essentially impacts the tolerance range and the number identified
grid switches.
The parameter 'Exceed resonance peak' usually disabled,
meaning that the resonance point not exceeded unless has for tuning. The coil is
positioned the determined tuning point after the first estimate has been completed.Page 102 Detailed description REG-DP/ REG-DPA parameters
We take care it.
Note:
This setting makes sense the grid conditions are very unbalanced, meaning that there are
very high zero sequence voltages the resonance point.1.
0 Avoid resonance peak
The coil started the opposite direction and reversed necessary the system can
search the falling edge (away from the resonance point). This occurs frequently compen-
sated 110 overhead transmission grids.
0 Adaptation Uref:
Grid switches are always relatively fast and over within few minutes.
0 Check resonance curve:
If the regulator displays 'Tune' and this parameter set, tolerance threshold placed
around the determined resonance curve. the zero se-
quence voltage does not leave the tolerance field during the set time, the current zero
sequence voltage will adopted the new reference voltage the end this observa-
tion period.)
. This function does not help with fast zero sequence
voltage changes. The tolerance range only consists the
absolute value the zero sequence voltage.
After the first estimate has been determined the falling edge, the direction changed
and new, normal search started the direction the resonance curve.1.
NO The angle measurement supressed. contrast, changes
due weather and crosstalk from load current changes are usually very slow. The number
of searches can reduced when the tolerance for slow changes adjusted. The size the tolerance range does not change.3. the measured value leaves this tolerance range
(due switching), the search aborted and new search started.
Default setting: min inactive)
Note:
Values smaller than min are invalid. (often cable networks)
0 Une angle measurement
Parameters Description
YES angle measurement performed when the synchronization voltage con-
nected.
In this case, the 'Forced search delay' used delay time (see section 11
