Multilayer perceptron and neural networks
Marius-Constantin Popescu,Valentina Emilia Balas,Liliana Perescu-Popescu,Nikos E. Mastorakis +3 more
TL;DR: The paper presents the possibility to control the induction driving using neural systems and the best known methods to accelerate learning are: the momentum method and applying a variable learning rate.
Journal Article
Electromagnetic and thermal model parameters of oil-filled transformers
Nikos E. Mastorakis,Cornelia Aida Bulucea,Marius-Constantin Popescu,Gheorghe Manolea,Liliana Perescu-Popescu +4 more
TL;DR: In this article, the authors compared different methodologies to estimate thermal parameters with data from standardised heat-run tests and found that the main parameters required for the thermal model can be obtained only from the knowledge of transformer rated power.
Model for predictive control of temperature in oil-filled transformers
Nikos E. Mastorakis,Cornelia Aida Bulucea,Gheorghe Manolea,Marius-Constantin Popescu,Liliana Perescu-Popescu +4 more
TL;DR: In this paper, the authors compared different methodologies to estimate thermal parameters with data from standardised heat-run tests and found that the main parameters required for the thermal model can be obtained only from the knowledge of transformer rated power.
Transformer model extension for variation of additional losses with frequency
Marius-Constantin Popescu,Gheorghe Manolea,Cornelia Aida Bulucea,Niculae Boteanu,Liliana Perescu-Popescu,Ioan Ovidiu Muntean +5 more
TL;DR: In this article, the authors study transformer additional losses due to the presence of non-sinusoidal loads and present existing models to represent these losses and propose an original model to represent them.
