Evaluating through mathematical modelling the power equipment busbars electrodynamic strength under sudden short-circuit conditions

MATEC Web of Conferences, 2018
The electrodynamic strength, as forces acting between the current-carrying electric circuits are exerted as long as the currents exist, and have the tendency of deformation and displacement of the circuits.

CALCULATION OF THREE-PHASE CIRCUIT WITH ARBITRARY NUMBER OF LOADS [PDF]

Problems of the Regional Energetics, 2014
An algorithm for calculating the normal and emergency modes of three-phase circuits with distributed loads is elaborated. We propose to divide the required unknown currents into two groups: load currents are considered as principal, and currents in the ...

Modelación en coordenadas de fase del transformador monofásico con derivación central en el secundario Modeling in phase-coordinates of the single-phase transformer with center tap in the secondary winding

Revista Científica de Ingeniería Energética, 2013
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.

Short-Circuit Current Calculation of Single-Phase to Ground Fault in Petal-Shaped Distribution Network

Processes
Petal-shaped distribution networks are receiving increasing attention due to their enhanced reliability. However, the integration of distributed generators (DGs) significantly alters the fault characteristics during single-phase to ground faults. Traditional short-circuit calculation methods become inadequate due to the unmodeled effects of negative ...
