A CONTROL DEVICE AND METHOD OF A GAS TURBINE ELECTRIC ENERGY PRODUCTION PLANT

摘要

A control device of a gas turbine electric energy production plant (1), which delivers a power (P) at a frequency (f <SUB>I</SUB>) presents power control means (15) for controlling the power (P) delivered by the plant according to a reference power value (P<SUB>SETNEW</SUB>), and frequency control means (16), for determining correction values (PF<SUB>SETPR</SUB>; PF<SUB>SETINT</SUB>) of the reference power value (P<SUB>SETNEW</SUB>) according to a frequency error (e<SUB>F</SUB>), given by the difference between the plant frequency (f<SUB>I</SUB>) and a nominal frequency (f<SUB>N</SUB>), which comprise integral control means (22) configured to calculate the correction values (PF<SUB>SETINT</SUB>) and selectively activatable when the frequency error (e<SUB>F</SUB>) is beyond a first frequency range (B1).
