摘要： A method controls at least a portion of a combined cycle power plant having at least one gas turbine, at least one heat recovery steam generator, and at least one steam turbine. The method includes developing an actual operating curve of a steam characteristic of the at least one heat recovery steam generator versus an amount of steam provided to the at least one steam turbine from the at least one heat recovery steam generator. The method also includes determining the steam characteristic of the at least one heat recovery steam generator at a point in time during operation of the combined cycle power plant. The method further includes providing an amount of the steam from the at least one heat recovery steam generator to the at least one steam turbine depending upon the determined steam characteristic of the at least one heat recovery steam generator at the point in time.
