Embodiment Construction

[0056] The rainstorm risk assessment method for power grid facilities includes the following steps in sequence:

[0057] a) Data collection: collect disaster data, rainstorm data, socio-economic data, basic geographic information data, and power grid distribution data. The disaster data is rainstorm power grid disaster data. Take the disaster data with the greatest impact and calculate the power disaster situation with the block as a unit Frequency, rainstorm data are daily precipitation statistics from meteorological stations and power meteorological monitoring stations, socioeconomic data are land area of ​​street units and power consumption in the district, basic geographic information data include water system and DEM data, power grid distribution data are substation distribution points in blocks statistics;

[0058] b) Risk assessment: According to the data collected in step a), respectively calculate the degree of disaster-causing factor by, the sensitivity of disaster-f...

Abstract

The invention relates to a power grid infrastructure rainstorm risk assessment method which sequentially comprises the steps of data collection, risk assessment, and risk rating. The method has the following advantages: power grid infrastructure rainstorm risk assessment is conducted through data collection, risk assessment and risk rating; disaster condition data, rainstorm data, social economic data, basic geographic information data and grid distribution data can be used for reference; four elements causing rainstorm and flood risk to the power grid, including the degree of disaster-inducing factors, the sensitivity of disaster-breeding environment, the vulnerability of hazard-affected body and the ability to prevent and fight against disasters, can be calculated efficiently and accurately; and the rainstorm risk can be assessed comprehensively, and the power grid rainstorm water-logging disaster risk index is divided into different grades through risk rating, which facilitates observation by operators.

Description

technical field [0001] The invention relates to a rainstorm risk assessment method for power grid facilities. Background technique [0002] One aspect of the impact of rainstorms and floods on the power grid comes from the damage caused by the wind. For example, the towers facing the seaport and the high mountain vents in the direction of typhoon landing are hit by strong typhoons exceeding the design wind speed, resulting in inverted poles and bending, causing Line tripping; the main transformer down-lead in the substation is affected by the typhoon, which causes wind deflection discharge, causing the main transformer to trip. Another aspect comes from the heavy rainfall that is often brought after the typhoon lands. The rain washes the foundation of the line tower, causing the tower to tilt or even collapse. , Floods and mudslides have a serious impact on substations, power distribution rooms, especially underground switches, causing secondary equipment such as terminal bo...
