System and method for turbomachinery vane diagnostics
First Claim
1. An actuation system of turbomachinery, comprising:
- a first actuator configured to control pitch of vanes of the turbomachinery;
a first positioner configured to position the first actuator to control the pitch of the vanes;
a second actuator configured to control the pitch of the vanes of the turbomachinery;
a second positioner configured to position the second actuator to control the pitch; and
a controller system communicably coupled to the first and second positioners, wherein the controller system is configured to;
drive the first positioner in an operation mode based at least in part on a set point of the turbomachinery, wherein the operation mode comprises driving the first actuator to exert a first force;
set the second positioner in a diagnostic mode rather than the operation mode, wherein the diagnostic mode comprises backdriving the second actuator to exert a second force in an opposite direction of the first force;
obtain data from the first positioner and the second positioner, wherein the data indicates operating conditions of the turbomachinery; and
control the turbomachinery based at least in part on the operating conditions of the turbomachinery.

Abstract
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.

11. Tangible, non-transitory, and computer-readable medium storing instructions thereon, wherein the instructions, when executed, are configured to cause a processor to:
-
drive a first positioner of a first actuator of vanes of turbomachinery in an operation mode based at least in part on a set point of the turbomachinery; set a second positioner of a second actuator of the vanes in a diagnostic mode rather than the operation mode, wherein the diagnostic mode comprises backdriving the second actuator against the first actuator; obtain data from the first positioner and the second positioner, wherein the data indicates operating conditions of the turbomachinery; and control the turbomachinery based at least in part on the operating conditions of the turbomachinery. - View Dependent Claims (12, 13)
