Simulation of Three Phase AC Feeding System

Abstract

Three phase, AC feeding system for people mover system is described. The moving vehicle is assumed to be a current source of which position and current are determined by the run curve of the vehicle. Simulation of the feeding system is realized by AC electric circuit mesh method with the current source. This simulation is easily realized by the use of commercial simulator such as SPICE. With the SPICE, the dynamic operation of the thyristor converter on board can be simulated with the feeding system simultaneously. As a result, instantaneous analysis such as braking transient phenomenon or instantaneous harmonics can be simulated.
