Embodiment Construction

[0025] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0026] In the embodiment of the present invention, the CIM standard definition defined by IEC 61970 / 61968 is the logical model (Physical Model) of the power grid topology, and the physical model stored in the relational database is defined by each specific implementation and is not specified in the CIM standard. Before explaining that the grid topology of the present invention is stored in the physical model of the relational database, the grid topology logic model of the CIM standard is briefly introduced, referring to figure 2 It is the schematic diagram of the power grid topology of the CIM standard. The logic model of the power grid topology of the CIM standard is composed of the conducting equipment (Conduc...

Abstract

The invention is suitable for the field of power grid geographic information systems and provides a physical storage and optimization method of power grid topology in a relational database, and the method mainly comprises the following steps: dividing equipment participating in the power grid topology into a Segment and a Gadget, and using the Gadget and the Segment to define the topological connection relation among the equipment; optimizing the storage way of the Segment; increasing a Path object and a model for constituting the composition relation of the Segment in the power grid topology; adopting HyperGadget and the management way of connection inside and outside a station to realize a layered topological model and circuit topological perforation; and adopting a database table based on the universal relational database for realizing physical storage of power grid topological objects. By adopting the method, the physical storage of the power grid topology in the universal relational database is realized on the premise that a logical model accord with the topological standard of a CIM (common information model) power grid, and the more optimization work can be performed, aiming at the application characteristics of a GIS (geographic information system) of the power grid.

Description

technical field [0001] The invention belongs to the field of grid geographic information, in particular to a method for physically storing and optimizing grid topology in a relational database. Background technique [0002] Power grid geographic information system (grid GIS system) is a professional information system that uses geographic information (GIS) technology to manage power transmission, power transformation, power distribution and low-voltage power grids. It is mainly used in provinces, prefectures, and counties under the State Grid and China Southern Power Grid. Power supply bureaus, power bureaus or power companies at all levels realize business functions such as graphics management, file maintenance, automatic graphing and topology analysis of transmission, transformation, distribution, and low-voltage power grids. [0003] The power grid GIS system has similarities with the general geographic information system (general GIS system), but there are also very big ...
