Abstract: A system for discharging compressed air from a compressor includes a air distribution manifold that is in fluid communication with the compressor via a conduit and at least one discharge line that is in fluid communication with the air distribution manifold. The discharge line defines a flow path from the air distribution manifold to atmosphere. The discharge line comprises a coupling pipe that is coupled to the air distribution manifold, a sparger section that is disposed downstream from the coupling pipe and at least one restrictor plate that is disposed between the coupling pipe and the sparger section within the flow path. The restrictor plate comprises at least one aperture that provides a pressure drop of the compressed air between the air distribution manifold and the sparger section.

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.

Abstract: In one embodiment, a turbine system includes a compressor, an intake section including a filter house and an inlet duct. The intake section is coupled to the compressor, and the filter house is upstream from the inlet duct. The turbine system also includes one or more sensors disposed in the intake section, and a processor configured to receive sensor data from the one or more sensors, one or more filter degradation rates for one or more filtration stages of the filter house, or some combination thereof, predict a compressor degradation rate for the compressor using a compressor degradation prediction model that provides a function of performance of the compressor based on the sensor data, the one or more filter degradation rates, or some combination thereof, and perform one or more preventative actions based on the compressor degradation rate prediction.
