The Control System Analysis of the Coal Flow on the Scrapers Conveyor in a Longwall Mining System
International Conference on Applied and Theoretical Electricity(2016)
摘要
In this article is presented and analyzed a new control system of the coal flow on the scrapers conveyor in a longwall mining system. The control of the coal flow on the scrapers conveyor, is carried out with the aid of a cascade control system. Electrical drive system of the advance and the cutting mechanism, of the longwall shearer, is done by means of induction motors. The control of speeds and electromagnetic torque of induction motors, in the advance system and cutting system from the longwall shearer, are realized using the sensorless vector control systems.
