In a method for the control and protection of a gas turbine a gas turbine performance and lifetime indicative process quantity is estimated from a set of available process signals. Said gas turbine performance and lifetime indicative process quantity is simultaneously evaluated by two different estimation methods (11, 12), whereby a first estimation method (11) has a high prediction accuracy, and a second estimation method (12) has a high availability, a continuous adaptation (14) of said second estimation method (12) is conducted in order to align the output signals (T A , T B ) of the two estimation methods, and in case of a failure (F) detected in the supervision (13) of said first estimation method (11) said adaptation (14) of said second estimation method (12) is stopped, and the output of said first estimation method (11) is switched to the output of said second estimation method (12). |
