METHOD FOR PREDICTING METEOROLOGICAL RISKS ON AN OVERHEAD ELECTRICAL NETWORK INFRASTRUCTURE

摘要

A method for determining the interruption risk of power grid infrastructure in a region. The power grid infrastructure in the region includes a certain number of NDEP high-voltage overhead starting, which is called class D high-voltage overhead starting, including:-For each HT takeoff in the territory, calculate PD (100) at least once, and shear the takeoff with the environmental covariate Xi according to the equation in the Cox model. The covariate Xi contains the data predicting the storm according to the territory grid, as well as the data of these HT routes and HT takeoff positions;-At least one step of calculating the number of cuts on the territory or part of the territory;-At least one display and / or backup (120) interrupt count data based on the startup that may be affected and the interrupt probability of each startup.
