Method for identifying key technical factors of power grid engineering construction

The invention discloses a method for identifying key technical factors of power grid engineering construction, and belongs to the technical field of power systems. Comprising the steps of 1, collecting power grid main network engineering data over the years and constructing a sample set; step 2, constructing a power grid line construction project key technology identification model based on big data, inputting sample set data, and obtaining a contribution rate corresponding to a new index; and 3, calculating the influence degree of each index on the power grid line construction project, and selecting a plurality of indexes with higher influence degrees as key technologies. According to the method, standardization and effectiveness of main key technology identification in the power grid line construction process can be further improved, key technical factors which have important influences on specific power grid line engineering are reflected more comprehensively and systematically, and future operation decisi
