Title:
POWER GENERATION PLANT, STEAM COOLING SYSTEM, DEVICE FOR CONTROLLING SAME, AND METHOD FOR CONTROLLING SAME
Document Type and Number:
WIPO Patent Application WO/2023/171244
Kind Code:
A1
Abstract:
The present invention controls a cooling water flow rate so that the cooling water flow rate is within an appropriate range. Provided is a steam cooling system comprising a first regulator valve for regulating the flow rate of cooling water supplied from a cooling tower to a condenser and a second regulator valve for regulating the flow rate of hot water supplied from the condenser to the cooling tower. The control device comprises: a measurement value acquisition unit (51) that acquires measurement values of parameters which are related to the steam cooling system and include a differential pressure (ΔPcg) between the atmospheric pressure and a condenser pressure, which is the pressure in an interior space of the condenser; and a calculation unit (52) that calculates an opening degree (Z1) of the first regulator valve on the basis of information for calculating, from the parameters related to the steam cooling system, the opening degree (Z1) of the first regulator valve having an opening degree (Z2) of the second regulator valve as a target value and the measurement values acquired by the measurement value acquisition unit 51.
