Description
Summary:The main objective of this work is to design a single-phase distribution transformer core type involved, with the help of optimization techniques to minimize total losses (core and windings). The optimization algorithms used are the differential evolution and particle swarm. His performances and results are compared. Moreover, it is detailed the importance of a good estimate of inrush current in transformers projects, its interference in security systems and electric power system in general. The main parameters of the project, the core dimensions, total losses, the no-load current and the transient magnetization current are computed through Octave software. These values are used to determine the geometry of the active part of the transformer in order to simulate the magnitude of flux density in the transformer core and the losses through finite element method using FEMM (Finite Element Method Magnetics) software. It was through the results the effectiveness of the methodology used, with reducing losses, improving the efficiency and significant decrease of the Inrush current.
