Improvement of two-drum multimotor electric drive of belt conveyor using its traction factor

The study focuses on a traction factor of a two-drum multimotor variable-frequency electric drive of a belt conveyor. The relevance of the topic is governed by the problem connected with the nonuniform loading of variable-speed drives of conveyors in coal mines, which affects efficiency of the equipment. The research objective is improvement of the mentioned-type drive by means of introduction of an automatic control meant to reduce the load nonuniformity of each electric drive and to enhance thereby the energy and technical efficiency of a conveying unit. The subject of research into operation of multimotor systems of multi-drum drives is selected to be mine belt conveyor 2L100U-01. The main research method is computer modeling of static and dynamic operating modes of the research subject in MATLAB/Simulink. In the developed model, the author proposes an algorithmic implementation of determination of tractive forces and traction factors of all drums, as well as a structure flowchart of load balancing between all motors of a variable-frequency drive, with the direct control. The experimental results prove the ability of the developed system to ensure both stable ratio of tractive forces of driving drums and load balancing between the drives accurate within 1.8% as against the speed control only. The conclusion is drawn about the expediency of the proposed approach to the improvement of multimotor electric drives of mine conveyors.
