Padcon and Jurchen Technology are capturing the Australian market: Padcon is providing the technology required to monitor and control Australia's solar power plant. Jurchen Technology is supplying the DC wiring system for the solar power plant. A total of around 80,000 metres of cable and about 40,000 solar plugs are being installed.
"We monitor PV plants with more than three gigawatts of installed capacity for customers all over the world", says Constantin Wenzlik, CEO of Padcon GmbH. "Limondale is another major project we have added to our portfolio. For this project alone, we can capture around 24,000 plant parameters, which will not only help control but also protect the entire plant."
The Limondale solar power plant of innogy SE is currently being built in Balranald, New South Wales. When completed, it will have an installed capacity of 349MW. Start of full commercial operation is anticipated to be mid-2020. Capture of the individual performance parameters occurs via 58 decentralised data loggers which in turn communicate with a central SCADA unit. As well as data collection, processing and alarm functions, this server rack solution features a redundant back-up system and an onsite human-machine interface – or an operator interface which gives on-site operating and maintenance teams access to the plant's live data. Remote control of the plant and 1st/2nd tier support is provided by the Padcon Control Centre. Thanks to their 24/7 operation, plants like these can be monitored worldwide and in all time zones from the company's base in the Lower Franconian town of Kitzingen (Bavaria), while local teams receive on-site support.
Although there are no legal guidelines in Australia yet for how well PV power plants of this magnitude need to be protected from cyberattacks, innogy is drawing on Padcon's expertise for Limondale and has opted for a state-of-the-art cyber security concept. "PV plants are generally well protected from burglary and theft. But a further and probably greater threat is the kind that lurks online", says Constantin Wenzlik. "This means cyber security is something that needs to be built into all projects from the very start, and at all levels – the PV plant, data centre and, of course, at the user level too."
"What drives up the construction costs of a photovoltaic power plant? In a nutshell, it is a combination of the construction period, the material costs and the use of machinery. In developing the PEG substructure, we optimised all three of these factors. The result is a simple and unique solution – which is not just in high demand with customers in Australia", says Michael Jurchen, CEO of Jurchen Technology GmbH.
As Michael Jurchen explains: "It is no surprise that more and more Australian customers are opting for this innovative substructure. For all the benefits of this system really come into their own in Australia."
"With this PEG substructure we can significantly reduce the overall costs – by over 40 percent in terms of the investment costs and 20 percent in terms of the running costs", says Michael Jurchen.
