초록

Each feeding power is transformed 3 phases of KEPCO through SCOTT transformer and operate a electric train in AC Feeding system of electric railway. Nowaday a power conversion system, installed inside the train, generate a harmonics and has a effect on a power quality and it is necessary to install a countermeasures. This report is proposed a new technique to simulate a power system based on frequency model. The result is resonable relatively with a experimental one.
