Voltage unbalance problems and solutions for electrified railway systems
Shahnia, F. and Esmaeilzadeh, R. (2005) Voltage unbalance problems and solutions for electrified railway systems. In: 7th International Conference Modern Electric Traction in Integrated XXI Century Europe (MET) 2005, Sept/Oct 2005, Warsaw, Poland
Voltage and current unbalance problems of power networks due to AC electrified railway systems are studied and their influences such as the voltage unbalance factor and the current negative sequence contribution factor injected to the network are calculated. Several methods can be used for reducing the power quality unbalance problems which have been proposed and the best of them is chosen by comparing the results of their unbalance and current negative sequence contribution factors.
