electric traction in railways paper in ieee format

This paper summarizes recent trends of electric traction technologies based on power electronics. Continuous electric power collection played a substantial role in rapid growth of commercial service of electric railways in the early 20th century. AC traction as an achievement of power electronics after 1980's contributes to the present efficient high-speed mass transportation service. Regenerative brakes and consequent power management using power converters and electric energy storages enhance ecological advantages of rail-guided transportation.Electric Traction is the most common public transport used for the long distance travel by common people in India. This paper investigate the harmonics of Electric Traction system in Indian railways by taking measurements at 110/25kV traction substations. This also calculates the total harmonic distortion of current and voltage harmonics in the feeder of the traction substation. This gives an idea about the issues due to the presence of harmonics in Traction systems to the public utility systems. A single tuned LC filter, tuned to filter out 3rd harmonic is proposed at the end.The objective of this paper is initially to present a basic modeling of the railway traction system. This model includes the basic technologies used today. The voltage dependencies of the maximal possible power consumption as well as the maximal velocity of the common Rc-locomotives are included. The latter is very crucial for the studies of time table sensitivity, which is of our immediate interest. Moreover, a method is presented, that estimates the expected train delay time for a given feeding technology. The reference timetable assumes the same train and surrounding conditions, but no voltage drops. In the numerical example where the developed model is applied to a realistic test system, a set of possible amounts of railway traffic are treated as uncertainties.
