Abstract (en)
[origin: EP3757355A1] The objective of the present invention is to provide a technique for controlling a steam governing valve of a power generation plant capable of maintaining an active power output after recovery from a power system transient event. A control system (10) for a steam governing valve of a power generation plant is provided with a transient event detecting unit (48) which detects an occurrence of a power system transient event, and an opening degree correcting unit (110) which, during the occurrence of the power system transient event, maintains an opening degree of a steam governing valve (13) for adjusting an amount of steam flowing into a steam turbine (18) to be in the vicinity the opening degree when the power system transient event occurred.
