Comprehensive defense method for wide-area meteorological disasters of power grid

Abstract

The invention provides a comprehensive defense method for wide-area meteorological disasters of a power grid. The comprehensive defense method comprises three main parts of a pre-disaster prediction and disaster risk comprehensive assessment method, disaster real-time monitoring and comprehensive disaster prevention measures and post-disaster recovery. Satellite accurate forecasting is conducted on weather along the power transmission line corridor through pre-disaster forecasting, disaster risk assessment is conducted on the power transmission lines of all the sections according to the actualstate and topographic and geomorphological information of all the positions of the line corridor, and disaster prevention equipment is deployed in advance according to the risk assessment result. When meteorological disasters occur, real-time information of tension, wind speed, temperature and the like of a line is detected in real time through a sensor of a corridor along the power transmissionline, the disaster degree is judged according to the information, and corresponding disaster prevention measures are carried out according to the disaster degree. After meteorological disasters occur,post-disaster reconstruction and recovery work is actively carried out.

Description

technical field [0001] The patent of the invention belongs to the technical field of disaster prevention and mitigation, and specifically relates to a comprehensive defense method for wide-area meteorological disasters in a power grid. Background technique [0002] In recent years, with changes in global climate conditions, the incidence of meteorological disasters has risen sharply. my country's vast territory and diverse topography make it one of the countries most affected by meteorological conditions in the world. In recent years, as many as 400 million people have been affected by disasters such as typhoons, heavy rains, hail, cold waves, strong winds, and blizzards in my country every year. According to statistics, my country's meteorological disasters have many types, wide range of influence, high frequency of occurrence and long duration. Statistics show that more than 70% of natural disasters in my country are related to meteorology, and meteorological disasters b...
