The paper reports a methodology to analyze the voltage unbalance induced by a railway line electrified at 2×25 kV 50 Hz on the main high voltage network.Starting from the knowledge of maximum power consumption by trains, carrying out a train performance, a Simulink model of a real railway line electrified at 2×25 k-50 Hz has been carried out in order to calculate the voltage unbalance.Taken into account CEI EN 50160 and IEEE Std. 1159-1995, some technical solution have been proposed in order to mitigate the voltage unbalance under threshold limit imposed by standard.

Abstract
The paper reports a methodology to analyze the voltage unbalance induced by a railway line electrified at 2×25 kV 50 Hz on the main high voltage network.Starting from the knowledge of maximum power consumption by trains, carrying out a train performance, a Simulink model of a real railway line electrified at 2×25 k-50 Hz has been carried out in order to calculate the voltage unbalance.Taken into account CEI EN 50160 and IEEE Std. 1159-1995, some technical solution have been proposed in order to mitigate the voltage unbalance under threshold limit imposed by standard.| File | Dimensione | Formato | |
