ABSTRACT:
South Australian power system is heavily dominated by inverter-based resources. Maintaining the stability of such a power system is always challenging. This system is interconnected with the Victoria AC system with a 275 kV AC interconnector. At present, another interconnector is being planned to connect the South Australia system with the New South Walse system. Studies have revealed that a trip of these interconnectors can create stability risks to the South Australian network. To mitigate these risks, EneltraNet is developing a wide area protection scheme. This presentation will discuss the development of a wide-area network model in RTDS to perform the HIL testing of this wide-area protection scheme. The presentation will include the following:
· A description of the need for this protection scheme
· Model development methodology
· Challenges encountered during the model development
· The test plan requirements incorporated
