전철전력 이상상태 실시간 감시시스템 현장설치 및 성능검증

초록

It is necessary to develop a novel technology for predicting and diagnosing abnormal conditions of the railway power system, such as voltage drop and distortion, so as to prevent a fault due to a power outage of the railway power system during railroad operation. Therefore, for intelligent management and maintenance of electric power equipment for railway system, an algorithm for an abnormal condition monitoring system based on real-time information was developed, and field installation for performance verification of the developed module was completed. In this paper, we describe the field installation process of a real-time monitoring system for abnormal conditions of the railway power system and the process of verifying the operation of the monitoring system based on data measured and recorded in real time. The monitoring system was installed on the actual test line, and the threshold value for detecting abnormal conditions was arbitrarily set for the performance verification test. As a result of the verification, it was confirmed that an appropriate alarm was generated when the abnormal condition exceeding the set threshold value occurred.
