Existe un modelo en la literatura para representar el transformador monofásico con derivación central en el secundario. No obstante, dicho modelo representa toda la impedancia del transformador en el secundario, lo que difiere de la realidad. La distribuc... see more

El uso de dispositivos basados en electrónica de potencia, los cuales son fuentes de distorsión armónica, conducen a las redes eléctricas a convertirse en receptores de estas tensiones y/o corrientes no-sinusoidales. Entre los equiposque han sufrido un im... see more

The device is intended for compensating the reactive capacity of circuit with simultaneous stabilization of the loading voltage. It includes a high-frequency single-phase transformer which is included between two converters. One of the converters is fitte... see more

This paper proposes an algorithm for fault detection, faulted phase and winding identification of a three-winding power transformer based on the induced voltages in the electrical power system. The ratio of the induced voltages of the primary-secondary, p... see more

Introduction: Given the importance of the country's electricity industry for influencing most of the productive processes of the economy, the challenges in the changes in the energy market and the new regulations for producers, it is necessary, from the a... see more

This study deals with an effort to reduce inrush current of single phase transformer during its energizing. Inrush current affected by residual flux was minimized using demagnetization method in order to reduce residual flux trapped in the core of transfo... see more

Multiphase (more than three) power system has gained popularity due to their inherent advantages when compared to three-phase counterpart. Multiphase power supply is extensively used in AC/DC multi-pulse converters, especially supply with multiple of thre... see more

Real world problems such as scientific, engineering, industrial problems are in the form of the multi-objective optimization problems. In order to achieve optimum solutions of such problems, multi-objective optimization algorithms are utilized. In this st... see more

El análisis de redes eléctricas ha transitado de modelos en componentes de secuencia a modelos en coordenadas de fase. La formulación del barrido de frecuencia en coordenadas de fase, además de facilitar la modelación más precisa de las redes desequilibra... see more
