Abstract

Electric railway lines are typically single-phase systems whose operation generates voltage unbalance in the transmission network, mainly due to trains acceleration. The design of the controller of a power electronics converter accessing energy from a flywheel to counteract such unbalance, requires accurate time-domain modelling of the railway system. In this paper, a lumped parameter equivalent circuit is proposed and solved using the root-matching method for a 2×25 kV railway system. The presented results confirm the suitability of the proposed model and pave the way for the design of a peak shaving control strategy of the traction load.
