Strategic planning for the upgrade of the power system in Nhulunbuy
conference contributionposted on 06.12.2017, 00:00 by B Black, Nasser Hosseinzadeh
The power distribution system servicing the town of Nhulunbuy has undergone limited upgrade since the completion of the town in 1971. As a consequence a large number of key system components are operating close to their capacity limits. The issue is further amplified by major expansion of accommodation facilities within the town. This paper discusses the long term load forecast of this distribution system and proposes two options for upgrade of the system to ensure continuing security of supply. Currently there is monitoring of the condition of the system through regular load and protection surveys, however whilst these reports identify key issues with the system the recommendations are difficult to incorporate into the budgeting process as they indicate the current state of the system only, providing no opportunity for planning of upgrades. The desired outcome of this project is to provide an overview of the system improvement required as the town demand increases. This plan will also develop options for the improvement of current system limitations.
