STEAM TEMPERATURE CONTROL DEVICE, STEAM TEMPERATURE CONTROL METHOD, AND POWER GENERATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a steam temperature control device capable of preventing a steam temperature from being made excessively high with change of state of a superheater provided at the downstream side of a desuperheater.SOLUTION: A steam temperature control device according to one embodiment includes: a reception unit that receives one or more first measurement values to be a measurement value related to steam overheated by a superheater, and one or more second measurement values to be a measurement value related to a heat source of the superheater; and a control unit that controls operation of a desuperheater for supplying the steam to the superheater, on the basis of the first and second measurement values.SELECTED DRAWING: Figure 2
