Method of controlling a power generation system
A method of controlling a gas turbine system ( 10 ) may include controlling an inlet guide vane position ( 98 ) to maintain a turbine ( 24 ) exhaust temperature at a corrected value that is a function of a compressor ( 12 ) inlet temperature and a turbine ( 24 ) normalized load. The method may inclu...

| description | A method of controlling a gas turbine system ( 10 ) may include controlling an inlet guide vane position ( 98 ) to maintain a turbine ( 24 ) exhaust temperature at a corrected value that is a function of a compressor ( 12 ) inlet temperature and a turbine ( 24 ) normalized load. The method may include selecting the minimum value ( 138 ) of a part load tunable value, a part load maximum value and a fixed maximum value of a turbine ( 24 ) exhaust temperature for the corrected value. A corrected value setpoint may be determined ( 94 ) for the gas turbine system ( 10 ) operating at a part load condition where at least one of a fuel flow rate and the inlet guide vane position is controlled ( 98 ) so the corrected value does not exceed the corrected value setpoint. The corrected value may prevent a turbine ( 24 ) engine from exceeding its firing temperature during operation and ensure the engine operates within combustor dynamics and emissions limits. |
