A regulating device for regulating the course of a gas turbine plant (1) has at least one sensor (21, 23, 25, 27, 35, 37) for sensing a measurement variable and for outputting a measurement signal which represents the measurement variable; at least one adjusting system (31, 32) for influencing air and/or fuel supply to a combustion chamber (12) of the gas turbine plant on the basis of a correcting variable; and a regulator (29) connected to the at least one sensor (21, 23, 25, 27, 35, 37) so as to receive the measurement variable and to the at least one adjusting system (31, 32) for outputting the correcting variable, the regulator (29) being designed to determine the correcting variable on the basis of the measurement variable received and its deviation from a pilot variable. At least one sensor (21, 23, 25, 27, 35, 37) is designed to sense the variation in time of at least one burner or combustion chamber parameter as measurement variable.

L'invention concerne un dispositif de régulation servant à réguler le fonctionnement d'une installation de turbine à gaz (1), lequel dispositif comprend au moins un capteur (21, 23, 25, 27, 35, 37), prévu pour acquérir une grandeur de mesure et délivrer un signal de mesure représentant la grandeur mesurée, au moins un dispositif de réglage (31, 32), destiné à influer sur l'alimentation en air et/ou en combustible d'une chambre de combustion (12) de l'installation de turbine à gaz sur la base d'une grandeur de réglage, ainsi qu'un régulateur (29) relié audit au moins un capteur (21, 23, 25, 27, 35, 37) pour recevoir la grandeur de mesure et audit au moins un dispositif de réglage (31, 32) pour délivrer la grandeur de réglage, lequel régulateur est conçu pour déterminer la grandeur de réglage à partir de la grandeur de mesure reçue et son écart par rapport à une grandeur de référence. Selon ladite invention, au moins un capteur (21, 23, 25, 27, 35, 37) est destiné à détecter la variation temporelle d'au moins un paramètre de brûleur ou de chambre de combustion comme grandeur de mesure.
