<P>PROBLEM TO BE SOLVED: To provide a method for controlling a water level of a drum (34) of a heat recovery steam generation system (12) for a combined cycle power plant (10). <P>SOLUTION: The method includes a step for determining an optimum drum water level during the start-up operation of the heat recovery steam generation system (12) based on a characteristic chart model (100). The characteristic chart model (100) is generated based on a plurality of vapor pressure of the drum (34) and a plurality of temperatures of drum metal at the time of the start-up operation of the heat recovery steam generation system (12). <P>COPYRIGHT: (C)2012,JPO&INPIT |
