Embodiment Construction

[0027] Such as Figure 1 to Figure 3 As shown, a method for establishing a GIS database for emergency repair of electric power under natural disasters adopts an object-oriented design method to classify electronic maps within the distribution range of power facilities and identify elements step by step. Modeling technology, creating a high-precision three-dimensional component GIS model, storing each component model according to the distribution relationship of power emergency supplies, and finally forming a GIS database for natural disaster power emergency repairs.

[0028]The GIS database is based on the actual situation to establish a power emergency repair dispatching command center database. By standardizing the resource storage points in various places, the location of line towers, and traffic routes, etc., the effective integration of emergency repair materials such as emergency repair towers and other resources is realized. In the specific implementation, the main syst...

Abstract

The invention provides a method for building a GIS database for power repair under natural disasters. The method comprises the steps: employing an object-oriented design method to carry out stepped classification and element marking of an electronic map in the distribution range of the power facilities; using the three-dimensional modeling technology to create a high-precision three-dimensional component GIS model based on the classification and marking result; enabling all component models to be stored according to the power rescue material distribution relation; and finally forming a GIS database for power repair under natural disasters. This database can store the resource storage point of repair towers at each place, pole positions and traffic routes, can improve the power supply recovery efficiency after power grid failure or disaster and saves the cost. The management staff can keep abreast of the situation of repair supplies, accident area pole situation and road conditions through the database, can carry out the real-time inquiry of on-site information conveniently, formulates the best repair program, and timely arrange the scheduling and repair through system analysis.

Description

technical field [0001] The invention relates to the technical field of power system disaster response measures, in particular to a method for establishing a GIS database for power emergency repair under natural disasters. Background technique [0002] In recent years, the natural environment has changed badly, and natural disasters have occurred frequently. The large-scale continuous low-temperature rain, snow and freezing disasters in the south, the Ya'an earthquake in Sichuan, and the floods in the Heilongjiang River Basin have caused great harm to the safety of the power grid. Large-scale, long-term, and high-intensity natural disasters will lead to power grid transmission line collapse, disconnection and wire flashover accidents, which will cause great harm to the safe operation of the power grid. Since the power system is the stable foundation of social economic development, order and public welfare, it is usually required to restore the power supply in the shortest tim...
