Aurecon presenting on substation design trends at Cigre Colloquium

Hobson substation

2 September 2013 - Aurecon substation and asset management experts Joe Tusek, James Herbert and John Szmalko will be presenting at the Cigre Study Committee Colloquium in Brisbane on 9-10 September 2013.

Themed “managing substations in the power system of the future - trends in technology, design, materials and diagnostics”, the colloquium ties in with Cigre’s strategic focus.

Joe Tusek, Technical Director, Energy Services, Aurecon, Cigre’s colloquium organising committee, will be jointly presenting two papers.

‘Tomorrow's Substation - Realising the Substation for the Power System of the Future’ summarises recent developments and trends in substation design, materials and technology.

“The paper will outline how some asset owners and designers are changing the way they design and implement substations to help them better meet market and industry needs,” said Joe. 

“Integral to this will be new materials and technologies that will change the way we think about and manage HV plant.”

‘Basis Function Modelling of Transformer Frequency Response Analysis using PSO (Particle Swarm Optimisation)’ discusses how frequency localising basis functions can be used to represent a transfer function spanning from 20Hz to 10MHz that has over 100 resonances.

“Approaches like these are needed to change power transformer frequency response analysis (used to determine if transformer windings have become distorted which results in severely weakened insulation) from a subjective measurement to a well-defined and automatic classification scheme for transformer defects,” said Joe.

Aurecon’s James Herbert, Senior Electrical Engineer and John Szmalko, Technical Director, will be presenting a case study on Auckland’s Hobson Street Substation, a technically complex project which required significant innovations to overcome a range of project challenges including exceptionally tight spatial constraints, unstable historic retaining walls and design risks around explosion, fire and earthquakes. The project was undertaken to a very tight timeframe with a 17 stage consent process and the main structure was built in just over 21 months to enable plant installation and through-link cable connections to be made.
