Whole system simulator for AC railways

A computer-based multi-train AC simulator is developed. This general software package, written in Fortran 77, can be used for studying power consumption and train performance in single phase AC supplied railways. The simulator is constructed with full consideration of accuracy of traction equipment modelling and flexibility and efficiency of multi-train simulation. The developed simulator is used to study a proposal for a suburban railway application with a single power feeding source, applied to a 30 km section of double track. With 12 trains operating on this system, with a one second update, the simulation time for a eight minute headway operation was less than 7.5 minutes
