Sustainable Mining and Metallurgy

This paper discussed the application of intelligent power supply and distribution system in coal preparation plant, introduce the technology of automatic inspection tracking system, remote control system of equipment, online approval system of power outage and transmission, and introduced the composition, function and working principle of each system in detail. The system significantly improves the energy utilization efficiency and intelligent management level of the coal preparation plant, reduces the time waste and operation complexity under the traditional power supply and distribution mode, strengthens the safety and reliability of the power supply and distribution operation, helps to reduce energy consumption and production emissions, and promotes the transformation of the coal preparation plant to the direction of energy saving, environmental protection and green development. The reliability of the power supply and distribution system is realized through the threelayer locking protection mechanism, and the paperless and online mobile operation is realized in the whole business process, which greatly improves the work efficiency and production safety.
