Description
Synchronization
Contactor Timeout
sec 0 25.5 0.5
When synchronization is detected, both
contactors will stay closed during this
timer.
Max Frequency
Difference
Hz 0.1 2.0 0.5
This is the maximum difference between
mains and genset frequencies to close
both contactors.
Phase to Phase Voltage
Check
- 0 1 0
0: Phase to neutral voltage check
1: Phase to phase voltage check
Max Volt Difference VAC 0 20 5
This is the maximum difference between
the mains phase-L1 and the genset
phase-L1 voltages to close both
contactors. If voltage transformer is used,
this quantity is multiplied with voltage
transformer ratio.
Max Phase Difference deg. 0 20 10
This is the maximum phase angle
between the mains phase-L1 and the
genset phase-L1 voltages to close both
contactors.
Phase Angle Offset deg. -60 +60 0
This parameter is used to compensate
the phase angle introduced by voltage
transformers in case of MV
synchronization. This angle value is
added to the phase differential during
phase matching process.
Dwell Timeout Sec 0.01 0.50 0.10
The synchronization conditions must
remain satisfied during this timeout for the
controller to decide to close its contactor.
Phase Synchronization G
Gain
% 0 200 20
This parameter governs the phase
synchronization speed.
If this parameter is increased, the
synchronization will be faster but
unstable. If it is decreased, the
synchronization will be slower but more
stable. The best setting is the fastest
stable synchronization.
Frequency
Synchronization G Gain
% 0 200 20
This parameter governs the frequency
synchronization speed.
If this parameter is increased, the
synchronization will be faster but
unstable. If it is decreased, the
synchronization will be slower but more
stable. The best setting is the fastest
stable synchronization.
Voltage Synchronization
G Gain
% 0 200 30
This parameter governs the voltage
synchronization speed.
If this parameter is increased, the
synchronization will be faster but
unstable. If it is decreased, the
synchronization will be slower but more
stable. The best setting is the fastest
stable synchronization.
Soft Transfer Enable - 0 1 0
0: Soft Transfer disabled
1: Soft Transfer enabled .
Soft Transfer Timer sec 0 240 30
This is the time duration of the Soft
Transfer. At the end of this timer one of
the contactors will release to terminate
the parallel operation
