Small synchronous machine protection during voltage sags caused by MV grid faults

This paper analyses the impact of symmetrical and unsymmetrical voltage sags caused by distribution and transmission faults on the dynamic behaviour of small salient-pole synchronous machines connected to the MV grid, and proposes the modification of the protection settings to increase machine avail...

Results from many cases are discussed, especially the positive-sequence voltage influence on machine stability. The study concludes that machine availability during unsymmetrical sags can be increased by modifying the undervoltage and overcurrent protection settings (the former should be based on the positive-sequence voltage instead of line-to-line voltages used in current settings).Peer Reviewed20182018-03-0120182018-01-11journal articlehttp://purl.org/coar/resource_type/c_6501AMhttp://purl.org/coar/version/c_ab4af688f83e57aainfo:eu-repo/semantics/articleapplication/pdfhttps://hdl.handle.net/2117/112630https://dx.doi.org/10.1016/j.epsr.2017.11.002reponame:UPCommons.
