Country's dispatch automated system is mostly integrated system at present, during topological structure of electric building, is used
Primary connection figure mode corresponding with physical device model generates node serial number.Firstly, in the drawing process of primary connection figure,
Graphic editor forms and distributes " the initial point number " of each terminal, combines power plant and substation's information belonging to current Graphics later, currently sets
Standby voltage class information generates the final node serial number of terminal and saves into model information, opens up to complete grid equipment
Flutter the building of structure.However, going deep into the smart grid process of integration, saving ground integral system gradually becomes more universal
Power network dispatching system framework mode, in such systems, save adjust plant stand, adjust plant stand there is significant portion of coincidence, together
Equipment in one plant stand is repeated there is also a large amount of.According to the mode of existing central system, saves and harmonically adjust model used
Respectively maintenance, needs to establish a set of region within the jurisdiction electric network model and station wiring diagram respectively, interconnects mechanism based on existing province
And technical support, it is difficult to realize on-demand dynamically shared, in synchronous and network-wide basis the topological structure building for saving ground model, this
Point not only causes a large amount of repetition and safeguards that wasting manpower and material resources, each functional application dispatched with also preventing province is from obtaining enough
Information, topological structure process can not get rid of the dependence to network, at the same there is no to electric network composition originally " layering and zoning "
Feature is efficiently used, and interact, formed an integrated bulk power grid bottleneck with further enhancing province is become.
Summary of the invention
In view of the deficienciess of the prior art, it is an object of the present invention to provide a kind of provincial power grid device topology distributions
