Abstract: In view of problem of scattered and difficult management of coal mine electrical equipment, an energy management system of mine electrical equipment based on MCGS configuration software was designed. The system uses three layers structure of intelligent instruments-substation-upper computer to realize on-line monitoring of electric power data, which can store, process, count, inquire and analyze the energy consumption data of electrical equipment through the configuration software. The system can provide effective basis for improving level of energy efficiency and realization of energy saving efficiency of enterprises.
