    摘要： Systems and methods for improving the efficiency of a power generation facility utilize heat energy to preheat inlet-air that is supplied to the compressor of a turbine or to preheat fuel that is burned in the turbine. The heat energy used to preheat the inlet-air can be drawn from a heat recovery steam generator (HRSG) that produces steam using at least part of the exhaust gas of the turbine. The heat energy can be obtained from one or more predetermined points within the HRSG, such as a feed water line exiting a drum of the HRSG or a feed line connecting an economizer of the HRSG to a drum of the HRSG. The fluid drawn from the predetermined point passes through a heat exchanger or a preheater to remove the heat energy used for preheating. The fluid is then returned to the HRSG immediately downstream from the point from which it was drawn.

    摘要： A control system (200) for a power plant includes a sensor (202) that measures a rotor surface temperature of a steam turbine rotor, where the temperature is a function of exhaust gasses from a heat source (214) for heating steam to a target temperature. The control system includes a controller (204) coupled to the sensor (202) and configured to compute the target temperature using an inverse process model (210) for steam turbine rotor stress dynamics, and based on a reference steam turbine rotor stress and a feedback steam turbine rotor stress, compute a measured steam turbine rotor stress based on a measured surface temperature of the steam turbine rotor, compute an estimated steam turbine rotor stress using a process model (208) for the steam turbine rotor stress dynamics, and based on the target temperature, and compute the feedback steam turbine rotor stress based on the measured steam turbine rotor stress and the estimated steam turbine rotor stress.

    摘要： A number of exemplary power generation systems and methods are disclosed herein. In some embodiments, a compressed air energy storage system, optionally with split-cycle engine technology, is used to store energy obtained from the grid during off-peak hours and to supply stored energy to the grid and/or to an end user during on-peak hours. The system can include heat recovery features and can supply heat to the end user. In some embodiments, a generator system is used to provide power to an end user and to the grid. The generator can be maintained in a high efficiency operating range (e.g., at elevated or full load), even when the generator output exceeds the end user's demand, with any excess generated power being fed to the grid.

    摘要： A method is provided for calibrating an active clearance control system (60) for a plurality of turbine engines (20). During this method, a squeeze test (500) is performed between a tip (66) of a rotor blade (68) and a shroud (64). Results of the squeeze test are applied to adjust a gap (62) between the tip and the shroud. The performance of the squeeze test and the application of the results are individually performed for each of the turbine engines. The active clearance control system includes an actuation system (70) and a controller (80) and is operable for recalibration based on the performance of another squeeze test.
