  • Model-based partial letdown thrust balancing
    Patent number: 9587522
    Abstract: A method, control system, and combined cycle power plant are disclosed herein, which enable balancing thrust between a high pressure (HP) section and an intermediate pressure (IP) section of an opposed flow steam turbine in a combined cycle power plant, including predicting or determining a presence or absence of a thrust imbalance between the HP section and the IP section based on steam flow, pressure, and temperature data at an HP section inlet; and based on the presence or absence of the thrust imbalance, adjusting an amount of steam that enters the HP section.
    Type: Grant
    Filed: February 6, 2014
    Date of Patent: March 7, 2017
    Assignee: General Electric Company

  • Method and system for reducing the impact on the performance of a turbomachine operating an extraction system
    Patent number: 8337139
    Abstract: A method and system for increasing the efficiency of a turbomachine having an extraction system is provided. The extraction system may have multiple extraction ports from which the working fluid of the turbomachine is extracted to meet extraction load requirements of an independent process. The method and system may enable a control system to optimally determine the which extraction ports to draw the working fluid from for meeting the extraction load requirement. The optimal location may be determined by utilizing the data on the load requirement, where the extraction load requirement may be operationally distinct from the turbomachine load.
