This paper details methods used to verify the adequacy of a dc traction power supply for design of a rail transit system. Examples of the approach are given for a major subway system presently under construction. The performance of trains operating at maximum system design capacity is modelled using a train simulation program. Using a dc network analyser program with the power demand results of the train simulation program, the maximum train operating timeable, and a model of the ac and dc electrical supply system, the electrical performance of the entire system can be modelled over a 24-hour period. The results of this analysis are used to determine: train voltage at a level sufficient to ensure train schedules; adequacy of traction transformers, rectifier, and switchgear ratings; sizes of the overhead contact system conductors, and ac and dc feeder cables; and power and energy demands at the utility company's supply points for initial and final time-table operations.
