Abstract

The invention relates to the technical field of three-dimensional GIS systems, and discloses an application of a power distribution network model in a three-dimensional GIS system, which comprises the following steps: a power distribution network model is created and the power distribution network model is imported into the three-dimensional GIS system after constructing the power distribution network model, the three-dimensional GIS system adopts a UGX user-defined rendering data format and a UGT partitioning technology, a multi-level-of-detail model is originally constructed when a power distribution network model is triangulated, and an instantiation technology is adopted. According to the application of the power distribution network model in the three-dimensional GIS system, during triangularization of the power distribution network model, a multi-level-of-detail model is originally constructed, hierarchical storage can be carried out according to two surfaces, four surfaces, eight surfaces and sixteen surfaces in the model generation process of a curved surface, so that different grades can be generated in the model generation process; the invention can be observed by selecting different grades according to different graphics cards, so that the situation that the memory is too large, and jamming and collapsing occur in the using process is avoided.

Description

technical field [0001] The invention relates to the technical field of three-dimensional GIS systems, in particular to an application in a three-dimensional GIS system based on a distribution network model. Background technique [0002] In recent years, three-dimensional digital technology has gradually emerged, and various design companies are constantly improving design operation and maintenance methods, and have begun to try to apply three-dimensional digital tools. In the field of power transmission and transformation engineering design, three-dimensional digital exploration has been carried out and achieved certain results. So far, an application based on the distribution network model in the 3D GIS system has been developed. [0003] In the existing application of the distribution network model in the 3D GIS system, the forward 3D design of the distribution network field of 10kV and below has just started. , When there are multiple models, the freeze is not smooth. ...
