High-Voltage Converter Technology Applied in Coal Mining Ventilator

Abstract:

High-voltage converter technology applied in coal mining ventilator could gain a great deal of operating effectiveness and economic benefits. This paper illustrates the reformation of main ventilation system in some coal mine of Shanxi province. The defective operation conditions of previous mining ventilator and the advantage of converter control system applied in the mining ventilator are also proposed by this paper. The mathematical model of direct torque control (DTC) method used in the system is analyzed by giving dynamic model of stator flux oriented. The transformed design of converter control system with the benefits of highly enhanced energy-saving and environmental protections is involved as well as its operating statistics on energy-saving effect.
