Design of generator, transformer, bus and 5kV protection for three 206MVA gas turbine generators (Units 2, 3, 4) at Fort Saint Vrain Station in North Central Colorado; design included one-lines, AC three-lines, DC schematics and relay settings; provided commissioning support to site during outage and calculations for 100% stator ground fault protection. Primary and Backup relaying for generators and generator step-up transformer (GSU). Relay settings development involved compliance with NERC/WECC standards.
