능동형변압기가 도입된 전철급전계통의 정상상태 해석

초록

In this paper, new electric railway which has active transformer is modeled for evaluating the steady state analysis using PSCAD/EMTDC. Also, equivalent models including power supply, feeder, train and transformers are proposed for simplifying the model of the feeding system of high speed electric railway. In the case study, two systems are compared for verifying new system installed active transformer. Catenary voltage and three phase unbalance are analyzed
