OPERATION OF A GAS TURBINE PLANT HAVING A COMPRESSOR AND A TURBINE

摘要

A method for operating a gas turbine plant having a compressor and a turbine, where a limit value of a guide blade adjustment for the compressor of the gas turbine is identified depending on at least one drive shaft speed of the gas turbine plant. For the at least one drive shaft speed, a maximum allowable turbine entry temperature corresponding to the limit value of the guide vane adjustment for the compressor or a maximum allowable temperature for the turbine of the gas turbine, which is dependent on the turbine entry temperature, is identified. The gas turbine is operated in consideration of the identified maximum allowable turbine entry temperature or the identified maximum allowable temperature.

1. A method for operating a gas turbine plant having a compressor and a turbine, the method comprising:
in dependence on at least one drive shaft speed of the gas turbine plant,
identifying a limit value of a guide blade adjustment for the compressor of the gas turbine and for the at least one drive shaft speed
identifying a maximum allowable turbine entry temperature corresponding to the limit value of the guide blade adjustment for the compressor or a maximum allowable temperature dependent on the turbine entry temperature for the turbine of the gas turbine, and operating the gas turbine taking into account the identified maximum allowable turbine entry temperature or the identified maximum allowable temperature.
