[ 1 ] - An Improved Big Bang-Big Crunch Algorithm for Estimating Three-Phase Induction Motors Efficiency
Nowadays, the most generated electrical energy is consumed by three-phase induction motors. Thus, in order to carry out preventive measurements and maintenances and eventually employing high-efficiency motors, the efficiency evaluation of induction motors is vital. In this paper, a novel and efficient method based on Improved Big Bang-Big Crunch (I-BB-BC) Algorithm is presented for efficiency e...
[ 2 ] - Estimation of Moisture in Transformer Insulation Using Dielectric Frequency Response Analysis by Heuristic Algorithms
Transformers are one of the most valuable assets of power systems. Maintenance and condition assessment of transformers has become one of the concerns of researchers due to huge number of transformers has been approached to the end of their lifetimes. Transformer’s lifetime depends on the life of its insulation and the insulation’s life is strongly influenced by its moisture attraction as well....
[ 3 ] - مدلسازی حالت گذرای حرارتی در ترانسفورماتور چند سیمپیچه دوطبقه مبتنی بر روش تفاضلات محدود و شبکههای عصبی مصنوعی
Nowadays, multi-winding transformers are widely used in traction systems and steel manufacturer. Multi-winding transformer that is used in these systems has especial geometry (that is usually called as split-winding transformer) and encounters with serious magnetic and thermal difficulties. According to the special geometry of split-winding transformer, studding the transient thermal behavior ...
