  • Patent number: 11898502
    Abstract: Combustion turbine control systems are configured to operate combustion turbine systems in partial or no load while meeting emission targets. The combustion turbine system includes a combustion turbine, an electrical generator, a combustion turbine controller, a catalyst assembly, and/or other relevant equipment. Based on given operating constraints, such as load conditions and emission regulations, the combustion turbine controller may execute corresponding actions to control certain gas concentrations and/or gas mass flows in the exhaust gases in compliance with emission regulations. The corresponding actions may include, but are not limited to: controlling fuel and/or diluent injection(s) to combustor(s) to control combustion (e.g.

  • Patent number: 11063539
    Abstract: This application provides methods and systems for rapid load support for grid frequency transient events. Example systems may include a turbine having a first controller, a generator coupled to the turbine, where the generator is configured to provide power to an electrical grid, and an exciter configured to provide a magnetic field in the generator. The exciter may include a second controller configured to monitor a first set of electrical properties associated with the electrical grid, determine that a transient event is present on the electrical grid based on the first set of electrical properties, and send a notification of the transient event to the first controller.

  • Patent number: 8463451
    Abstract: Systems and methods for monitoring power generation are provided. For example, such a system may include a gas turbine, an electrical generator coupled to the drive, a controller coupled to the gas turbine, and a compliance monitor. The gas turbine may generate a torque, and the electrical generator may provide power to a power grid based on the torque. The controller may cause the gas turbine to vary the torque in response to a frequency disturbance occurring on the power grid. The compliance monitor may determine whether the response to the frequency disturbance complies with a specification for the response.
