A CONTROL DEVICE AND METHOD OF A GAS TURBINE ELECTRIC ENERGY PRODUCTION PLANT |
摘要 |
<p>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 (1) by means of a first control signal (U<SUB>?P</SUB>) which determines the supply of fuel to a portion (11) of the plant (1) according to a reference power value (P<SUB>SETNEW</SUB>), and frequency control means (16), for determining correction values (P<SUB>FSET</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 step control means (22) configured to adjust the supply of fuel to the portion (11) of the plant (1) by means of a second control signal (U<SUB>STEP</SUB>) concurrent with the first control signal (U<SUB>?P</SUB>), when the derivative of the frequency (f<SUB>I</SUB>) of the plant (1) assumes values higher than a threshold value (S).</p> |
