Accompanying drawing explanation
Fig. 1 is method flow diagram of the present invention.
Embodiment
The integrated graphic joining of adjusting in evaluation work in ，Yi Shengdi county is that example further illustrates the present invention below.As shown in Figure 1, a kind of graphic joining method that realizes electric network composition layering displaying, comprises the following steps:
Raw graphics data in S1, extraction constituent parts electric network model, converts thereof into CIM-G form, imports the computational data center of adjusting.Constituent parts is uploaded to primary server database by the raw graphics data in its electric network model by electric system Intranet, raw graphics data in constituent parts electric network model is read out from database, and convert CIM-G form to, then import the computational data center of adjusting.The graph data of constituent parts can be expressed the annexation between our unit's internal electric network structure and each plant stand.Graph data is changed according to unified standard format CIM-G, can guarantee versatility of the present invention, even if the computing system producer of adjusting that constituent parts adopts is different, by graphics data format, change, still can realize the graphic joining of the various computing systems of adjusting.CIM-G(Common Information Model Based Graphic Exchange Format) GIF(Graphic Interchange format) based on common information model.
Border plant stand in S2, identification constituent parts electric network model, splices the graph data of border plant stand, retains the enclose pattern data in constituent parts electric network model, forms complete the whole network graphical model.The identification principle of border plant stand is: if name identical two plant stands to belong to respectively different unit to be spliced electric network models, this plant stand is identified as to border plant stand.Graph data to border plant stand splices, according to following principle, carry out: if border plant stand belongs to respectively the electric network model of Liang Ge different stage unit, according to the high-pressure side graph data of this border plant stand in superior unit electric network model, set up the high-pressure side graphical model of this border plant stand, according to the medium/low pressure side graph data of this border plant stand in subordinate unit's electric network model, set up the medium/low pressure side graphical model of this border plant stand; If border plant stand belongs to respectively the electric network model of Liang Ge same levels unit, according to the graph data of this border plant stand in the scoping unit electric network model of this border plant stand, set up the graphical model of this border plant stand.According to above-mentioned splicing principle, finally form complete the whole network graphical model.For example, by each regional power grid model splicing to figure in provincial power network, be convenient to the graph data that each subordinate unit is checked by For Provincial Power Grid Corporation.
S3, the whole network graphical model having spliced is traveled through, according to electric pressure, find out zone boundary circuit as each interregional interconnection, be designated ground floor; The electric network wiring scheme that goes out each region according to the compass of competency information searching of equipment, is designated the second layer; According to power plant and substation's information, find out the station internal wiring figure of each plant stand, be designated the 3rd layer.The whole network graphical model is shown according to sign layering.
For example, take each city-level electrical network is base unit, according to electric pressure, searches all 220kV circuits both sides plant stand affiliated area, and when region is different, judgement circuit is zone boundary circuit, and ground floor is shown each interregional 220kV border circuit in provincial power network; Take administration company in city-level electrical network is base unit, and according to the administration company information of equipment in electric network model, the second layer is shown 110kV and the 35kV electrical network main wiring diagram of provincial power network main wiring diagram and the administration of each city-level electrical network; Show the inner concrete element of each plant stand and connected mode for the 3rd layer.The present invention has retained the full graphics of each level electric pressure, by layering, shows, has avoided the structure of a figure of the whole network graphical model, can clearly observe the hierarchical structure of electrical network and the contact between each layer of structure, improves the efficiency of adjusting and calculating.
The above embodiment is only that the preferred embodiment of the present invention is described; not scope of the present invention is limited; design under the prerequisite of spirit not departing from the present invention; various distortion and improvement that those of ordinary skills make technical scheme of the present invention, all should fall in the definite protection domain of claims of the present invention.
