The feed water control system null steam generator to the steam generator in

摘要

PROBLEM TO BE SOLVED: To provide stability of a water level of a steam generator, and stability of a flow rate balance between a steam flow rate and a feed water flow rate of each turbine plant in feed water control for the steam generator in a power generation plant composed by combining the steam generator and a plurality of turbine plants.;SOLUTION: In the power generation plant composed by combining the steam generator 1 and the plurality of turbine plants 100 and 200, control in a feed water controller 5 of the first turbine plant (the main turbine plant) 100 is carried out by normal control, namely, control of a feed water flow regulating valve 6 by using detection signals of a steam generator water level detector 7, a main steam flow rate detector 8, and a feed water flow rate detector 9 of the first turbine plant 100, and control in a feed water controller 15 of the second turbine plant (the sub turbine plant) is carried out by control of a feed water flow regulating valve 16 by using a detection signal of a condenser water level detector 10 of the first turbine plant.;COPYRIGHT: (C)2006,JPO&NCIPI
