Power grid facility anti-seismic safety risk assessment method and device

Abstract

The invention relates to the technical field of earthquake risk assessment, particularly provides a power grid facility anti-seismic safety risk assessment method and device, and aims to solve the technical problem of how to integrally and comprehensively know the specific influence range and intensity distribution of a certain earthquake event and the relevant information of an earthquake source position. The method comprising the steps of analyzing seismic intensity of a position where a power grid facility is located during an earthquake; calculating safety coefficients of all the power grid facilities within an earthquake influence range based on the seismic intensity of the positions of the power grid facilities; and carrying out risk assessment on all the power grid facilities in the earthquake influence range based on the safety coefficients of all the power grid facilities in the earthquake influence range. According to the technical scheme provided by the invention, the overall influence range and intensity distribution of the earthquake can be displayed through a map, the complete information of the earthquake can be displayed, further, the earthquake influence degree of the electric power facility can be matched through a map matching mode, and the facility does not need to have monitoring point monitoring data.

Description

technical field [0001] The invention relates to the technical field of earthquake risk assessment, in particular to a method and device for assessing earthquake resistance safety risks of power grid facilities. Background technique [0002] The seismic safety assessment system for power grid facilities is currently mainly based on the monitoring equipment installed in substations, towers and other locations to collect seismic data at monitoring locations. Risk assessment is then carried out by relevant assessment methods. Since the relevant assessment is based on the actual location monitoring equipment, if some power grid facilities are not installed with monitoring equipment, the accurate seismic intensity of the location cannot be obtained. [0003] At the same time, due to such a mainstream assessment method, it is impossible to fully understand the specific impact range and intensity distribution of a certain earthquake event, as well as information related to the loca...
