摘要： Systems and methods of estimating an efficiency of a section of a steam turbine are disclosed. The systems and methods include determining a set of measurement data obtained directly from a set of sensors on the steam turbine, determining a set of derived data relating to measurements that cannot be obtained directly from the set of sensors, and estimating the efficiency of the section using the set of measurement data and the set of derived data. The systems and methods disclosed use physics-based models combined with nonlinear filtering techniques to estimate steam turbines' efficiencies when physical sensors are not available. These models capture the behavior of different components of the power plant, including all steam turbine sections, admission and crossover pipes, flow junctions, admission and control valves.

摘要： A control system for a combined cycle power generation system including a gas turbine engine (GT), a heat recovery steam generator (HRSG), and a steam turbine (ST) includes a display wherein an operator may observe information about predicted operating parameters; a user interface wherein an operator may provide additional operating constraints; and a controller configured to generate input profiles of the GT, the HRSG, and the ST that satisfy the nominal constraints and any additional constraints and to generate the information about the predicted operating parameters. The controller may be configured to detect a stage transition of power generation system operation and update the input profiles. The controller may be configured to generate alternative operating scenarios by mapping alternative control actions to an operating constraint of at least one of the system components.

摘要： A method of operating a steam turbine in a combined-cycle power system is provided. The method includes channeling a first amount of steam from a first steam generator to the steam turbine to facilitate powering the steam turbine, generating a second amount of steam within a second steam generator that is coupled in flow communication with the steam turbine, and calculating a predicted stress level within the steam turbine in the event the second amount of steam is channeled from the second steam generator into the steam turbine. An initiation time at which to channel the second amount of steam into the steam turbine is determined such that the calculated predicted stress level will not exceed a predetermined stress limit of the steam turbine. The second amount of steam is automatically channeled from the second steam generator to the steam turbine at the determined initiation time.
