A Modeling and Analysis of Electric Railway System Using Constant Power Model

정전력모델을 이용한 전기철도 시스템의 회로 모델링 및 해석기법

This paper presents a simulation method with constant power model for the train load. In power system simulation loads could be modeled as a constant power, constant current, constant Impedance or a function of voltage and frequency. At this time, however, representing a train load as the function is difficult because of the lack of data. Therefore as a first step, simulation method with a constant power model fer a train is studied, and the test result is compared with the simulation result using the constant Impedance model.
