shows the power generated or consumed by the
turbines and compressors of the plant at different degree of
supplementary firing. It is observed that at f¼ 0, the GT produces
58.4MW power, while 21.5MW is generated by the steam turbine.
The MC and AC require 21.2MWand 8.05MW, respectively, at this
operating condition. As f is increased, the power generated by the
steam turbine increases, and that by the GT correspondingly
decreases. The power consumed by the MC and AC also decreases at
higher f.
