Turbine rotors are influenced by plenty of various circumstances while operated. One of them is a heterogenous temperature field that appears for example within through heating of a turbine and its particular parts in terms of commissioning. This kind of circumstance causes temporary deformation – inflexion of a rotor, which is professionally denoted as eccentricity. If eventual rotor eccentricity is not detected in advance then a turbine can be damaged or crashed in the extreme while getting over critical speeds of a rotor in terms of starting-up. The reason is that amplitudes of rotor vibrations are much higher in the area of the speeds because of resonance amplification as well as a large excitation force that is exactly caused by the eccentricity. Consequently, it is necessary to guarantee that a rotor is sufficiently aligned before starting-up. This can be accomplished for example by a time period of through heating to be properly set up. On the other hand, operational costs get increased when the period is too long.
