Review of Design, Grid Protection, Compliance Assessment
Design Phase – Jan 2013 – July 2013
Construction Phase – Oct 2013 – Feb 2014
To review the Belectric standard PV design template for ground mount installations and adapt to ensure compliance with Australian Standards and conditions as well as the local DNSP’s requirements.
The site is over 20km from the nearest substation. Voltage issues on the network initially limited the system size to 2.5MW. Through a detailed Network Technical Study, CTP designed a power factor control strategy that facilitated an additional 1MW of capacity.
- Successfully adapted the system to comply with relevant Australian standards. Australia is one of the first countries in the world to implement a specific engineering standard that deals with DC side of a PV system (AS5033).
- Determined grid protection and SCADA requirements of Powercor, the local DNSP, in order to design the grid-connection station. This required the development of a PSS Sincal network simulation model to determine thermal capacity, voltage and power factor impacts on the local electricity grid.
- CTP oversaw the construction and installation of the grid-connection station (see Utility PV Solutions for further details). This was successfully commissioned allowing the safe operation of the PV generation in parallel with the grid.
- System cost was analysed alongside risk, efficiency and a detailed supplier and product evaluation against shortlisted options in order to finalise the system design and specification.
- The system was the largest sized PV plant connected to the Powercor network at the time of commissioning.
