SYSTEM AND METHOD FOR TURBOMACHINERY VANE PROGNOSTICS AND DIAGNOSTICS
First Claim
1. A system, comprising:
- an actuation system of a gas turbine system comprising an actuator, a positioner including one or more sensors, a motor, and a controller system communicably coupled to the positioner and the motor, wherein the actuator is coupled to one or more inlet guide vanes (IGVs) or variable stator vanes (VSVs) and configured to move the IGVs or VSVs, the positioner is configured to position the actuator so that the actuator moves the IGVs or VSVs to a desired angle, the motor is configured to drive the actuator, and the controller system is configured to;
establish one or more baselines for one or more types of data obtained by the sensors at initialization of the gas turbine system;
derive a deviation from the baselines; and
perform a preventative action if a deviation that meets or exceeds a threshold is derived.

Abstract
One embodiment includes a system including an actuation system of a gas turbine system including an actuator, a positioner including one or more sensors, a motor, and a controller communicably coupled to the positioner and the motor. The actuator is coupled to one or more inlet guide vanes (IGVs) or variable stator vanes (VSVs) and configured to move the IGVs or VSVs, the positioner is configured to position the actuator so that the actuator moves the IGVs or VSVs to a desired angle, the motor is configured to drive the actuator, and the controller is configured to establish one or more baselines for one or more types of data obtained by the sensors at initialization of the gas turbine system, derive a deviation from the baselines, and perform a preventative action if a deviation that meets or exceeds a threshold is derived.
