Effect of traction substation for high speed railway in Indonesia

Abstract

This paper discuss about effect of traction substation for high speed railway in Indonesia. The purpose of this paper is to obtain magnitude of voltage and current unbalance due to traction substation that perceived by system and generator adjacent to traction substation. Analysis is performed by doing simulation of 5 scenarios in simple system model that created in power system simulation program. These 5 scenarios are being performed to represent the actual condition of Indonesia power system. Based on the analysis of simulation result, it can be stated that the magnitude of voltage and current unbalance on system and generator are influenced by magnitude of system short circuit level (SCL), position of supply substation to traction location, amount number of power plant near to traction location, percentage impedance of generator transformer, and the magnitude of generator load.
