Static Frequency Converter (SFC): A Solution to Power Quality and Neutral Section Issues in Single Phase, 25 kV, 50 Hz Traction System

摘要

In the paper presented here the authors have tried to illustrate the power quality issues faced by DMRC with the conventional single phase, 25kV, 50Hz traction system with transformers viz. unbalanced loading, injection of harmonics & injection of leading reactive power in public grid, poor power factor and problems associated with phase brake/neutral section. The focus of the paper is to mitigate all the above mentioned 25kV, 50Hz traction issues by adopting Static Frequency Converter technology.
