SOLIS ALEMAN, Ernesto Miguel; RODRIGUEZ OLIVERA, Juan Luis  e  ALEMAN GARCIA, Mercedes. Modeling energetic and operational of the boiler feed water system of a power plant. Energética [online]. 2015, vol.36, n.3, pp. 303-312. ISSN 1815-5901.

Is proposed a combined model based on the parallel implementation of two functional approximators, using a neural network of the type (MLP) and a statistical regression to obtain the actual energetic and operation characteristics of the Boiler Feed Water System (BFWS) in a Power Plant, in which the water flow to the boiler is controlled by variation speed. The response of the combined model is obtained from the weighted sum of each functional approximator. This model is used to relate the current consumption and the position of the speed variator, in function of the discharge pressure and flow delivered by each pump of the BFWS. For the fit of the models is used save measurements of the historical file of the SCADA system, where is applied a data processing method to eliminating noise that can affect the fit of the models proposed.

Palavras-chave : operational characteristics of the system of pumping; artificial intelligence; boiler feed water system.
