| contents | A virtual sensor for monitoring excited thermal turbogenerator rotors J. R. Gómez J. P. Monteagudo Ingeniería temperature Virtual sensor turbogenerator The working temperature of an electric generator’s parts is important for its proper operation. The turbogenerator rotor’s temperature is of particular interest regarding its protection and maintenance. Because of the difficulty of measuring the temperature of dynamic parts with real and implicitly robust artificial neural network (ANN) sensors it was decided to use a virtual sensor (VS) by which aver-age rotor winding temperature is estimated. Because ANN are characterised by learning through training rather than formal descrip-tions, this has made them the preferred choice for modelling processes involving complex interrelated variables; some are found in the field of instrumentation, as in this research. This paper presents the development of an ANN-based VS applied to an electricity generating company’s 4 MW turbogenerator. 2012 artículo científico 0120-5609 https://www.redalyc.org/articulo.oa?id=64324939002 en http://www.redalyc.org/revista.oa?id=643 Ingeniería e Investigación application/pdf Universidad Nacional de Colombia Ingeniería e Investigación (Colombia) Num.3 Vol.32 |
