24
S
acinv-
Photovoltaic inverter Apparent Power AC negative
P
lt
Phase long term flicker (2 hours), including P
ltpg
(phase p to phase g
long term voltage flicker) and P
ltp
(phase p to neutral long-term
voltage flicker). See 5.1.10 for definition.
P
st
Short term flicker (10 minutes) including P
stpg
(phase p to phase g
short term voltage flicker) and P
stp
(phase p to neutral voltage
flicker). See 5.1.10 for definition.
P
st(1min)
Short term flicker (1 minute) including P
st(1min)pg
(phase p to phase g
short term voltage flicker) and P
st(1min)p
(phase p to neutral voltage
flicker). See 5.1.10 for definition.
P
inst
Instantaneous flicker including P
instpg
(phase p to phase g
instantaneous voltage flicker) and P
instp
(phase p to instantaneous
voltage flicker). See 5.1.10 for definition.
 N
Instantaneous combined (fundamental and nonfundamental)
nonactive phase power including  Np (phase p nonactive phase
power). Minus sign indicates generated and plus sign indicate
consumed nonactive power. See 5.1.5 for definition.
N
ind

N
cap

Recorded phase combined
(fundamental and nonfundamental)
nonactive power including N
cap/ind
p
(phase p nonactive phase power).
Suffix ind/cap represents
inductive/capacitive character. Minus
sign indicates generated and plus sign
indicates consumed fundamental
reactive power. This parameter is
recorded separately for each quadrant as shown on figure. See 5.1.5
for definition.
 N
tot
Instantaneous combined (fundamental and nonfundamental)
nonactive total vector power. Minus sign indicates generated and
plus sign indicate consumed nonactive power. See 5.1.5 for
definition.
N
totind

N
totcap

Recorded total vector combined
(fundamental and nonfundamental)
nonactive power. Suffix ind/cap
represents inductive/capacitive
character. Minus sign indicates
generated and plus sign indicates
consumed combined nonactive
power. This parameter is recorded
separately for each quadrant as
shown on figure. See 5.1.5 for definition.
 Na
tot
Instantaneous combined (fundamental and nonfundamental)
nonactive total arithmetic power. Minus sign indicates generated
and plus sign indicate consumed nonactive power. See 5.1.6 for
definition.
Na
totind

Recorded total arithmetic combined (fundamental and
nonfundamental) nonactive power. Minus sign indicates generated
