Electric power transmission line and disaster geographic information system

Abstract

The invention discloses an electric power transmission line and disaster geographic information system. The electric power transmission line and disaster geographic information system comprises an electronic map part which is used for generating a basic geographic information layer and comprises a satellite imagery layer, a disastrous meteorological environment map information part comprising lightning, pollution area, wind area, ice area, bird trouble geographic information layers, a data base part for building and maintaining electric power transmission line information, electric power transmission line tower information, management unit information and tower dynamic operation information and a line corridor information part. For different line management line corridor information, different power transmission corridor parameters are set dynamically according to terrain environment of lines, and therefore evaluation of influence of various disastrous meteorological environment parameters on a power grid is refined. The electric power transmission line and disaster geographic information system can effectively support planning, design and stable and deep construction work development of a smart power grid and improve comprehensive monitoring and management efficiency of operating conditions of power transmission and transformation equipment.

Description

technical field [0001] The invention belongs to the field of geographic information systems, in particular to a geographic information system for power transmission lines and a geographic information system for disasters. Background technique [0002] The construction of the transmission grid has entered a new stage of strong and smart grid construction, and more attention has been paid to the quality control of the whole process from planning to preliminary design, construction, equipment, and operation. In particular, disastrous weather information and polluted area information have a huge impact on the design and operation of power transmission lines. [0003] However, the existing catastrophic meteorological parameters of the power grid, such as minefield map system, paper polluted area map, wind area monitoring data, icing observation images, wire dancing records, line bird damage data, etc., have scattered information, chaotic data, and different display methods. Unif...

Problems solved by technology

[0003] However, the existing catastrophic meteorological parameters of the power grid, such as minefield map system, paper polluted area map, wind area monitoring data, icing observation images, wire dancing records, line bird damage data, etc., have scattered information, chaotic data, and different display methods. Unified and incomplete, it is difficult to strongly support the planning and design of the power grid, and it also brings inconvenience to the comprehensive monitoring and management of the operation status of power transmission and transformation equipment, which seriously restricts the in-depth advancement of smart grid construction.

[0004] In addition, the existing analysis of disastrous meteorological parameters only considers the problem from the perspective of the transmission line itself, and we propose to evaluate the possible impact of natural disasters on the line through the dynamic line corridor
