DE LA TORRESILVA, Francisco; PALOMINO MARIN, Evelio; RODRIGUEZ-SOTO, Ángel Alexander  e  VARELA CANCINO, Jorge. 100 MW's evaluation of the mechanical dynamic functional behavior in steam turbines. Ingeniería Mecánica [online]. 2022, vol.25, n.2, pp. 49-55.  Epub 09-Set-2022. ISSN 1815-5944.

This work aimed at 100 MW's evaluation of the mechanical dynamic functional behavior in steam turbines of potency of electric generation, as from a model of multivariable statistical control of process ( Multivariable Statistical Control of Process - MSCP), that T2 of Hotelling uses the statistician 's like parameter symptom for the detection of the normal condition of the functioning of these turbines and the graphic of statistical control of process guy shewhart, for the statistician's monitoring T2 of Hotelling 's. A group model of parameters symptoms created of the turbine itself and the boss took like reference a sample of data representative of the population of gathered data, the standard normal condition of variability of the process represents which that they characterize this behavior. Methods were used as the mathematical and statistical modelation as from a model of statistical control of multivariable process. This model went validated as from a sample of data boss representative of the standard normal condition of variability of the process.

Palavras-chave : multivariable statistical control of process (MSCP); statistical Hotelling's T2; steam turbines; condition of the turbine; monitored on line; parameter symptoms.
