Abstract

Distributed generation (DG) is increasingly employed in modern utility grids to address the growing complexity and size of consumer energy demands. The obstacles associated with DG integration are related to the additive effect the DG has on the short circuit current characteristics of power systems during short circuit conditions. This thesis proposes a novel mitigation technique for synchronous machine based DG integration effects on existing radial fuse-recloser protection infrastructure. The mitigation method provides a comparative analysis of the utilization of resistive (R), inductive (L) and resonant (LC) type superconducting fault current limiters (FCLs) for prevention of excessive fault current contribution from DG sources. Within the frame of reference of this thesis is an interrogation into the effects of synchronous machine based DG sources, in conjunction with mitigation capabilities of FCL integration in the context of fuse-recloser coordination, recloser sensitivity and recloser directionality behavior during radial distribution short circuit conditions. For validation purposes, the proposed methods are demonstrated on a suburban test benchmark using the PSCAD/EMTDC program.
