METHOD AND DEVICE FOR CLOSED-LOOP CONTROL OF A STEAM TURBINE WITH A STEEM BLEED

Abstract ThE invention relates to a method for closed loop control of a steam turbine (1) with a steam bleed (21,23)for various operational tasks (BA,BB,BC)which are each characterized by the nature of the controlled variables (R1,R2)used for actuating elements (43,45)for valves (15,17,19,25,27)are derived, using a closed-loop control structure (37),from closed-loop control signals (YE,YS)of the regulators (33,35)which are used.Only a single closed-loop control structure (370 is used for all the operational tasks (BA,BB,BC)as a result of which the design of the closed-loop control is simplified ,the closed-loop control signals (YE,YS) are decoupled and a smooth changeover is achieved between the operational tasks(BA,BB,BC).
