Title:
ELECTRIC POWER GENERATION PLANT, STEAM COOLING SYSTEM AND CONTROL DEVICE AND CONTROL METHOD THEREFOR
Document Type and Number:
Japanese Patent JP2023132696
Kind Code:
A
Abstract:
To control a cooling water flow volume to a proper range.SOLUTION: A steam cooling system comprises a first adjusting valve for adjusting the flow volume of cooling water to be supplied from a cooling tower to a condenser, and a second adjusting valve for adjusting the flow volume of warm water to be supplied from the condenser to the cooling tower. A control device comprises a measurement value acquisition portion 51 acquiring a measurement value of a parameter related to the steam cooling system including differential pressure ΔPcg between atmospheric pressure and condenser pressure which is pressure of an internal space of the condenser, and a calculation portion 52 calculating the opening Z1 of the first adjusting valve on the basis of information for calculating the opening Z1 of the first adjusting valve, wherein the opening Z2 of the second adjusting valve is a target value of the opening Z1, from the parameter related to the steam cooling system, and the measurement value acquired by the measurement value acquisition portion 51.SELECTED DRAWING: Figure 4
