Tribute Power Station Failure – Protection Aspects

Tribute Power Station Failure – Protection Aspects

Tribute hydroelectric power station suffered a major winding failure on 24th August 2019. This failure caused significant damage to the alternator and resulted in a forced outage of 3½ months for fault investigation and repair. The station was commissioned in 1995 and is comprised of a single underground 13.8kV, 92MVA rated generating unit.

Following on from Mr Marc Ransome’s presentation focusing on the primary system and fault investigation (https://www.eesa.org.au/member-resources/event-recordings); this presentation will provide a brief introduction to the protection scheme at Tribute and the importance of a fast acting and reliable protection scheme. It will introduce fault characteristics typical for winding failures and those pertaining to this particular failure, and detail how fault investigation contributed not only to the identification of root-cause for this failure, but plays a key role in the continuous improvement and quality assurance process for Hydro Tasmania’s protection portfolio.
