CONFIGURATION OF FEEDING SYSTEM IN ELECTRIC RAILWAY

초록

Electric rolling stock is useful to save a energy in comparison with diesel. Normally Auto- Transformer (AT) feeding system is utilized because of benefits of voltage drop, telecommunication induction and son on. Feeding system adopted by CL (Conventional Line) is separating up and down lines, while HSL (High Speed Line) adopted one with parallel connection in Korea. The purpose of this paper is to assess advantage and disadvantage of each system by conducting fault and harmonics simulation. Voltage drop, fault impedance, fault current, fault location and harmonics magnification are reviewed. By doing this, the study result suggests a standard to select feeding system."
