Only one of the four VAr functions (
Volt/VAr
,
Watt/VAr
,
Constant PF
,
Constant VAr
) can be enabled at one time.
12
PF export
and
PF import
must both be either enabled or disabled. It is not valid to have one enabled while the other is disabled.
This is the
Constant PF
function from IEEE 1547-2018 and the previous notes.
13
By default,
PF export
is set to under-excited while
PF import
is set to over-excited. Modification of those defaults is only possible
through SunSpec or 2030.5 communications.
14
Power Factor during export should always be absorbing, and during import it should be injecting. This will be made clear in a pending
update to IEEE P1547.9. The simple reason is that during active power export voltage will tend to rise and absorbing VArs will help pull
voltage back down. Conversely, during active power import, voltage will tend to drop and injecting VArs will help to pull voltage back up.
This minimizes the impact on voltage from changes in active power import and export.
