Abstract
The application of multilevel converters for traction drive systems is being investigated. The main
advantage of this kind of topology is that it can generate almost perfect current or voltage waveforms,
because it is modulated by amplitude instead of pulse-width. That means that the pulsating torque
generated by harmonics can be eliminated, and power losses into the machine due to harmonic
currents can also be eliminated. Another advantage of this kind of drive is that the switching frequency
and power rating of the semi ....etc

In this seminar a method for wideband harmonic compensation is presented. The main circuit configuration of the system is shown in Fig. 2. The system compensates the low order harmonics using a simple computational control delay compensation method, while the high order harmonics are filtered with a small passive high pass filter. In the system the whole filtering band of the APF is utilized and the filtering performance is recovered with an HPF when the ability of the APF to filter harmonics effectively is impaired. This way the size of the pa ....etc

Electric Traction Supply System on Indian Railways


abstract
Introduction
Indian Railways is the largest government institutional costumer and purchaser from various Electricity boards and other Electric Supply Authorities. Out of total RKM 19000 RKM is electrified which carries 60% of total freight as well as passenger traffic across India.
Annually, approximately 30 billion units of electricity is consumed by Railways, out of which 10.4 billion units are used for electric traction purpose. Railway is paying approximate Rs. 5 ....etc

hello sir,
i am a electrical engineer student and studied electrical traction and drives in my semester paper.i would definitely like to know about the electric traction system in indian railways.
hence i will be feel very obliged if you send me dis paper as soon as possible.so that i would gain some knowledge and able to put dis in front of other.
thank you

ABSTRACT

This paper focuses on a shunt active filter based on the detection of harmonic voltages at the point of installation. The objective of the active filter is to attenuate harmonic propagation resulting from series/parallel resonance between capacitors for power factor correction and line inductors in a power distribution line. The active filter acts as a low resistor to the external circuit for harmonic frequencies, and it is installed on the end bus of the power distribution line, just like a 50 O terminator installed on the end ter ....etc
