The use of variable frequency induction motor for electric lifting actuator of dragline

The aim of the research is enhancement of efficiency of dragline drives in mines, cost saving in excavation and re-excavation of rocks and reduction of energy consumption. As a way of enhancing efficiency, it is proposed to replace DC drives by variable frequency induction motors with direct control of moment. The main tool of the research is the developed mathematical model of a variable frequency induction motor, which allows investigating transient processes in the motors and lifting actuators of draglines, as well as changes in rotation speed of the motors within a work cycle, in the torque of the motor and in the forces in the lift cables. The article offers a detailed description of the development of the model, using Matlab/Simulink and SimPowerSystem libraries. The research used the modern theory of electric motor drives, control science and mathematical modeling. The authors suggest to use the method of the direct moment and frequency control and recommend its implementation—algorithmic and technical. The use of the variable frequency induction motors leads to better functioning of the technology cycle, substantial saving of cost of rock excavation and haulage in open pit mines, reduction of energy consumption and wear of major assemblies. The working knowledge of the research includes the developed mathematical model of the variable frequency induction motor for lifting actuators of draglines and the approved algorithm of the technology work cycle. The authors make some proposals on selection of home equipment for variable frequency motors.
