Simulation Assessment of the Existing KTMB Klang Valley 25kV Traction Power System Adequacy to Support the New 6-Car Train with Shorter Headway Commuter Service Operation

Abstract:

In 2012, KTMB launched a new fleet of China-made 6-car electric multiple units (EMUs) to augment their existing 3-car EMUs, the objective being to expand the capacity of its Klang Valley train commuter service from 33,000 to 95,000 passengers during the morning and afternoon peak hours. Due to significant expansion in train traffic density, it was essential to investigate whether the existing 25kV overhead centenary system (OCS) electrical network infrastructure could support the ensuing electrical power demands/loads due to the additional tractive effort of the 6-car trains and increased train traffic density. Traction power simulation study using MM-TRAIN software was conducted for this purpose. This paper illustrates the indispensable tool of traction power simulation software to access the performance of moving rail traction loads under normal (no outage) and under first emergency feeding conditions (n-1 outage contingency)
