Static safety analysis based power grid meteorological disaster risk assessment method and device

Abstract

The invention discloses a static safety analysis based power grid meteorological disaster risk assessment method. The static safety analysis based power grid meteorological disaster risk assessment method comprises the following steps of analyzing a meteorological disaster (comprising thunder, forest fire, high wind, coating ice and the like) influence range and giving out a meteorological disaster influence device list in combination with power grid GIS (Geographic Information System) information; performing static safety analysis on devices within the meteorological disaster influence range, performing quantitative evaluation on power grid risks through a static safety analysis result and dividing five-level alarm according to risk values. Additionally, the invention also discloses a static safety analysis based power grid meteorological disaster risk assessment device. The static safety analysis based power grid meteorological disaster risk assessment method and device provide accordance for power grid meteorological disaster risk quantification and provide aid decision making for power grid comprehensive disaster prevention.

Description

technical field [0001] The invention relates to the technical field of power grid operation, in particular to a method and device for assessing the risk of meteorological disasters in a power grid based on static security analysis. Background technique [0002] Due to the diverse landform types, developed water systems, special geological structures, and frequent tectonic movements in the five southern provinces, the distribution of mountains and valleys is interspersed and the distribution of rivers is intricate. Under the influence of these factors, meteorological disasters occur frequently, especially derivative disasters such as mountain fires, lightning, rainfall, strong winds, and icing may destroy line towers, wash away and submerge substation equipment, increase the risk of power grid operation, and cause line Faults affect the reliability of power supply. [0003] In addition, power grid operators have always paid more attention to EMS-related information, and have...

Problems solved by technology

Under the influence of these factors, meteorological disasters occur frequently, especially derivative disasters such as mountain fires, lightning, rainfall, strong winds, and icing may destroy line towers, wash away and submerge substation equipment, increase the risk of power grid operation, and cause line Faults that affect power supply reliability

[0003] In addition, power grid operators have always paid more attention to EMS-related information, and have not paid enough attention to meteorological information. They cannot predict possible meteorological disasters, let alone quantify the risk of meteorological disasters, and cannot effectively carry out comprehensive disaster prevention and reduce power grid operation risks.
