Function description
Out-of-step protection
Functionality
The out-of-step protection (OOSPPAM (78)) function in the IED can be used for both
generator protection and as well for line protection applications.
The main purpose of the OOSPPAM (78) function is to detect, evaluate, and take the
required action during pole slipping occurrences in the power system.
The OOSPPAM (78) function detects pole slip conditions and trips the generator as fast
as possible, after the first pole-slip if the center of oscillation is found to be in zone 1,
which normally includes the generator and its step-up power transformer. If the center
of oscillation is found to be further out in the power system, in zone 2, more than one
pole-slip is usually allowed before the generator-transformer unit is disconnected. A
parameter setting is available to take into account the circuit breaker opening time. If
