Geographic information system applied to power system and method for improving display efficiency thereof

Abstract

The embodiment of the invention provides a geographic information system applied to a power system and a method for improving display efficiency thereof. The system comprises a data unit, an interface engine unit, a power grid data model unit, a system component unit, a map layer management component and an application component unit, wherein the data unit stores two-dimensional geospatial data and attribute information of a power grid equipment object; the interface engine unit provides an interface display control and a message mechanism and is interacted with a user; the power grid data model unit is used for accessing the data unit to establish and maintain a power grid equipment model and performing network analysis on the power grid equipment model; the system component unit is usedfor calling services of the interface engine unit and the power grid data model unit and implementing display of a map and operation of the map, wherein the services comprise map display and component operation; the map layer management component is used for providing a management tool to support the display of the map; and the application component unit comprises a power grid modeling component and is used for calling the service of the power grid data model unit through the system component unit to perform modeling on power grid equipment. The system realizes function customization and flexible expansion.

Description

technical field [0001] The invention relates to a geographic information system (GIS, Geographic Information System), in particular to a geographic information system applied to a power system and a method for improving its display efficiency. Background technique [0002] In the implementation process of the company's power transmission and distribution GIS project for many years, there are difficulties such as long implementation period, high cost, and difficulty in effectively controlling system stability, performance and graphic display effects. From a technical point of view, the existing power transmission and distribution GIS system is already very complex, and the coupling between modules is very tight. In the system centered on GIS graphics, the effect and efficiency of graphic display are very important. The previous systems have shortcomings such as poor graphic display quality, slow operation response speed, and cumbersome editing of graphic data. Moreover, in t...
