AC and DC Arc Flash Methods for Renewable Energy Systems

This presentation will address the difficulties and lessons learnt on performing arc flash analysis using available methods (outside the voltage limits of IEEE 1584-2018 standard) on a 2.3 MW PV generation facility. The analysis includes system modeling, short-circuit, arc flash (both AC and DC) using various applicable calculation methods that best fit this application along with available tools in ETAP and generating worst-case arc flash deliverables.
