Abstract
PURPOSE: To permit of quick starting and rapid load variation, by obtaining a new variation width on the basis of weighted averaging at a predetermined ratio to the ratio between the variation widths of an inlet steam condition before and after restriction and predicting the future variation in the turbine inlet condition and limiting the stress of rotor below an allowable level.
