Abstract (en)

[origin: EP2239641A2] A device (21) for determining operating parameters of a gas-turbine plant (1) is provided with a first calculating module (26), for calculating a reference exhaust temperature (TRIF) of the turbine (12) on the basis of an ambient temperature (TA), and a second calculating module (27), for calculating a pilot-gas flowrate (QP) to be supplied to a combustion chamber (11) of the plant (1) on the basis of a current exhaust temperature (TS) of the turbine (12) and on the basis of a current position (IGV%) of adjustable inlet guide vanes of a compressor (10) of the plant (1). The first calculating module (26) has a first operating mode and a second operating mode, and the second calculating module (27) has a first operating mode, a second operating mode, and a third operating mode. The device (21) is moreover provided with configuration means (30a, 30b, 30c, 32) for selecting one between the first and second operating modes of the first calculating module (26) and one from among the first, second, and third operating modes of the second calculating module (27).
