Referring to Fig. 1, it is integrated guarantor's electric power system the first example structure schematic diagram of main distribution provided by the invention.As shown in Figure 1:
The integrated guarantor's electric power system of this main distribution comprises: dispatch automated system (EMS) 1, distribution automation system (DMS) 2 and video monitoring system 3.
Between above-mentioned each system, adopt Common Information Model (CIM) extensible markup language (XML) form to carry out grid model splicing between dispatch automated systems at different levels, the figure being undertaken between dispatch automated systems at different levels by scalable vector graphics (SVG) form is shared.
More specifically, the foundation of system model and figure be one not only loaded down with trivial details, and workload is worked greatly, so the foundation of model and the foundation of figure, can not do from basis, otherwise, can be because data volume be huge, workload is very big, and not only system Construction cycle stretch-out, and accuracy is also not easy the result ensureing.
So, the integrated guarantor's electric power system of main distribution that the embodiment of the present invention provides adopts collects dispatch automated system (EMS) 1 and ready-made model and the figure of distribution automation system (DMS) 2, by model splicing and graphic joining, form the mode that whole system comprises model and the figure of major network and distribution.Certainly the incremental processing that native system must supply a model, to reduce to greatest extent the maintenance workload of system.
Electric network model and figure that the integrated guarantor's electric power system of main distribution that the embodiment of the present invention provides is safeguarded for the multiplexing regional of having set up, reduce the workload of electric power safeguard automated system modeling and picture, the integrated guarantor's electric power system of main distribution need to realize multiple regional power grids in splicing and merging.The common information model (CIM) of IEC61970 standard carries out unified Modeling for dispatch automated systems at different levels to electrical network provides model specification, adopts CIM extensible markup language (XML) form and scalable vector graphics (SVG) form to realize grid model splicing and figure between dispatch automated systems at different levels and shares.
Further, for ensureing that merging the large electric network model forming can carry out the senior applied analyses such as network topology, state estimation, trend calculating, need to ensure the topological accuracy that each needs pooled model.Therefore, the integrated guarantor's electric power system of described main distribution, before each system grid model splicing, is carried out topological verification, checks and whether has the equipment connection of different electric pressures together.Whether the optional mode of this inspection is: the model information in border transformer station and main information source is compared, check consistent; Wherein, comprise the electric network model that T connects interconnection and integrate with in electric power safeguard automated system process, need to connect group technology and carry out the merging of T contact and amendment T and connect according to T the annexation of interconnection.
It should be noted that, article one, transmission line is powered from first transformer station to second transformer station, if also need to power to the third transformer station from first transformer station, for reducing investment, just in the middle of the transmission line of power supply, pick out a transmission line from first transformer station to second transformer station nearby, be fed to the third transformer station, this mode that picks out another circuit from main line is called " T connects interconnection " visually so, and this picks out a little and is just called as " T contact ".

Because the integrated guarantor's electric power system of main distribution need to realize merging and splicing to major network and electricity distribution network model, therefore, can not all after regional model changes, carry out each time the model modification of full dose, and should be the incremental update that carries out model for this regional model.The increment of model comprises the increment (device parameter) of the object such as plant stand, equipment, and the increment of equipment connecting relation.Because plant stand, equipment specification unified name, the difference of plant stand and equipment is processed relatively simple.Plant stand in new model (or equipment) and the plant stand of the same name (or equipment) in operational system are compared, check the situation that whether has increase, deletes or upgrade, and the plant stand to operational system (or equipment) is taked corresponding operation according to check result.
But for equipment connecting relation, owing to cannot the name of end points (Terminal) and tie point (Connectivity Node) being carried out to specification, and a regional model also cannot ensure that the name of end points or tie point remains unchanged before and after upgrading, therefore, in the time carrying out equipment connecting relation incremental update, need to the equipment connecting relation of model to be imported be tied on the equipment connecting relation of operational system according to the incidence relation between equipment, end points, tie point.For certain concrete equipment, annexation binding is bound the connecting terminals contact incidence relation of equipment of the same name in the connecting terminals contact incidence relation of this equipment in model to be imported and operational system exactly, finds out the corresponding tie point of tie point in model to be imported from operational system.Because the associated tie point of single-ended point device (as bus, Transformer Winding, shunt capacitor, shunt reactor, generator, load, grounding switch etc.) can be realized binding very clearly, therefore, will be from single-ended point device while carrying out annexation binding, and then binding one end has been identified the both-end point device (as switch, disconnecting link, circuit, series capacitor, series reactor etc.) of binding, repeated multiple timesly can complete all bindings.
After the equipment connecting relation binding that completes operational system and model to be imported, the integrated guarantor's electric power system of main distribution just can be carried out the incremental update of model, and the principle of renewal is the annexation that does not change bound object.
