Popis: A 735MW Combined Cycle Gas Turbine (CCGT) site comprising of three generating units is used as a case study in this paper. The two gas turbines and one steam turbine site was commissioned in 1995. Each of the three generating units has a dedicated 290MVA 420/15kV GSU transformer, while two of the generating units are interfaced to a dedicated 12/21.5MVA, 15/3.3/3.3kV unit transformer.
