SLIP CONTROL METHOD FOR PROPULSION CONTROL APPARATUS FOR HIGH-SPEED TRAIN

摘要

The present invention relates to a slip control method for a propulsion control apparatus for a high-speed train, which comprises as follows: a step of sensing the racing of an axle of a high-speed train when a slip of the axle of the high-speed train occurs; a step of reducing the traction power of the high-speed train to a preset reduction when the racing is sensed and maintaining the traction power for a preset maintenance time; a step of gradually recovering the traction power maintained for the maintenance time over a preset recovery time; and a step of adjusting the increase of the recovery pattern of the traction power by stages depending on the number of racing of the axle of the high-speed train. Therefore, the slip control method for a propulsion control apparatus for a high-speed train can realize re-adhesive control by reducing the incidence rate of recurrent racing through the adjustment of the traction power pattern, can prevent emergency brake coupling due to reduced air pressure in a vehicle, and can prevent damage to a tripod by adjusting the sand spraying timing.;COPYRIGHT KIPO 2014;[Reference numerals] (110) Main transformer; (120) Propulsion control apparatus; (121) Converter; (122) Inverter; (130) Controller; (140) Memory unit; (150) Speed measuring sensor; (160) Motor
