Gas Turbine and Electric Generator Controls

The control of steam turbines will be discussed separately in Section 2.19. Therefore, here the focus will be on the optimization of gas turbine (GT) operation. The GT system consists of three main parts the air compressor (axial type), the burners, and the turbine itself. The mechanical power gener- 

In the single-shaft arrangement, there is only one electric generator, driven by both the gas turbine and the steam turbine. This means that the electric power plant is simpler, because there is only one step-up transformer and one bay to connect to the grid. 

Single-shaft power plant configurations can locate the gas turbine and the electric generator at the two ends of the shaft (top) or can locate the steam and gas turbines at the two ends (bottom).

When the plant is located in built-up areas, there might also be an atmospheric condenser that receives the steam, which is vented during the startup to decrease the noise level at the plant. The auxiliary circuits of the steam turbine are the lube oil, control fluid, and vacuum system for the condenser.
