Urban transit system must secure fast, safe and reliable transportation capacity as a metropolitan mass transit. For this purpose, it is important to make all the sub-systems (which consist of EMU, power feeding, signalling & telecommunication, railway, platform facility, and control system and so on) work well. To operate all the systems effectively and reliably, a maintenance measure optimal to each system's characteristics is need to be established and executed. So highly reliable maintenance is need to be performed. But, EMU maintenance methods suitable to its own model and EMU's line are not introduced yet. This study examined a few example mainly to secure reliability on a maintenance quality in operating method and feature of train maintenance system based on travel distance.

This paper describes the method of how to improve the probability of the tracing stopping ratio which is the most important factor in Automatic Train Operation (ATO). Aspects of improving the performance of automatic driving, the followings are investigated and studied : the interface between the signal system and the vehicle, the need to improve braking system, test method of blending brakes, how to minimize the delay of commands for real-time control. In this study, we applied this method to prove the effectiveness in DAEJEON LINE1.
에너지저장시스템의 충, 방전 Auto Level-Tuning 알고리즘에 관한 연구

This paper is about control algorithms that bi-direction DC-DC Converter using Super Capacitor and regenerative power from DC feeding system in train. In order to take advantage of regenerative energy efficient, charge and discharge level value of energy storage system serve as an important factor. Respect to output fluctuations of the substation and catenary voltage changing, we offers Charge-Discharge Auto Level Tuning Algorithms to improve system following of Energy Storage System.
