SVC Refurbishment Experience for Critical Coal Train Haulage Network
OBJECTIVES• Refurbishment of 10 SVCs for
voltage support in a traction supply network
• Apply latest available well-proven technology
Session 3 – Paper 0611
AuthorsTuan VU Principal Consultant Powerlink Queensland, Australia,Anthony JOHNSON Marketing Manager Siemens Ltd., Australia
APPROACHInstallation and operation of a mobile SVC system during refurbishment works
48hr cut-in period and 48hr cut-out period for the mobile SVC providing minimum down-time for each substation
RESULTS• Security of the transportation system• Minimization of SVC outage times
during the transition phase• Very fast re-energization of the
existing SVC components• Maximal reliability with minimal
maintenance • Improvement in network security

After 48 hrs – Step 1 finished and all SVC Functions available
Work is done –and the SVC operates properly
Step 2:
4 Weeks for full Refurbishment of Valves, Controls & Protection in the SVC Building
Step 3:
48 hrs for Disconnection of SVC Container and Energization of the fully refurbished QR SVC
