SYSTEM AND METHOD FOR DETERMINATION OF DISPLACEMENT OF BASIC VALUE OF ROTOR ECCENTRICITY

摘要

FIELD: power industry.;SUBSTANCE: method for determining the turbine rotor eccentricity involves collection of data on rotor eccentricity from sensors for multiple start-up operations; setting of basic eccentricity value using the data from the sensors, which correspond to the chosen start-up operation; determination of eccentricity value using the filtered data from sensors for each of multiple start-up operations following the chosen start-up operation; determination of rotor eccentricity difference between basic eccentricity value and each of the eccentricity values for multiple start-up operations following the chosen start-up operation; and submission of information on the state of rotor eccentricity based on difference of rotor eccentricity.;EFFECT: invention allows improving the availability and reliability of rotor eccentricity data, and reducing the costs for maintenance and operation of steam turbines.;10 cl, 4 dwg
