Web GIS (geographical information system)-based comprehensive alarm display method

Abstract

The invention discloses a Web GIS (geographical information system)-based comprehensive alarm display method. The method comprises the following steps: importing the tower and plant station data with geographic information to a GIS spatial database, and connecting the towers in the same circuit to form a circuit based on the sequence of tower numbers according to the circuit and the tower numbers of the towers; importing the information in the GIS spatial database; calling a display interface provided by a GIS service platform; performing layered drawing on power equipment on a Web browser according to equipment types and voltage grades to form a comprehensive display page; associating a service sub-system with the comprehensive display page to organize all comprehensive alarms according to the equipment, and organizing all comprehensive alarms associated with the same equipment together to form an comprehensive alarm array of the equipment. By adopting the Web GIS-based comprehensive alarm display method, the alarm information of sub-systems such as a power transmission and transformation monitoring system, a power grid scheduling automation system and a prudential system is integrated, and the alarms are classified, so that the comprehensive alarm information of the power grid can be learnt more visually, intuitively and thoroughly.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a WebGIS-based comprehensive alarm presentation method. Background technique [0002] With the rapid growth of the scale of the power grid, the AC and DC lines in the Southern Power Grid are intricate, the power plants and substations are dotted, the number of power equipment is huge, and the information of the power grid is constantly changing. This has put forward higher requirements for the dispatcher's global control ability and fine-grained control ability, and the traditional power graphics system has been difficult to meet this requirement. From the actual situation, all kinds of information of the power grid are closely related to the spatial geographical environment. Therefore, relying on the geographic information system (GIS) to manage power grid resources, improve the level of panoramic information display, and speed up information acquisition and circulation ca...

AI Technical Summary

Problems solved by technology

[0004] Alarms are the most critical, sensitive, and most worthy of attention and analysis in the grid automation system. Traditional grid automation systems often use lists, curves, etc. to list all alarm information when displaying alarms. The alarm information is messy, making operation and maintenance automation personnel Failure to keep abreast of the most important warning information

Although the use of alarm classification can solve this problem to a certain extent, the display of alarms still lacks a graphical and intuitive display method
