Problems solved by technology

[0002] The current transmission network model has formed a huge regional power grid model through model splicing technology, covering multiple voltage levels and various types of power grid equipment objects. The power supply network dispatching decision system uses it. The advantage is that the description granularity of this model is relatively fine, and it can Meeting the requirements of different application systems is very necessary for material management and production emergency repairs, but its disadvantages are: for the decision-making of transmission network scheduling operation, the granularity of the model is too detailed and large, which is not conducive to the overall macroscopic vision of transmission network operation decision-making and the establishment of local microscopic field of view and the simplification of analysis and calculation

Embodiment Construction

[0030] The preferred embodiments of the present invention will be described in detail below; it should be understood that the preferred embodiments are only for illustrating the present invention, rather than limiting the protection scope of the present invention.

[0031] The transmission network model view abstraction and compression method of the present invention divides the transmission network model abstraction into four layers, including the station layer, the switch layer, the contact layer and the user layer; the station layer expresses the relative positions between the stations, and the The connection layer is used to display the relationship between the substation and the feeder and between the feeder and the feeder. The switch layer is used to display the switch segment relationship inside the feeder. The user layer is further used to display the switch layer. Specific user location; the station layer has no topology, and the contact layer, switch layer and user la...

Abstract

The invention discloses an abstraction and compression method of a transmission network view model, which divides the abstraction of the transmission network view model into three categories, including voltage level categories, regional network categories, and contact relationship categories; the voltage level categories, regional network categories The local model of the power grid corresponding to the class and contact relationship class is obtained according to the compression algorithm, and the compression rules are: voltage level class: the equipment object of the selected voltage level is taken as a whole, the external objects are compressed to the boundary, and the boundary object and its external important channels are reserved; the area Slice network class: compress the outside to the boundary of the selected area object, retain the boundary object and its external important channels; contact relationship class: compress the outside to the boundary of the selected contact relationship object, retain the boundary object and its external important channels. The invention better integrates the requirements of the macroscopic and microscopic decision-making vision required for the operation decision-making of the transmission network to the abstract model corresponding to the logical view of the transmission network.

Description

technical field [0001] The invention relates to the field of data processing in power systems, in particular to an abstraction and compression method for a transmission network view model. Background technique [0002] The current transmission network model has formed a huge regional power grid model through model splicing technology, covering multiple voltage levels and various types of power grid equipment objects. The power supply network dispatching decision system uses it. The advantage is that the description granularity of this model is relatively fine, and it can Meeting the requirements of different application systems is very necessary for material management and production emergency repairs, but its disadvantages are: for the decision-making of transmission network scheduling operation, the granularity of the model is too detailed and large, which is not conducive to the overall macroscopic vision of transmission network operation decision-making And the establish...
