Embodiment Construction

[0039] In order to better understand the technical content of the present invention, specific embodiments are provided below, and the present invention is further described in conjunction with the accompanying drawings.

[0040] see figure 1 , figure 2 , image 3 , Figure 4 , a method for constructing a temporal model of electric power GIS based on a ground state correction model, comprising the following steps:

[0041] S1. From the existing database grid GIS user reads the specified zoning geographically and synchronizes the main version chain equipment along the layout and station wiring diagram into the temporal GIS database.

[0042] Specifically, from the existing database grid GIS user reads the specified zoning geography along the main version chain of layout and station wiring diagram and synchronizes the equipment to the temporal GIS database. The incremental update is synchronized in the way of days + 1. The synchronization process requires Judging whether the...

Abstract

The present invention provides a method for constructing a power GIS temporal model based on a ground state correction model. The method comprises the following steps that: S1: a user reads a specified partition geographic layout from an existing database power grid GIS, and synchronizing the specified partition geographic layout and a main version chain device of a primary connection diagram in the station into a temporal GIS library; S2, the variation of a power grid model along the time axis is divided into several continuous state sections by using the temporal GIS, so that the temporalization of the grid model is realized; S3, a day+1 manner is used to perform incremental updating in the state sections; and S4, the updated data is saved into a power grid model data table. According tothe method for constructing a power GIS temporal model based on a ground state correction model provided by the present invention, the historical data storage and retrieval efficiency can be solved,and redundant data can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of electric power GIS, in particular to a method for constructing a temporal model of electric power GIS based on a ground state correction model. Background technique [0002] With the increasing scale of the power grid, the development and change of the power grid is accelerating. How to accurately and intuitively display the development and changes of the power grid scale and wiring, and predict the law of future power grid planning and construction. There has been a lack of suitable software platform support in the power industry. [0003] The traditional GIS system can only reflect the state of the power grid in the recent period, and lacks effective support in terms of historical information tracing and future power grid development prediction. Temporal GIS uses the direct relationship between the power grid model and the time model, and integrates temporal semantic SQL technology to realize fast quer...
