A Study of Various Traction Transformers & Active Power Compensator in Co-Phase Traction Systems

In this paper different type of traction transformer from the transformer family is considered in the traction system. Mainly in traction power supply systems of electric railway have many issues like voltage unbalance, high active and reactive power, harmonics, etc. This problem can be solved by implementing a co phase system with a suitable traction transformer. The traction transformers that are discussed are YNvd transformer, Impedance matching transformer and Leblanc transformer. So different traction transformers are modelled and analysed using MATLAB. In this paper Active power compensator is also modelled and discussed. The simulation results of co phase traction system using different type of traction transformer are compared for better performance. Modelling and simulation is done using MATLAB R20010a software.
