Mine electrical locomotive speed controlling modified from traditional changing DC resistance and DC chopper to VVVF,realizing mine electric locomotive to have high-performance control,saving energy and improving the reliability of operation of motor vehicles.The mine locomotive traction power control system was designed based on the microchip 16-bit single-chip microcomputer DSPIC30F6010A,realizing speed and current PI regulator of the two-loop control in mining electric locomotive to adoption of improved slip frequency control strategy and the SVPWM method. Experimental result shows the feasibility of the control strategy.
