BIM-based GIM digital model modeling method for power transmission and transformation project

Abstract

The invention discloses a BIM-based GIM digital model modeling method for power transmission and transformation engineering. The method comprises the following steps of S110, digital engineering design; step S120, establishing a GIM: establishing the GIM; the digital engineering design in the step S110 is used as the basis; establishing a complete power transmission and transformation project information flow, taking composition elements in a power transmission and transformation project as entry points, analyzing project design data, carding common points among platforms in a project construction stage, and promoting one-time entry and repeated use of information data on the basis of GIM (Geographic Information Model) so as to construct a visual GIM with a full life cycle; and S130, constructing an information sharing platform. The method has the advantages that by means of a geographic information system, composition elements of the power transmission and transformation project are digitized, an information model serves as a carrier, information of each element of the power transmission and transformation project in the whole life cycle is integrated, and therefore efficient, accurate and comprehensive application of the information is achieved.

Description

technical field [0001] The invention relates to the technical field of modeling methods for power transmission and transformation projects, in particular to a BIM-based GIM digital model modeling method for power transmission and transformation projects. Background technique [0002] The integration of "power flow, information flow and business flow" is the basis for realizing the construction of smart grid, and the construction of information flow is the basic way to realize the smart grid. One of the keys to informatization is to carry out in-depth, multi-parameter fusion and collaborative processing of various information resources to provide detailed engineering information for each stage of project planning, design, production and operation. Establishing an information model is an effective means of information sharing. The existing information models of power transmission and transformation projects are mostly aimed at the operation stage of the power grid, and there i...

Problems solved by technology

At present, the status quo of power transmission and transformation projects is that each stage is self-contained, and each system has common requirements for engineering information. However, due to different business divisions and platform construction, information is divided into isolated islands, and information sharing cannot be realized; resulting in Repeated entry of the same type of information in the system not only increases a lot of work, but also reduces the accuracy of engineering information
