Method for measuring influence of regional environment erosion on service life of power transmission and distribution facility of power grid

The invention belongs to the technical field of power grid systems, and particularly relates to a method for determining the influence of regional environment erosion on the service life of a power grid power transmission and distribution facility, and the method comprises the following steps: S1, carrying out the comprehensive corrosion environment analysis considering the superposition of an acid rain high-humidity atmospheric environment and an ocean climate environment; according to the invention, the service life of the power transmission and distribution fixed assets is scientifically measured, calculated and analyzed on the basis of multi-dimensional data analysis such as disclosed literature data, field experimental data, asset history, scrap vouchers, target region geography and natural environment data statistics; a power grid equipment technical life actual level measurement analysis conclusion is taken as a basic reference, and economic life calculation and actual scrapping age limit distribution
