Title:
CONDENSATE FLOW RATE CONTROL DEVICE FOR POWER-PLANT, AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2012/090778
Kind Code:
A1
Abstract:
[Problem] To provide a condensate flow rate control device and control method for a power plant that improve responsiveness to frequency fluctuations or requested load changes, that can reduce frequency fluctuations with precision, or that can improve the precision with which the output power conforms to requested load instructions. [Solution] A power plant equipped with a condensate flow rate control device (36) is provided with a deaerator (32) into which condensate generated in a condenser (26) is supplied via a deaerator water level adjustment valve (34) and into which the bleed steam from a steam turbine (18) is introduced. The condensate flow rate control device (36) has a water level adjustment means (40) for conducting condensate flow rate control. The water level adjustment means (40) adjusts the pressure in the condensate flow path from the deaerator water level adjustment valve (34) to the deaerator (32) so that input frequency fluctuations are suppressed, or so that the output value of a generator (12) conforms to input requested load changes, thereby adjusting the amount of bleed steam from the steam turbine (18).
