This full fidelity simulator represents a combined-cycle plant, consisting of two gas turbine generators (GT), two Heat Recovery Steam Generators (HRSG), and one steam turbine generator (ST). Each gas turbine generator (GT) exhausts into a HRSG to form two independent GT/HRSG trains. Steam generated by the hot GT exhaust gases flowing through each HRSG is routed to the unit's steam turbine generator (ST). The ST exhausts into a surface condenser, and the condensate from the condenser hotwell is returned to the HRSG's. An open loop circulating water system, complete with cooling towers, removes the heat from the condenser and rejects the heat to atmosphere.
