Project #1423

PV Project 1.0 MW AC, Stearns County, Minnesota facility electrical distribution system consists of a simple radial distribution arrangement through a main switchgear. The main switchgear is fed from Xcel Energy utility connection through 1MVA 12.47/0.48kV transformer and twenty (20) 55 kVA solar inverters. The references used to conduct the study are National Fire Protection Association, NFPA-70E and NFPA-70 and Institute of Electrical and Electronics Engineers, IEEE-1584-2018, IEEE-141, IEEE-214, IEEE-242, IEEE-399 and IEEE-551. This report contains the results of the photo-voltaic system Power System Analysis that consisted of a Short Circuit Study, Equipment and Device Evaluation Study, Protective Device Coordination Study and Arc Flash Hazard Analysis
