Abstract

A combined cycle electric power generating plant, which includes gas and steam turbines, inlet guide vane positioning means for the gas turbines, steam generators, afterburners and a digital/analog control system, is provided with inlet guide vane control apparatus adapted to modulate the position of the inlet guide vanes as a function of load or inlet blade path temperature. The inlet guide vane control apparatus is further adapted to operate in either an automatic or manual mode with additional provision for bumpless transfer therebetween incorporated in the control apparatus.
