CORRECTED PARAMETER CONTROL METHOD FOR A TWO-SHAFT GAS TURBINE |
摘要 |
<p>A corrected parameter control method for a two-shaft gas turbine, of the type in which the protection of the said turbine is provided by a first control loop which controls the opening of fuel valves to keep the gas temperature Tfire at the inlet to a first wheel of the said turbine and the fuel/air ratio F/A within specified limits: this control is provided in such a way that the exhaust temperature TX has values calculated by a linear approximation, in other words as the sum of a reference temperature TXbase to which are added corrections relating to a single environmental or operating parameter which differs from the reference parameter; a second control loop, which controls the opening of a valve (bleed valve) located between the outlet of the axial compressor and the atmosphere, controls the F/A ratio: this control is provided in such a way that the exhaust temperature has values calculated by a linear approximation.</p> |
