Throughout its transportation, from generation to final consumption, the electrical energy fluctuates its voltage levels. These variations are natural and provided by the system itself, but without effective corrections, ...

The economic load dispatch is one of the most important activities in the planning operation of an electric power system. Because, is the decision of power dispatch, took by the operator, that determines which transmission ...

As any other electric equipment, transformers have efficiency lower than 100%. The “lost” energy is dissipated as heat in the active part of the machine and later this heat must be transferred to the outside environment, ...

The following work presents an analysis on the impact and the financial performance of the Solar Photovoltaic Minigeration at the Federal University of Santa Maria, customer of group A4, considering the tariff and regulatory ...

This work presents an analysis of the current antenna system of NANOSATC-BR series satellites and the proposal of an alternative system using planar antennas. The NANOSATC-BR Program, Development of Cubesats aims to ...

This work presents a time domain study of the self-oscillating resonant converter, using state space representation to find the solutions of the initial conditions. After reviewing the literature, which aimed to evaluate ...

Considering that the switched power supplies are widely implemented as power supplies for the control and command circuits for the powering of electric engines, we sought to implement a switched power supply using the ...

The acquisition of data in the areas of generation, transmission and distribution is of extreme importance, since they form the basis of the Electric Power System. However, it presents the most complex and growing scope ...
