摘要： A method to determine eccentricity of a rotor in a turbine including: collecting sensor data of rotor eccentricity for a plurality of startup operations; establishing a baseline eccentricity value using the sensor data corresponding to a selected startup operation; determining an eccentricity value using the filtered sensor data for each of a plurality of startup operations subsequent to the selected startup operation; determining a rotor eccentricity difference between the baseline eccentricity value and each of the eccentricity values for the plurality of startup operations subsequent to the selected startup operation, and reporting a rotor eccentricity condition based on the rotor eccentricity difference.
