Trevallyn Power Station - Replacement Program - Machine #2 Refurbishment

Trevallyn Power Station - Replacement Program - Machine #2 Refurbishment

Event Overview

Tasmania has an international reputation as a leader in providing sustainable electricity solutions for our communities, including our extensive hydro power system of dams and power stations.
The engineering team plays a critical role in maintaining these valuable assets and achieving service lives of 100+ years.

 

This site tour will explore how a multi discipline team is refurbishing Hydro Tasmania's 63 year old ‘Machine No 2’ at the Trevallyn Power Station (TR2) to achieve a further 30+ years of reliable operation.

 

Connect with other local engineers and learn about the team’s experiences in:

  • solving complex, practical and challenging problems with aged assets, 
  • project management, 
  • contracts and finance, 
  • site management, 
  • creating local solutions to needs for manufacturing and machining, 
  • project management, and 
  • general lessons in asset refurbishment and management.

 

Hydro Tasmania will also speak of their evolving role in engineering vocational education, commencing with students’ decisions to embrace STEM subjects during their secondary education.

Background on the refurbishment project:

Trevallyn is a run-of-the-river hydroelectric power station, located adjacent to the Tamar River north of Launceston, making use of daily flows down the South Esk River.

The power station was commissioned in 1955 by the Hydro Electric Commission, replacing the iconic Duck Reach Power Station (the first publicly owned hydro-electric plant in the Southern Hemisphere).

After ~60 years of service, Hydro Tasmania’s Machine No 2 Trevallyn (TR2) is to be refurbished. The overall objective is to return the machine to a condition that will enable a further 30+ years of reliable operation.

The site-based component of the refurbishment work involves the:

  • complete disassembly of the turbine, 
  • removal of the exciter and rotor, 
  • recoating of the spiral casing, 
  • site machining of the key spiral casing interface points, 
  • refurbishment of the rotor and stator, 
  • refurbishment of the governor oil and alternator oil systems,
  • reassembly of the turbine, alternator and exciter and
  • installation of new machine governing, 
  • installation of new electrical and control system.
