Abstract
PURPOSE: To perform stable control of water feed in a turbine driving a feed water pump, by performing correction control of opening of a control valve correspondingly to one of the data of driving steam pressure, load demand signal and main turbine load.
CONSTITUTION: Extraction steam of a main turbine 4 is fed through a low pressure control valve 3 to drive a feed water pump driving turbine 2. In accordance with a boiler feed water flow rate signal 6, feed water pump flow rate signal 7, speed signal 8 of the turbine 2 further driving steam pressure 9 and load demand signal, arithmetic operation is performed in a feed water controller 11 to output a low pressure control valve opening command 10. An opening degree of the control valve is correctively controlled inversely in proportion to the driving steam pressure 9 or in an approximate function. In this way, an unstable state of the control valve at change of a load can be eliminated to perform stable control of feed water.
