Patent ID: 8621840

Claim:
A control device of a gas turbine electric energy production plant ( 1 ), which delivers a power (P) at a frequency (f 1 ); the control device ( 8 ) comprising power control means ( 15 ), for controlling the power (P) delivered by the plant ( 1 ) according to a reference power value (P SETNEW ), and frequency control means ( 16 ), for determining correction values (PF SETPR ; PF SETINT ) of the reference power value (P SETNEW ) according to a frequency error (e F ), given by the difference between the plant frequency (f 1 ) and a nominal frequency (f N ); the device ( 8 ) being characterized in that the frequency control means ( 16 ) comprise integral control means ( 22 ) configured to calculate the correction values (PF SETINT ) if the frequency error (eF) is beyond a first frequency range (B1) and proportional control means ( 20 ), which are deactivated when the frequency error (eF) is beyond the first frequency range (B1).
