Design of integrated management and control system for geological disasters of transmission lines based on GIS

Abstract

The geological environment of Guizhou Province is fragile, which is one of the most serious geological disaster areas in China. Frequent geological disasters have seriously affected the safe and stable operation of domestic transmission lines. At the same time, it has the system of detection, decision-making and security protection, which is still blank. Therefore, this paper uses database technology and GIS technology, first of all, clean up and integrate the data of transmission line, major geological disasters and hydrometeorology to establish a comprehensive database of transmission line geological disasters. Then, the risk assessment model of major geological disasters of transmission lines is established to extract the risk level information of major geological disasters of transmission lines and formulate differentiated operation and maintenance strategies. Finally, the integrated management and control system of transmission line geological disasters is designed to realize intelligent detection and decision-making of geological disasters, so as to prevent and reduce the losses caused by geological disasters and ensure the safe operation of power energy.
