer station monitoring system
System includes operation ticket function, and all-graphic interface is easily operated, formulation operation order, simulation preview and remote control in monitoring system
It is all verified through five anti-subsystems when operation, programming operations.
Two, wall measure and control device is latched, and wall five-defence block is established in GOOSES mechanism, can on measure and control device
To realize in interval and the technology across interval latching logic, real-time is high.
Interval measure and control device carries out information exchange by GOOSE network with intelligent terminal 4.Intelligent terminal 4 acquires relevant
Switch, plug-in strip, earthing knife-switch state are sent by GOOSE message with the forms of broadcasting.Each interval measure and control device is configured according to logic to close
System, receives associated intelligent terminal 4GOOSE message, calculates this spacing devices operation logic, interrupts 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.
Three, 18 it is counter arrange regulation, when using computer supervisory control system, a distant place, local operation should all have and prevent from accidentally grasping
Make blocking function, therefore when for guillotine kind local operation, it is necessary to have complete latching logic, simplify electric blocking circuit
Under design principle, the locking on electronic circuit is preferably realized in such a way that measure and control device is outputed and is latched hard contact.In intelligent station mould
Under formula, separating brake, combined floodgate, unlock open three in the GOOSE message that measure and control device is sent comprising each control object are ordered, intelligence
Energy terminal 4 is converted into contact relationship after receiving the GOOSE message of measure and control device, and the control that locking contact is series at disconnecting link is returned
Lu Zhong, the operation for opening electric operating equipment control power supply.Therefore, under normal circumstances, plug-in strip operation is either remotely controlled
Still electric operating on the spot, all has 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, barring condition is the telemetry with on-off model and this interval in this GOOSE network, due to becoming
In power station between each voltage class GOOSE network and GOOSE network and SMV network it is mutually isolated, therefore barring condition cannot
Telemetering, the remote signals for adopting whole station can not allow virtual remote signal to participate in latching logic；The locking of monitoring system backstage is established in MMS
On the net, barring condition can be telemetering, the remote signals of whole station, while should also include the empty remote signals such as ground line.
