ABSTRACT

The existing North-South and East-West (NSEW) Line has been in operational for more than 20 years. As the power supply equipment in NSEW line ages and coupled with increasing energy cost, engineers are faced with the challenge to enhance the existing traction system to make it more energy efficient without compromising the operational performance and with existing site constraints.

This paper presents the experience on the use of inverters and the use of double converters to enhance energy recovery in the existing NSEW Line. The paper also outline the consideration needed to maximize the energy recovery in the traction network as well as meeting the physical constraint in the existing stations.

Keywords: Double converter, Inverter.
