Most narrow-gauge vehicles driven by DC motor now, as DC drive due to power constraints and high maintenance costs, most of them will gradually be replaced by AC drives. But VVVF(Variable Voltage Variable Frequency) control method adopt in some running narrow-track traction locomotives, that can reduce over-current with load starting and should be compensated at low frequency. Based on study the Control strategies of narrow-track locomotives, comparing with the characteristics of power distribution of dual-motor drive system. The motor ought to have the same mechanical feature in dual-motor drive system, vector control strategy select in the control system. Experiments prove the system has good performance of stability, reliability, and good control performance, which can meet the narrow-track traction locomotive control requirements.
