- W2003760044 abstract "전기철도는 전차선을 통해 차량을 구동할 수 있는 전력을 공급하며, 공급된 전류는 선로 및 접지망을 통해 변전소로 귀환한다. 국내의 경우, 이러한 귀선전류에 영향을 주는 접지망 구성은 대부분 단독 접지방식을 사용하였으나, 경부고속선의 도입과 함께 공동 접지방식의 개념이 전기철도에 적용되었다. 본 논문에서는 고속철도의 기존선 운행을 위한 전철화 구간에서 측정, 분석한 귀선전류를 기반으로 전철화 구간에 있어서의 접지방식과 귀선전류의 관계를 분석하였다. 이러한 분석은 경부고속선 궤도회로에서 측정된 귀선전류 분석값과 경부고속선과 기존선 전철화 구간의 접지방식 비교에 따른 귀선전류의 예측값을 활용하였다. Electrical Railroads provide electric power, which can operate vehicles, via feeder wires. And the supplied current returns to the transformer substation through lines and ground net. In domestic cases, the configuration of ground net affecting such a return current mostly uses an exclusive earth method. However, along with the introduction to Gyeongbu HSL(High Speed Line), the concept of Common Earth was applied to Electrical Railroads. In this paper, based on the return currents analyzed to be measured in the electrified sections for the operation of High Speed Rails in existing lines, we analyze the relations between earth methods and return currents in electrified sections. For analysis, we utilize the measured values of return currents measured in track circuits in Gyeongbu HSL, and predictive values of those compared to the earth methods between Gyeongbu HSL and the existing electrified sections." @default.
