Abstract :
As the primary traffic tool in coalmine, electric locomotive plays an important role to improve efficiency. On the basis of the analysis of several adjust speed control methods, direct torque control is adopted to adjust speed control of mine electric locomotive. The theoretic study has been deeply discussed on variable-frequency adjustable-speed system of asynchronous motor. Moreover, adjust speed system simulation model is established. The results of simulation show that the model has faster torque response and favorable high-speed performance. Based on the theoretic study and simulation result, an experiment system platform is implemented. The experiment testified that the system is suitable to fulfill responsibility of mine electric locomotive traction.
