High-speed directional protection without voltage sensors for distribution feeders with distributed generation integration based on the correlation of signals and machine learning
(Elsevier Science SA, 2020-03)
This paper proposes a novel methodology to define fault current direction along the Distribution Feeder (DF) considering Distributed Generation (DG) integration. The proposed methodology is based on Empirical Decomposition ...
Combined control of a distribution static synchronous compensator/flywheel energy storage system for wind energy applications
(Institution of Engineering and Technology, 2012-06)
The integration of wind power generation in power systems is steadily increasing around the world. This incorporation can bring problems onto the dynamics of power systems owing to the lack of controllability over the wind ...
Wind power converters improving the power system stability
(Institution of Engineering and Technology, 2016-05-05)
This study analyses the coordinated actions of modern wind power plants for improving the transient and small-signal stability in power systems. Supplementary controls on wind farms are considered, and specific modifications ...
Dissolved gas analysis differences between natural esters and mineral oils used in power transformers: a review
(Institution of Engineering and Technology, 2019-09)
Typically and historically mineral oil has been used as liquid insulation in power transformers. Its functions are to ensure the isolation between active parts, absorb heat transmitting it to the outer surfaces, and protect ...
Power transformers monitoring based on electrical measurements: State of the art
(Institution of Engineering and Technology, 2018-07-10)
Faults diagnosis in power transformers has been traditionally based on the insulation resistance measurement, polarisation index, analysis of dissolved gasses in oil, dissipation/power factor measurement, and partial ...
Índice para la localización de fallas basado en caídas de tensión en sistemas de distribución de energía eléctricaFault location index for distribution power system restoration using voltage sags
(Asociación Argentina Mecánica Computacional, 2018-11)
Debido a la expansión de los sistemas de distribución de energía, garantizar un servicio sininterrupciones es un área de gran interés en el estudio de los sistemas eléctricos. En este contexto, lossistemas de distribución ...
