[Default]
2 100 to 150 % The maximum permissible positive deviation of the generator voltage from the
generator rated voltage (parameter
[110 %]
This value may be used as a voltage limit switch. The conditional state of this
switch may be used as a command variable for the LogicsManager (02.03).
2 50 to 100 % The maximum permissible negative deviation of the generator voltage from
the generator rated voltage (parameter
[90 %]
This value may be used as a voltage limit switch. The conditional state of this
switch may be used as a command variable for the LogicsManager (02.03).
2 100.0 to 150.0 The maximum permissible positive deviation of the generator frequency from
% the rated system frequency (parameter
[105.0 %] This value may be used as a frequency limit switch. The conditional state of
this switch may be used as a command variable for the LogicsManager
(02.04).
2 50.0 to 100.0 % The maximum permissible negative deviation of the generator frequency from
the rated system frequency (parameter
[95.0 %]
This value may be used as a frequency limit switch. The conditional state of
this switch may be used as a command variable for the LogicsManager
(02.04).
This controller provides the user with two alarm levels for generator
overfrequency. Both alarms are definite time alarms.
Monitoring for overfrequency faults is performed in two steps.
Refer to
for the triggering characteristic of this monitoring function. The dia‐
grams listed there show a frequency trend and the associated
pickup times and length of the alarms.

If this protective function is triggered, the display indi‐
cates "Gen. overfrequency 1" or "Gen. overfrequency
2" and the logical command variable "06.01" or
"06.02" will be enabled.

The parameter limits listed below have identical setting
ranges. Each parameter may be configured with dif‐
ferent settings to create unique trip characteristics for
specific thresholds.
