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., combustion temperature) to manage combustion gas contents exiting from the combustor, controlling compressor bleed valve(s) to control the combustion temperature, controlling the catalyst assembly to process exhaust gases to be released into the environment, or a combination thereof.

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.
