DC 급전시뮬레이션을 통한 도시철도 회생에너지 활용 분석

초록

This paper deals with regenerative energy in railway system which one of the largest customer in terms ofload capability. Unlike the other loads of power system, loads of railway systems change in time and space. It has acharacteristic amount of generating regenerative energy by frequent starting and braking in railway system. Therefore, itis expected higher utilization in railway system than the other systems. The purpose of DC power supply simulation isanalyzing backed energy, regenerative energy by each railway vehicle and substation. In this paper, regenerative energyutilization are analyzed using DC power supply simulation and it is performed changing major influence on the designsuch as the number of installing absorber, internal resistance value, no-load voltage value at substation or operatingparameters at regenerative energy utilization. After simulating, results are compared and analyzed.
