Document Type and Number:
WIPO Patent Application WO/2017/145427
Kind Code:
A1
Abstract:
A control device (100) comprises: a reception unit (101) which receives a load schedule (LS) indicating a future load of a combined cycle plant; a steam temperature control unit (103) which controls the temperature of steam that flows into a steam turbine (30); and a fuel control unit (104) which controls a flow rate of fuel supplied to a gas turbine 10. The steam temperature control unit (103) outputs a command to a steam temperature adjusting device (26, 28) prior to a load decrease time at which the load is to be reduced according to the load schedule (LS), the command indicating a manipulated variable which causes the steam temperature to decrease.
