A new air gap flux‐based technique to detect loss of field in synchronous generators

open access: yesIET Electric Power Applications, Volume 18, Issue 5, Page 543-555, May 2024.
A new technique is proposed for loss of field (LOF) detection in synchronous generators (SGs). The proposed scheme employs the variations of SG angular velocity and load angle to reach this goal, while the mentioned parameters are estimated through air gap flux estimation.
