S is a new measured value to be used for the protection function
S is the measured value given from the function in previous execution cycle

S is the new calculated value in the present execution cycle
Calculated
k is settable parameter by the end user which influence the filter properties
TD
Default value for parameter k is 0.00. With this value the new calculated value is
immediately given out without any filtering (that is without any additional delay).
When k is set to value bigger than 0, the filtering is enabled. A typical value for k=0.92
in case of slow operating functions.

Identification

Function description
Accidental energizing protection for
synchronous generator

Functionality

Inadvertent or accidental energizing of off-line generators has occurred often enough
due to operating errors, breaker head flashovers, control circuit malfunctions, or a
combination of these causes. Inadvertently energized generator operates as induction
