Distribution Transformer Losses Evaluation: A New Analytical Methodology and Artificial Neural Network Approach

The aim of this paper is to propose an analytical methodology and discuss some alternatives of artificial neural network models in order to evaluate losses in distribution systems, particularly in distribution transformers. The procedure can also be extended to other components of the distribution system (secondary and primary network and HV/MV transformers). This is accomplished by using the utility´s database such as the consumers´ monthly energy consumption and the typical load curves of each class of consumption and type of activity developed.
