9.2.5 Power flow monitoring
A reversal of power flow occurs if the active power is negative. You can set
the following parameters for this:
▪ Hysteresis
▪ Delay time
▪ Behavior
1. Go to
Settings > Parameters > Grid > Power flow monitoring
.
2. Select the desired parameter.
3. Set the desired parameter.
4. Press the
Accept
button to save the modified parameter.
Hysteresis
You can use this parameter to set the hysteresis. You can use this to avoid
the unnecessary generation of messages if the measured value fluctuates
around a threshold value.
Delay time
You can use this parameter to set the delay time in order to delay the issuing
of the event message.
Behavior for reversal of power flow
You can use this parameter to set the behavior in the event of a reversal of
power flow. You can select the following options:
Setting
Behavior
Off
▪ The negative power flow is ignored.
▪ Automatic regulation remains active.
Event only
▪ The
Reversal of power flow
event is issued.
▪ If Z compensation is activated, this function is deacti-
vated.
▪ Automatic regulation remains active.
Auto blocking
▪ The
Reversal of power flow
event is issued.
▪ If Z compensation is activated, this function is deacti-
vated.
▪ Automatic regulation is blocked.
