Power quality disturbances of electrified railway

Abstract

Transportation is one of the biggest energy consumers, especially automobiles. In a world where energy conservation and environmental issues are growing concerns, the development of electric vehicle technology has taken on an accelerated pace. Electrified railway system has big advantages to save energy, environmental factor and mass capacity compare with their rivals for example automobiles and aircrafts. Therefore, the electrified railway has increased its share and importance on transportation system during the last twenty years. However, railway systems have many power quality problems. The aim of this paper is to study the effects of electrified railway systems on power system quality. Moreover, solutions to mitigate these problems will also be discussed and assessed.
