Device and method for controlling the exhaust temperature of a gas turbine of a power plant

摘要

A method for controlling the exhaust temperature of a gas turbine (5) of a power plant (1) includes the step of regulating the position of a plurality of inlet guide vanes of a compressor (3) of the plant (1) in such a way that the exhaust temperature of the gas turbine is equal to a reference value (NEWSET TETC ) calculated on the basis of the actual environmental conditions (T ACT , p ACT ), on the basis of an actual power (W ACT ) delivered by the plant (1) and on the basis of a first reference base power (W BASE ISO ) in standard environmental conditions.
