Abstract
Systems and methods include actuation system of turbomachinery that include an actuator configured to control pitch of vanes of the turbomachinery and a positioner configured to position the actuator to control the pitch. The actuation system also includes a controller system communicably coupled to the positioner. The controller system is configured to drive the positioner based at least in part on a set point of the turbomachinery and obtain data from the positioner indicating an amount of force used for a target pitch. Using the data, the controlling system derives an operating condition for the turbomachinery and controls the turbomachinery based at least in part on the operating condition of the turbomachinery.
Claims15
An actuation system of a turbomachine having vanes, comprising:
- one or more positioners, one or more actuators, or one or more motors for setting a pitch of the vanes;
- a controller system communicably coupled to the one or more positioners, the one or more actuators, or the one or more motors, wherein the controller system is configured to:
- obtain data from the one or more positioners, the one or more actuators, or the one or more motors indicating an amount of force used to set the pitch of the vanes;
- using the data, derive an operating condition for the turbomachine;
- based on the operating condition, derive a target pitch for the vanes;
- drive the one or more positioners, the one or more actuators, or the one or more motors to set the vanes to the target pitch.
A tangible, non-transitory, and computer-readable medium storing instructions thereon, wherein the instructions, when executed, are configured to cause a processor to:
- obtain data from one or more positioners, one or more actuators, or one or more motors indicating an amount of force used to set a pitch of vanes of a compressor of a turbine system;
- using the data, derive an operating condition for the compressor;
- based on the operating condition, derive a target pitch for the vanes;
- drive the one or more positioners, the one or more actuators, or the one or more motors to set the vanes to the target pitch.
