A detailed positive sequence admittance matrix representation of a single phase traction feeder system has been developed and results presented to assess the performance of harmonic filters. Similarly an iterative algorithm to solve for the operation of the locomotive's single phase convertors and their associated a.c. and d.c. systems has been discussed and applied to various a.c. and d.c. systems with both fully and half controlled operation. The main result of this study is that classical methods of fixed current injects based on a flat d.c. current waveform are inadequate. This is especially true of the half-controlled case. The choice of d.c. motor representation is not so important, and in the absence of accurate information the R/L series model is adequate.
