20.500.12556/DKUM-66215 Simulations of transformer inrush current by using BDF-based numerical methods This paper describes three different ways of transformer modeling for inrush current simulations. The developed transformer models are not dependent on an integration step, thus they can be incorporated in a state-space form of stiff differential equation systems. The eigenvalue propagations during simulation time cause very stiff equation systems. The state-space equation systems are solved by using A- and L-stable numerical differentiation formulas (NDF2) method. This method suppresses spurious numerical oscillations in the transient simulations. The comparisons between measured and simulated inrush and steady-state transformer currents are done for all three of the proposed models. The realized nonlinear inductor, nonlinear resistor, and hysteresis model can be incorporated in the EMTP-type programs by using a combination of existing trapezoidal and proposed NDF2 methods. simulations transformers numerical methods simulacije transformatorji numerične metode true false true Angleški jezik Slovenski jezik Znanstveno delo 2017-06-15 08:57:13 2017-06-15 08:58:06 2022-07-10 03:06:56 2021-05-15 03:35:37 0 0 0 str. 1-10 Letn. 2013 2013 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1024-123X 004.8 12769113 17118486 10.1155/2013/215647 1024-123X URN:SI:UM:DK:EIAPH1JI Mathematical_Problems_in_Engineering_2013_Tokic,_Uglesic,_Stumberger_Simulations_of_Transformer_Inrush_Current_by_Using_BDF-Based_Numeri.pdf Mathematical_Problems_in_Engineering_2013_Tokic,_Uglesic,_Stumberger_Simulations_of_Transformer_Inrush_Current_by_Using_BDF-Based_Numeri.pdf 1 CCC32B606FB20403C56408B4F5831661 1deed712f86bcadbe15510a1a0140d67f794ee924e23984d05653ce13ee7ab3f 3f6db96d-7c0e-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=112575 http://www.hindawi.com/journals/mpe/2013/215647/ 1 https://dk.um.si/Dokument.php?lang=slv&id=112574 Fakulteta za elektrotehniko, računalništvo in informatiko 0 0 0
