Faculty Electrical Engineering, Mathematics and Computer Science Department Delft Institute of Applied Mathematics Date 2013-12-31 Abstract Due to increasing levels of fault currents, Fault Current Limiters (FCLs) are expected to play an important role in the protection of future power grids. Inductive saturable FCLs are particularly interesting due to their inherent reaction on the fault. Many different configurations have been proposed in literature. Being difficult or impossible to create accurate analytical models of some FCL configurations, the development of Finite Element (FE) models for inductive FCLs is required. This paper presents a 3D nonlinear transient FE modeling technique applied to two inductive FCLs, namely so-called open-core and three-leg single-core FCLs. The models have been validated by comparing simulation results with lab measurements. Results show excellent agreement. The models constitute a valuable tool for design, optimization and verification of inductive FCLs Subject fault current limitersfinite element modelingnonlinear magneticspower system protection To reference this document use: http://resolver.tudelft.nl/uuid:b3916b00-fb88-49fc-8f15-249597fd0423 Publisher Delft University of Technology, Faculty of Electrical Engineering, Mathematics and Computer Science, Delft Institute of Applied Mathematics ISSN 1389-6520 Source Reports of the Delft Institute of Applied Mathematics, 13-08 Part of collection Institutional Repository Document type report Rights (c)2013 The Authors Files PDF 13-08_Domenico_report.pdf 342.3 KB Close viewer /islandora/object/uuid:b3916b00-fb88-49fc-8f15-249597fd0423/datastream/OBJ/view
