Vacuum – a logical progression in on-load tap-changer technology

Presented by Anders Hakansson, Territory Sales and Business Development Manager, Insulation and Components, Transformers, ABB Australia

For over 100 years ABB has been producing On-Load Tap-changers (OLTC) and pioneered a broad spectrum of high voltage technologies in the field of transformation and transmission. This accumulated knowledge has been a prerequisite for the development of a new generation of tap-changers where absolute reliability is a fundamental requirement.

The seminar will take you through the OLTC fundamentals and voltage regulation. Traditional technology as well as the new generation tap-changers that utilize vacuum technology will be discussed.. With vacuum technology, electrical arc quenching takes place in a vacuum and not in oil. This substantially reduces contact wear, thus residues from arcing do not pollute the insulating oil and the need for maintenance will be reduced. Since the OLTC is the only moving part in the transformer, maintenance requirements will be presented and easy up-grading possibilities.

Control System technology to extend the lifecycle of installed assets.

Presented by Sebastian Herz, Tech Sales Support and Marketing Manager, ABB in SG

Aging industrial production facilities not only lack modern monitoring and control functionalities, but are also vulnerable due to missing cyber security protection measures. In addition, plants from the 80’s, 90’s and early 2000’s are often patched networks as a combination of systems from different vendors, which makes it difficult for operators to maintain. Making it possible to combine systems under one common platform and upgrade existing installations in a step-by-step approach, doesn’t only lower the initial investment costs, but also often allows online-upgrades without a single hour of plant shutdown and lost production. The efficiency inherent in ABB’s ability to perform online upgrades, even during complex batch production scenarios, means that our customers maintain profitability through continuous production.  

This presentation highlights a customer success story showing how customers can “Use what you have to get what you need” and learn how your current investment can be saved and “used, as long as it makes sense”. There are upgrade and evolution models beyond the traditional “rip & replace” strategy that will allow cost-efficient plant modernization.  

Battery/diesel grid-connected microgrids: a large-scale, industry-based case study of future microgrid capabilities.

Juergen Zimmermann, Business Development and Technology Manager - Microgrids and Distributed Generation, ABB in Australia (Auckland event) and Perry Field, General Manager,Power Conditioning Products, ABB in New Zealand (Chch event)

As large scale battery technology and economies of scale improve, many industrial utilities are investigating the use of battery technology as the basis for Grid Energy Storage Systems (GESS). 

In this case study, we examine the issues faced by a Melbourne based utility, AusNet Services.  AusNet Services is trialing a non-network option to manage peak demand and defer network augmentation.  The trial will investigate the capabilities of grid-connected microgrids to provide peak demand support.  By embedding a generation source close to the load, AusNet Services is studying the effects this has on postponing traditional network investment.

We also discuss the solution, a 1MWh 1C lithium battery system which interfaces to the microgrid through a 1MVA (an inverter-coupled energy storage system), a 1MVA diesel generator, a 3 MVA three-winding transformer and a SF6 gas-circuit breaker-based ring main unit with associated power protection systems.
