Title:
MOTOR TRAIN UNIT TRACTION SYSTEM AND ENERGY CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2017/076161
Kind Code:
A1
Abstract:
A motor train unit traction system and an energy control method. The traction system comprises: a high-speed circuit breaker (1Q02), connected to a power supply grid; a main/auxiliary inverter, connected to the high-speed circuit breaker (1Q02) via an intermediate DC loop, and used for inverting a DC provided by the power supply grid into an AC and then outputting the AC; a high-voltage detection box, connected to the power supply grid, and used for detecting the voltage of the power supply grid; and a drive control unit (DCU), judging, on the basis of a detection result of the high-voltage detection box, whether the voltage of the power supply grid is normal, and disconnecting the high-speed circuit breaker (1Q02) when the voltage of the power supply grid is over-high, so as to perform over-voltage protection on the main/auxiliary inverter.
