Stockyard Hill Wind Farm

132kV, 2 x ±15Mvar

The Stockyard Hill Wind Farm is located in Victoria, Australia and comprises of 149
wind turbine generators. This contract was the second to be awarded to RXHK in the
Australian market in 2018/2019. The STATCOM and harmonic filter equipment was
all delivered, installed and cold commissioned within the required very demanding
timeframe, with the energised commissioning aligned with the overall substation site
commissioning.

The RXHK design and supply contract was for eight off ±8Mvar 11kV water-cooled
STATCOM with 2.7x short-term overload capability, along with the supply of five
25Mvar 33kV C-type harmonic filters for the overall windfarm harmonic performance
and reactive support. A key part of this project was for RXHK experts to work as part
of a joint modelling team to help verify the overarching voltage control scheme as part
of meeting the demanding AEMO and GPS requirements. This included the delivery
of AEMO compliant PSSE and PSCAD models of the STATCOM equipment as well as
support of the site model verification activities.

The STATCOM equipment supplied has been designed to be installed and operated
in accordance with the local Australian environment and conditions, and in
compliance with AS, IEC and local regulations and standards.

At RXHK we are proud to be simultaneously supporting Australia to reach its climate
change goals and keeping the electricity system stable and efficient through the
delivery of efficient, robust and cost effective solutions.
