Condition Assessment of Medium-Voltage XLPE-Insulated Cables Degraded by Water Treeing. In Australia degraded underground XLPE cables are causing disruption of electricity supplies and high community costs. There is no reliable non-invasive technique for prediction of cable condition to optimise cable replacement and refurbishment. In this project a large-scale experiment will be undertaken on 22 kV cables to ascertain the effectiveness of a new cable refurbishment technology.

In Australia degraded underground XLPE cables are causing disruption of electricity supplies and high community costs. There is no reliable non-invasive technique for prediction of cable condition to optimise cable replacement and refurbishment. In this project a large-scale experiment will be undertaken on 22 kV cables to ascertain the effectiveness of a new cable refurbishment technology. New techniques for assessment of cable condition will be developed using unique data from the ageing experiment and computer models of fundamental phenomena. Successful conclusions from this project will save the industry partner and other electricity distribution companies tens of millions of dollars.Read moreRead less
Monitoring and Maintaining the Structural Health of Bridges Using Vibration Characteristics. Bridges form an important part of our physical infrastructure system and in Queensland alone there are nearly 3000 bridges with an annual maintenance cost in excess of 20 million dollars and a replacement value in excess of 2 billion dollars. It is necessary to ensure that these bridges function safely and efficiently at all times. Bridge failure will cause disruption to normal lives and expensive repa ....Monitoring and Maintaining the Structural Health of Bridges Using Vibration Characteristics. Bridges form an important part of our physical infrastructure system and in Queensland alone there are nearly 3000 bridges with an annual maintenance cost in excess of 20 million dollars and a replacement value in excess of 2 billion dollars. It is necessary to ensure that these bridges function safely and efficiently at all times. Bridge failure will cause disruption to normal lives and expensive repairs. Towards this end, this project will develop an innovative structural health monitoring system to monitor and maintain the structural health of our bridges. The project outcomes will have immediate applications in Australia and overseas with economic and social benefits to the community.Read moreRead less

Investigation of key factors affecting the polarisation based diagnostics of power transformers. To avoid system wide power interruptions, major assets in the electricity network must be always operating satisfactorily. One of the key assets in the electricity network is the power transformer. Currently many transformers are over 50 years old and failure of a transformer may result in long interruptions in supply and the loss of millions of dollars in revenue. The ageing of transformers needs to ....Investigation of key factors affecting the polarisation based diagnostics of power transformers. To avoid system wide power interruptions, major assets in the electricity network must be always operating satisfactorily. One of the key assets in the electricity network is the power transformer. Currently many transformers are over 50 years old and failure of a transformer may result in long interruptions in supply and the loss of millions of dollars in revenue. The ageing of transformers needs to be properly monitored to avoid catastrophic failures. This project will provide an innovative solution for the better understanding of the ageing processes of transformers and help
managers make correct decisions for maintenance and replacement strategies.

better market operation and management following recent devastating blackouts in North America, UK and Italy. This project aims at investigating major mechanisms of market simulation techniques including impacts from load diversity and approaches to defining appropriate new generation entry into the market. From the outcome of this project the National Electricity Market will be able to manage the uncertainties of load diversity (one of the most common blackout causes), and efficiently minimise risk associated with decisions on new generation entry to enhance electricity supply infrastructure.

POWER DELIVERY IN A DEREGULATED ENVIRONMENT. The recent deregulation of the power industry has opened up new technical challenges that must be addressed in order to ensure fair and equitable market operation. Significant among these is the availability of alternative routes for the delivery of power, between and across different ownerships. In this scenario, a major challenge is to determine the minimum cost contractual arrangement for the delivery of required power. To achieve this, new techniq ....POWER DELIVERY IN A DEREGULATED ENVIRONMENT. The recent deregulation of the power industry has opened up new technical challenges that must be addressed in order to ensure fair and equitable market operation. Significant among these is the availability of alternative routes for the delivery of power, between and across different ownerships. In this scenario, a major challenge is to determine the minimum cost contractual arrangement for the delivery of required power. To achieve this, new techniques for the analysis of power systems are required. This proposal aims to provide solutions to these analysis problems and hence to provide software to assist with market operation.Read moreRead less
