Abstract
A method and a system for limiting steam flow entering a steam turbine are provided. The method and system may intentionally unbalance the steam flow apportioned between sections of the steam turbine. The steam turbine comprises at least: a first section, a second section, and a rotor disposed within each section. The method may receive a speed/load command, or the like, which provides reference strokes for a first valve, associated with the first section; and a second valve, associated with the second section. The method may also determine an operational parameter that may limit the reference strokes relative to the speed/load command. The operational parameter may determine the allowable steam flow for each section of steam turbine, independent of the speed/load command.
