Embodiment Construction

[0020] The ultra-large-scale low-voltage data processing method is set up in the power grid GIS architecture with centralized deployment of the server and decentralized application of the client. Geographic Information System (GIS, Geographic Information System) is a comprehensive subject that combines geography and cartography, remote sensing and computer science. It has been widely used in different fields and is used for input, storage, query, analysis and display. The computer system of geographic data, with the development of GIS, is also called "Geographic Information Science" (Geographic Information Science). In recent years, GIS is also called "Geographic Information Service". GIS is a computer-based tool for the analysis and processing of spatial information (in short, the mapping and analysis of phenomena and events that exist on Earth). GIS technology integrates the unique visual effects and geographic analysis functions of maps with general database operations (suc...

Abstract

The invention aims at overcoming the prejudice of the prior art, and designs a scientific ultra-large-scale low-voltage data processing method, wherein the existing network architecture is utilized, thus data storage and retrieval are much facilitated, and abnormal data therein can be analysed in time; the missing of data is also avoided during the whole system running process. The technical scheme adopted by the ultra-large-scale low-voltage data processing method disclosed by the invention is as follows: the ultra-large-scale low-voltage data processing method comprises the steps of storing the whole database in a single file on a host machine, creating a cache for low-voltage grid data in a memory according to the belonged running unit of operating personnel, forming the subset of the whole low-voltage grid, and the like. The ultra-large-scale low-voltage data processing method disclosed by the invention belongs to an improvement on the traditional technology; with the adoption of the ultra-large-scale low-voltage data processing method disclosed by the invention, the minimum calculation unit can be effectively set; due to the manner of setting a spatial grid index and combining with an R-tree index, the efficiency of indexing is greatly increased and the calculation amount is reduced.

Description

technical field [0001] The invention relates to a data processing method, in particular to a low-voltage power grid data processing method. technical background [0002] According to the overall plan of the power company, it is required to extend from the distribution transformer to the low-voltage power grid on the basis of the existing distribution network GIS system, and establish a complete "substation-10kV line-distribution transformer-low-voltage line-customer" on a unified geographic information platform The full-voltage, integrated business and distribution grid model establishes a unified and standardized topological connection relationship between grid models at all levels, and adopts hierarchical analysis and hierarchical display methods to achieve full-voltage grid model integrity, unified data, and clear display , easy operation and construction goals, laying the foundation for the further development of marketing business and distribution network business in th...
