ABSTRACT:
A gas turbine control system with a control signal generator for a two-shaft gas turbine having a compressor turbine and a power turbine. The gas turbine control system comprises, in combination, a control signal generator for outputting signals for giving optimum fuel supply rates to the fuel control valve in accordance with gas generator shaft speeds of the compressor turbine until the power turbine speed approaches a target power turbine speed, so that the turbine system can be controlled under direct control conditions, a comparator for outputting a signal to switch the system from direct control to feedback control when the signal level under the feedback control becomes smaller than that under the direct control, and a selector for selecting one of the above-mentioned two control conditions, in addition to a conventional feedback control system having a power turbine differential speed detector and an calculation unit.
