Abstract: A water delivery system for a gas turbine compressor having a plurality of blade stages positioned about a rotating shaft is provided. The plurality of blade stages are configured to compress an airflow. The water delivery system includes a nozzle system to inject water between at least one pair of the plurality of blade stages; and a controller controlling whether the water injected by the nozzle system is injected at a first pressure that augments power output during an operation mode of the plurality of blade stages and a second, lower pressure that washes at least some of blades of the plurality of blade stages during a wash mode of the plurality of blade stages.

Abstract: In one aspect the present subject matter is directed to a system for cooling a turbine engine. The system includes a cooling medium source, a stator vane having an internal flow passage that is in fluid communication with the cooling medium source and a turbine shroud assembly having an internal flow passage that is in fluid communication with the internal flow passage of the stator vane. The system allows for reduced peak thermal gradients between a cooling medium provided by the cooling medium source and various turbine hardware components such as the turbine shroud assembly.

Abstract: Exciter circuitry includes a controller that receives a first signal requesting that a generator coupled to the exciter circuitry stop providing real power to an electrical grid. The controller also sends a second signal to a turbine control system of a turbine coupled to the generator to close at least one fuel nozzle, at least one inlet guide vane, or at least one variable stator vane in response to receiving the first signal. The controller further instructs the exciter circuitry to provide direct current (DC) voltage and DC current to a rotor of the generator, wherein the DC voltage and the DC current causes the generator to operate synchronously with the electrical grid.
