Abstract

PURPOSE:To enable three element control method by detecting feed water heater outlet temperature and reactor purification outlet temperature system, reactor purification system outlet flow, and the temperature of said mixed water and computing pseudo feed water flow necessary for control. CONSTITUTION:A feed water heater outlet temperature signal a 17a, a reactor purification system outlet temperature signal 18a, a temperature signal 20a after mixing the reactor purification system and the feed water are converted into enthalpy by the use of function generators 32, 33, 34 respectively, operation corresponding to an equation with a reactor purification system flow 19a is performed, a low flow feed water regulating valve opening signal 11a is input into a gain regulator 24 and to add said output signal as correction quantity becomes a pseudo feed water flow signal 28. A deviation signal between a steam drum water level detector 16 and a water level setter 25 is applied on the basis of a pseudo feed water flow signal 28 and a pseudo steam flow signal 27 obtained thereby, a low flow feed water regulating valve 11 is controlled through a water level controller 26.
