Equipment statistical analysis method and device based on new-generation centralized control station system

The invention discloses an equipment statistical analysis method and device based on a new-generation centralized control station system, and relates to the technical field of electric power automation system application, and the method comprises the steps: reading the incidence relation of equipment, interval, voltage class, transformer substation and operation and maintenance class from a real-time database of an electric power system; constructing a multi-layer mapping table in a memory of the centralized control station based on the association relationship; the multi-layer mapping table comprises configuration data and real-time data of the power system; reading operation data of the equipment from the real-time database; and updating the multi-layer mapping table based on the operation data and a preset statistical rule. The technical problems that in the prior art, data collection, processing and analysis are delayed, and the requirement for real-time monitoring of power equipment cannot be met are sol
