Description
Parameter
No.
P/Pn
Cosφ
Phase
The active power as a percentage of P
N.
The displacement factor that is cosine of the
phase angle between the fundamental
components of the line to neutral point voltage
and the respective current.
Choose the over-excited or under-excited.
Activating
voltage
The lock-in voltage value that enables the
automatic reactive power delivery mode.
Activation threshold as a percentage of Un
corresponds to ‘lock-in’ voltage.
Deactivating
voltage
The lock-out voltage value that disables the
automatic reactive power delivery mode.
Deactivation threshold as a percentage of Un
corresponds to ‘lock-out’ voltage.
Some grid companies maybe requires two voltage thresholds as a percentage of Un to
activate or deactivate the function. The voltage thresholds normally call ‘lock-in’ and
‘lock-out’ voltage.
