Falklands Mount Pleasant Airbase
Large 11 kV Industrial Network with islanded generation
The challenge
Large islanded networks are relatively uncommon and require detailed analysis to ensure the system performs correctly across all operating conditions. Mount Pleasant Airbase is a large complex, with over 70 substations, five ring feeders and a partially closed distribution system.
What Aurora did
We built and validated an ETAP model of the 11 kV islanded network, covering the main generation sources, ring feeders and major substations. The study work included loadflow, short circuit, protection coordination and arc flash assessment across the credible operating configurations. Particular care was needed because conventional distribution assumptions do not always hold on an islanded industrial network with limited generation and variable fault contribution.
