Abstract

본 발명은 전력수송용 송전선의 고장발생시 그 고장을 검출하기 위하여 적용되는 보호계전 방식에서 송전단 및 수전단에서의 상태정보를 상대단에 전송하는 것에 고장구간을 명확히 구별하여 신속히 차단하도록 하는 파이롯 계전용 통신장치에 관한 것이다.The present invention is a pilot to clearly cut off the fault section in the transmission of the status information at the transmission and reception terminals to the other end in the protection relay method applied to detect the failure when the power transmission line failure occurs It relates to a communication device for relay.

본 발명의 통신장치는 송전선에 가설된 광케이블(또는 기타의 통신용 광케이블)을 이용하여 계전기 동작정보를 디지탈신호를 변환하여 송수신하는 방식으로서, 외부잡음의 영향이 없고 평소에도 신호가 송수신되어 통신 시스템자체의 이상유무를 자동감시할 수 있으며, 부호화된 신호를 사용하므로써 전송신회도가 높아 오동작율이 낮다.The communication apparatus of the present invention is a method of converting and transmitting a relay operation information by using a optical cable (or other communication optical cable) installed on a transmission line by converting a digital signal, without the influence of external noise, and the signal is transmitted and received normally, the communication system itself It is possible to automatically monitor the abnormality of, and the use of the coded signal enables high transmission reliability and low malfunction rate.
