GAS TURBINE DRIVEN GENERATORS      53




























                      Figure 2.16 Control system for the speed governing of a single-shaft gas turbine.






























                      Figure 2.17 Control system for the speed governing of a two-shaft gas turbine.


           gas turbines are normally able to provide detailed mathematical models of the machines and their
           control systems.
                 The modelling of the complete gas turbine including its control system and its interaction with
           the driven generator can be divided into several main functions. See Figures 2.16 and 2.17. Figure 2.16
           represents a single-shaft gas turbine whilst Figure 2.17 represents a two-shaft machine.
