초록
This paper presents circuit model of catenery in electrified railway system. Most of (a.c.)electrified railway system adopted as AT fed power supply system. This system is fed with twice voltage. It is that AT system can be fed through longer distance. Conventional circuit model of catenary is used T equivalent circuit with lumped parameter. This model may include some problem when traction power supply system is analyzed. In addition, the model with distributed parameter is good for analysis of harmonic and EMI.
