摘要： A gas turbine system includes a compressor. The compressor has a plurality of inlet guide vanes disposed at an inlet of the compressor. Furthermore, the compressor may have at least one unison ring coupled to a plurality of variable stator vanes disposed between the inlet and an outlet of the compressor. The gas turbine system includes a first actuator that may adjust a first pitch of the plurality of inlet guide vanes and a second actuator that may adjust a second pitch of the plurality of variable stator vanes. A first electric motor may drive the first actuator, while a second electric motor may drive the second actuator.

摘要： Systems and methods include an actuation system of turbomachinery includes a first actuator configured to control pitch of vanes of the turbomachinery and a first positioner configured to position the first actuator to control the pitch of the vanes. The actuation system also includes a second actuator configured to control the pitch of the vanes of the turbomachinery and a second positioner configured to position the second actuator to control the pitch. The actuation system also includes a controller system communicably coupled to the first and second positioners where the controller system is configured to drive the first positioner in an operation mode based at least in part on a set point. The controller system is also configured to set the second positioner in a diagnostic mode and obtain data from the first positioner and the second positioner where the data indicates operating conditions of the turbomachinery.

摘要： A method for initializing a generator may include sending a field reference voltage to an exciter that may provide a direct current (DC) current and a DC voltage to a rotor of a generator based on a current set point that corresponds to the field reference voltage. The method may then include receiving a voltage feedback signal output by the generator, determining one or more locations of one or more poles of the generator based on the voltage feedback signal, and sending one or more firing signals to one or more switches of a starter after determining the locations of the poles, such that the switches couple the voltage to a stator of the generator.
