Observing and controlling function modifications need be considered between station, interior two kinds of demands of standing, and in standing, demand is again because of different in compartment and interval.Refer between standing between transformer station and scheduling station, between standing, information point table only expands newly-added information point.Conversion and the transmission of information between station are responsible in communication network shutdown.Switch point process layer and 2 stages of wall in standing, process layer retrofit work comprises the access of process-level network structure, merge cells and intelligent terminal, and wall retrofit work comprises the switching of wall network struction, new and old measure and control device.The switching of new and old measure and control device is shut down by communication network and is realized, and reduces the disturbance of switching mainly through improving the similarity of new and old measure and control device.In interval, Installation Modes on the spot taked usually by merge cells and intelligent terminal, or installs concentratedly near secondary cable distributing cabinet, and installing space can meet substantially, and process layer transformation can not have a power failure thus, and global precedence effect is transformed in wall.Wall network struction entirety can complete when not having a power failure.
New and old measure and control device switches then to be needed progressively to transform by interval, because measure and control device need be installed on cell or master-control room, faces the difficulty that space is extremely limited.The connection locking of old station improvement project intermediate compartment measure and control device can only overall uniting and adjustment in factory, because the transformation of substation field interval is asynchronous, do not possess the condition of uniting and adjustment.Existing intelligent monitoring remodeling method as shown in Figure 1.Conventional measure and control device screen needs to tear cable dress optical cable open, and be limited to the space of measure and control device screen, transformation process cannot disposablely complete.
In view of this, the present inventor studies this, and develop the application of a kind of cluster TT&C system in the improvement project of intelligent substation old station specially, this case produces thus.
Summary of the invention
The object of this invention is to provide the application of a kind of cluster TT&C system in the improvement project of intelligent substation old station, solve because measure and control device installing space is limited in the improvement project of old station, and the transformation link caused is complicated, the problem that workload is large.
The application of cluster TT&C system in the improvement project of intelligent substation old station, comprises the steps:
Step 1, telecontrol communication machine replace with gateway machine;
Step 2, structure three-layer network: network struction comprises process-level network structure, wall network struction and station level network struction, to the effect that fiber cable laying and switchboard unit network, and optical fiber is to point and mark number;
Step 3, wall are transformed: install, debug merge cells and intelligent measuring and control device, and shut down by intelligent measuring and control device Access Network;
After the transformation of step 4, wall, remove conventional measure and control device screen, intelligent measuring and control device screen is installed; The on-the-spot disposable installation of optical cable, exits cluster measure and control device, drops into intelligent measuring and control device.
The application of cluster TT&C system of the present invention in the improvement project of intelligent substation old station, when wall is transformed, has the advantages such as installing space is little, retrofit work amount is little, simple operation.
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Accompanying drawing explanation

Fig. 2 is the reconstruction flow figure of the present embodiment;
Fig. 3 is the station level modification scheme figure of the present embodiment;
Fig. 4 is the observing and controlling screen modification scheme figure of the present embodiment.
Embodiment
The intellectualized reconstruction work of conventional substation is divided into network struction, process layer transformation, station level transformation and wall transformation four-stage.For convenience wall transformation of the present invention is called that cluster observing and controlling is transformed, is different from the transformation of existing intelligent monitoring.The measure and control device that intelligent monitoring transformation uses is called intelligent measuring and control device, and the measure and control device that cluster observing and controlling transformation uses is called cluster measure and control device.Intelligent monitoring remodeling method and cluster observing and controlling remodeling method are similar in network struction, process layer transformation, station level transformation link.
As shown in Figure 2, the application of a kind of cluster TT&C system in the improvement project of intelligent substation old station, comprises the steps:
Step 1, telecontrol communication machine replace with gateway machine;
Step 2, structure three-layer network: network struction comprises process-level network structure, wall network struction and station level network struction, the network insertion work of equipment belongs to the process layer transformation of correspondence, wall transformation and station level retrofit work.The to the effect that fiber cable laying of network struction work and switchboard unit network, and optical fiber is to point and mark number;
Step 3, wall are transformed: install, debug merge cells and intelligent measuring and control device, and shut down by intelligent measuring and control device Access Network;
After the transformation of step 4, wall, remove conventional measure and control device screen, intelligent measuring and control device screen is installed; The on-the-spot disposable installation of optical cable, exits cluster measure and control device, drops into intelligent measuring and control device.
Network struction comprises process-level network structure, wall network struction and station level network struction three some work, and process layer transformation needs to stop transport by interval, installs merge cells and intelligent terminal, and by merge cells and intelligent terminal access procedure layer network.Conventional substation does not have process layer smart machine, and merge cells and intelligent terminal adopt mounting means on the spot usually, as being installed on the convergence control cabinet of GIS, or Outdoor Terminal Case, very little to interior space demand.
Station level transformation needs to install monitoring backstage and gateway machine, and transformation process as shown in Figure 3.Gateway machine and telecontrol communication machine need to run simultaneously, and gateway machine acts on behalf of original telecontrol communication machine and dispatching communication.After the transformation of full station terminates, gateway machine will replace original telecontrol communication machine completely.Owing to being progressively to have a power failure transformation by interval, certainly exist the phenomenon that conventional measure and control device and intelligent measuring and control device run simultaneously, this just requires that gateway machine treats conventional measure and control device and intelligent measuring and control device with a certain discrimination.For conventional measure and control device, gateway machine accepts dispatch command and by transferring order telecontrol communication machine, gateway machine accesses telecontrol communication machine data, and is dispatched by data retransmission.For intelligent measuring and control device, the instruction of gateway machine receiving scheduling, forwards intelligent measuring and control device; Gateway machine receives intelligent measuring and control device data, forwards scheduling after merging with telecontrol communication machine data.
Wall transformation adopts cluster observing and controlling remodeling method, and transformation process as shown in Figure 4.Cluster measure and control device screen is installed, in screen, 2 cluster measure and control devices is installed, corresponding to 30 intelligent measuring and control devices (being equivalent to 5 measure and control device screens).For transformation interval, exit conventional measure and control device, drop into virtual measurement and control device, and virtual measurement and control device Access Network is shut down.The optical cable installment work of cluster measure and control device screen, scene is disposable to complete.After transformation terminates, remove conventional measure and control device screen, intelligent measuring and control device screen is installed; Optical cable installment work, scene is disposable to complete.Exit cluster measure and control device, drop into intelligent measuring and control device.
