Title:
HYBRID SHUNTING LOCOMOTIVE TRACTION CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2023/015813
Kind Code:
A1
Abstract:
A hybrid shunting locomotive traction control method. When a locomotive enters a traction working condition, a vehicle control unit calculates a target traction force according to a driver controller handle level, a power battery state, a generator set state, and a locomotive speed which are collected; the vehicle control unit sends the target traction force to a traction inverter control unit by means of a network, and a traction inverter of the traction inverter control unit generates a variable-frequency variable-voltage three-phase alternating current according to the target traction force to drive a traction motor, so as to realize output of the traction force of the locomotive.
