Abstract :
Significant changes have occurred in the protection of generators in the past ten years as discussed in IEEE guide C-37.102. This paper discusses these changes as well as the risks of not addressing them. It specifically addresses the risks in two functional areas where 20+-year-old generator protection is inadequate. These areas include: sensitive stator ground fault protection using schemes to provide 100% winding ground detection, field ground fault protection, and inadvertent (accidental) generator off-line energizing protection. Most of these upgrade schemes were made possible through the use of digital protection
