Title:
DEBUGGING SYSTEM FOR TRACTION CONVERTER OF INTERNAL COMBUSTION LOCOMOTIVE
Document Type and Number:
WIPO Patent Application WO/2018/045631
Kind Code:
A1
Abstract:
A debugging system for a traction converter of an internal combustion locomotive, comprising: a debugging device subsystem that comprises a first variable-frequency drive, a main dynamo, a traction converter, a second slave motor, and at least one load. The traction converter comprises: a rectifying and inverse unit, a traction control unit, and an auxiliary control unit; the first variable-frequency drive is used for performing frequency conversion on a three-phase alternating current of a power grid, and then sending the frequency-converted three-phase alternating current to the first slave motor to drive the main dynamo to rotate; the three-phase alternating current generated by the main dynamo in operation is converted by a corresponding component in the traction converter and is then used for a debugging test of the traction converter of the internal combustion locomotive. In the debugging system for the traction converter of the internal combustion locomotive, a diesel engine is replaced with the first variable-frequency drive, so that the test system is changed from an electromechanical hybrid system to an electrical system, thereby reducing the complexity of the system.
