In our case we can configure the values:
- Leading PF limit (min):
0.5
- Lagging PF limit 1 (max):
0.75
- Lagging PF limit 2 (max):
0.70
- Leading kVAr limit (%):
-60% (we can
read « -0.6 » on kVAr/kVA of the diagram
PQ)
- Lagging kVAr limit 1 (%):
for power factor
0.75 : nearly « 0.62 »,either 62%
- Lagging kVAr limit 2 (%):
for power factor
0.70 : nearly « 0.65 », either 65%
- Over voltage level:
110%
-
Delay:
10s
3.4.4.3 - Under-excitation Limitation
- This limitation is more sensible.
-
Iexc run limitation (A):
it corresponds to
the minimum value from which the limitation
will enter in action.
-
Iexc reset limitation (A):
value from which
the limitation is not active anymore.
- Under-excitation delay (s):
it must be
very short such as 2s.
3.4.4.4 - Over-excitation Limitation
-
Iexc run limitation (A):
this corresponds
to the highest value of the field current when
ceiling in short-circuit.
-
Iexc reset limitation (A):
this corresponds
the lowest value of the field current when
ceiling in short-circuit.
-
Iexc shutdown (A):
is the shutdown
current.
-
Iexc short-circuit (A):
excitation current
value to reach the short-circuit.
-
Short-circuit delay (s):
adjusted à 10s.

The customised part of the configuration is done and the remaining settings are the same as
described in the sections above.
3.5 - Advanced Grid code function
The D510C provides new features such as generator internal angle calculation, data log, LVRT
monitoring and recording. For more information please refer to the dedicated manual ref 5507.
