abstract

This paper presents an analysis of the influence of control logic on gas turbine operation, when machine load adjustments are carried out.

An examination is made of the control logics that are possible for a two-shaft gas turbine with variable power turbine nozzle in order to reach the following objectives:

- operation in maximum efficiency conditions;

- operation in the conditions of maximum thermal power of exhaust gases at the turbine outlet;

- operation at constant turbine outlet temperature;

- operation with the maximum Surge Margin.

The control logics necessary for reaching the predetermined objectives in the part-load operation are provided by the map of gas turbine’s main performance, thermodynamic and control parameters.
