ABSTRACT:
In order to limit the flame temperature peaks following sudden load variations, corresponding control is planned of the position of the blades (13) of the distributor with variable geometry, of a single-shaft gas turbine (18); in particular, the control system proposed comprises a direct-action regulator (21) consisting of a calculation unit (22), which implements the simplified running model of the gas turbine (18), and a feedback regulator (20), which makes it possible to recuperate any inaccuracies of the direct-action regulator (21), caused by variations of the performance of the turbine (18), relative to those planned by the model, or caused by modelling errors.
