Abstract: PURPOSE: An electric braking system is provided to improve performance of a motor car by stably stopping the motor car without using air braking. CONSTITUTION: An inverter(120) controls a traction motor(110) according to a setting braking torque. A load torque estimator(130) estimates the load torque of the traction motor according to a rail grade. A braking mode switch unit(140) converts a first braking mode into a second braking mode. The setting braking torque has a fixed value in the first braking mode. The setting braking torque is gradually decreased in the second braking mode. A pause control unit(150) reduces the setting braking torque based on the rotation speed and the estimated load torque of the traction motor.

Abstract: 본 발명은 전기철도시스템에 관한 것으로, 특히 전기철도시스템의 토공구간 전차선로 설계에 관한 것이다.
종래에는 전기철도시스템의 토공구간 전차선로 설계에 있어서, 전차 선로 구간의 예상부하를 선정하고 부하전류를 계산하고, 이를 전선 규격별 허용전류와 비교하여 대략 수십 %의 여유가 있는 전선을 선택하여 전차선로를 설계하였다. 그러나 전기차 운행 스케쥴 변화에 따라 부하 투입량은 달라지게 되는 바, 이때 이러한 부하 투입 변화에 따른 급전 시뮬레이션이 이루어져야 하는데, 종래에서와 같이, 간략 계산법에 의해 부하전류를 계산하게 되므로써, 이에 해당하는 최적의 토공구간 전차선로 설계가 불가능하다.
본 발명은 전기철도시스템의 토공구간 전차선로 설계시, 해당 구간에 필요한 도체에 관련된 정보를 데이터 베이스로부터 읽어 각 도체에 대한 임피던스를 연산하고, 작업자가 입력한 임피던스를 비교하여 소정의 정해진 허용범위내의 도체를 선정하여 최적의 토공구간 전차선로 시스템 설비를 설계하고자 하는 데 그 목적한 바가 있다.
