    摘要: A method (400) for increasing the operational flexibility of a turbomachine during a shutdown phase is provided. The turbomachine may include a first section, a second section, and a rotor disposed within the first section and the second section. The method (400) may determine an allowable range of a physical parameter associated with the first section (440) and/or the second section (460). The method (400) may modulate a first valve (450) and/or a second valve (470) to allow steam flow into the first section and the second section respectively, wherein the modulation is based on the allowable range of the physical parameter. In addition, the physical parameter allows the method to independently apportion steam flow between the first section and the second section of the turbomachine, during the shutdown phase.

    摘要: A method and a system (100) for limiting steam flow entering a steam turbine (102) are provided. The method and system (100) may intentionally unbalance the steam flow apportioned between sections (110,112) of the steam turbine (102). The steam turbine (102) comprises at least: a first section (112), a second section (114), and a rotor (115) disposed within each section. The method may receive a speed/load command, or the like, which provides reference strokes for a first valve (116), associated with the first section (110); and a second valve (118), associated with the second section (112). 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 (102), independent of the speed/load command.
