摘要：

The article shows the peculiarity of the system of technological automation of the newest Simatic S7-1500 PLCs, for electric drives of hoisting transport machines, the analysis of control systems for electric drives of operating mine hoisting machines of mining complexes. One of the main ways to increase the energy efficiency of MLM is to replace old asynchronous electric motors with a phase rotor with squirrel cage induction motors designed for operation in a frequency-controlled electric drive. The introduction of a frequency converter and an electric drive control system, which together allow the recovery of electricity in the supply network in the mode of generator braking. Thus, the system for automated control of the mine hoisting machine based on the Simatic S7-1500 PLC, with the developed control algorithm, is an integrated energy-efficient control system, which it is advisable to use in the management of the SHM.
