Abstract:
1. A system for controlling the startup of a gas turbine, the system comprising: a gas discharge component configured to discharge gas from a compressor component associated with the gas turbine; a fuel control component configured to control a fuel flow provided to a combustor component associated with the gas turbine; a drive component configured to supply a rotational force to a shaft associated with the gas turbine; and at least one control device configured to (i) direct the gas discharge component to discharge gas from the compressor component to reduce a compressor pressure ratio associated with the compressor component, (ii) direct the fuel control component to adjust the fuel flow to a value associated with the reduced compressor pressure ratio, and (iii) dynamically direct the at least one motor to provide an increased rotational force to the shaft in response to the reduced compressor pressure ratio induced by the gas discharge component after ignition of the fuel flow.
