Synchronous generators of any size require protection against loss of excitation because it
can cause harmful effects to the generator and power grid. This paper proposes a new …

The excitation system of a synchronous generator has a major role in proper operation and
control of the generator. Loss of excitation (LOE) may cause harmful effects on the both …

This study introduces a new analytical approach for the detection of loss of excitation (LOE)
in a synchronous generator that uses only one local variable. The proposed method applies …

This paper 1) introduces a new approach for dependable and secure detection of loss-of-
field (LOF) events based on estimating rotor signals, 2) implements digital algorithm of the …

Loss-of-field (LOF) phenomenon in synchronous generators may cause equipment damage
and voltage drop in the power system, which can be terminated to a blackout. Conventional …

Loss‐of‐excitation (LOE) relays work under pre‐defined operating characteristics. If an
abnormal condition should arise, such operating characteristics might not be suitable for …

Loss of excitation (LOE) event threatens both the generator and power system stability.
Numerous approaches have been proposed for LOE detection, most of which use the …

This paper outlines a novel loss of excitation (LOE) protection scheme for synchronous
generators (SGs) based on reactive power increment (RPI) strategy and tracking the …

In this article, we present a new approach to the detection of Loss-Of-Excitation (LOE), a
typical failure of synchronous generators. Unlike most of the algorithms proposed in the …

Loss of Excitation (LOE) is an important fault in synchronous generators which may cause
the generator outage due to out-of-step (OS) conditions. Since the LOE protective relays act …
