Abstract

AGUDELO, Laura; VELILLA, Esteban  and  LOPEZ, Jesús M. LOAD ESTIMATION OF POWER TRANSFORMERS USING AN ARTIFICIAL NEURAL NETWORK. Inf. tecnol. [online]. 2014, vol.25, n.2, pp.15-23. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642014000200003.

This paper presents a methodology for load estimation of power transformers by means of arfificial neural networks. To implement the proposed methodology the data of two power transformers, located in different geographical areas and wifh different operational conditions, were considered. The load estimation methodology was implemented using historical data provided by the company Interconexión Eléctrica S.A. (ISA). To predict the load curves a neural network was trained using MATLAB, being able to fit a load curve with daily and weekly prediction times. The proposed method allows the estimation of load curve values in power transformers with an average percent relative error of around 10%. The method described in this paper can be applied fo other equipment with similar operating characteristics.

Keywords : electric load curve; power transformers; artificial neural networks.
