摘要： A coordinated air-fuel controller and associated method provide a fuel controller, a combustion air controller and a steady-state air versus fuel model. The fuel controller generates a fuel control output signal and the combustion air controller generates a combustion air control output signal. The fuel controller determines a preliminary fuel control signal based on at least one of first and second loop control signals, and determines the fuel control output signal based on the preliminary fuel control signal. The steady-state air versus fuel model processes the preliminary fuel control signal to determine an expected steady-state combustion air control signal. The combustion air controller determines a preliminary combustion air control signal based on at least one of a third loop control signal and a fourth loop control signal, and determines the combustion air control output signal based on the preliminary combustion air control signal and the expected steady-state combustion air control signal.

摘要： Systems and methods for analyzing and displaying power plant data are able to access continuous live and/or historical operational data and identify within the data: (a) instances of at least one given type of power plant operation, (b) key events that may occur during an instance of the at least one given type of power plant operation, and (c) one or more time-based segments based on the key events and a physical segmentation of the power plant. Performance aspects for selected identified power plant operation instances can be quantified by comparing the identified instances with metrics that are predefined relative to the key events and segmentation within each type of power plant operation. Selected data associated with the identified instances are provided as electronic output to a user.

摘要： A fuel controller, and associated method, provides a fuel control output signal to a fuel control actuator to control operations. The fuel controller determines the fuel control output signal based on rotational speed error. A combustion air controller provides a combustion air control output signal to a combustion air control actuator to control operations. A cross channel controller is in communication with the fuel controller and the combustion air controller. The cross channel controller provides a combustion air control modification signal to the combustion air controller. The combustion air control modification signal is determined from the fuel control output signal using an air versus fuel model. The combustion air controller determines a preliminary combustion air control signal based on an exhaust temperature error, and further determines the combustion air control output signal based on both of the preliminary combustion air control signal and the combustion air control modification signal.

摘要： A system and method for data exchange is provided. In one embodiment, a processor is configured to handle a data packet that represents a physical attribute related to monitoring and/or control of at least one equipment over a period of time.
