Estimation of the Feeding Line Capacity according to Feeding Mehtod

급전방식에 따른 급전선로의 전송용량 예측

The primary objective of this paper is to examine the capacity of electrical transmission in electric railway according to the type of feeding system. Although supply capacity of railway substation are sufficient and there is no accident, due to the electrical transmission limit of feeding line the voltage breakdown may occur when large capacity of electric load at feeding line exist. So, using multi-port analysis model, we draw P-V curve due to feeding method, load, location and power factor of electric locomotive.
