A Compact, High Capacity 330kV Substation for the Sydney Central Business District

摘要

Sydney has a population of over 4 million people with approximately 1 million living in the inner suburbs and Central Business District (CBD). The strong population growth and changing demographics of the city of Sydney has lead to a growth in demand for electricity. A major infrastructure project is being constructed to meet this demand. A critical component of this project is the new Haymarket Substation located close to the CBD.Bringing a high capacity connection at transmission voltage close to the CBD distribution network and its load has presented challenges in the design of the substation and its component parts so as to address the issues of environmental impacts and public safety in the inner city environs.This paper describes the particular innovative building design solutions and extensive systems monitoring adopted for the Haymarket Substation to address these challenges and how these innovations have been effectively coupled with proven high voltage plant designs.
