4.8 Power and Energy Results
The instantaneous voltage and current samples are
S 2 – P Active
Q WB =
P Active
multiplied to obtain the instantaneous power ( P1 , P2 )
(see Figure 3 and 4 ). The product is then averaged over
N conversions to compute active power ( P1 AVG ,
P2 AVG ).
Apparent power ( S1 , S2 ) is the product of RMS voltage
and current as shown:
S = V RMS ? I RMS
Power factor ( PF1 , PF2 ) is active power divided by ap-
parent power as shown below. The sign of the power
factor is determined by the active power.
PF = ------------------
S
Wideband reactive power ( Q1 WB , Q2 WB ) is calculated
by doing a vector subtraction of active power from ap-
parent power.
P1 AVG
2
Quadrature power ( Q1 , Q2 ) are sample rate results ob-
tained by multiplying instantaneous current ( I1 , I2 ) by in-
stantaneous quadrature voltage ( V1Q , V2Q ) which are
created by phase shifting instantaneous voltage ( V1 ,
V2 ) 90 degrees using first-order integrators. (See Fig-
related to line frequency, so their gain is corrected by
the Epsilon register, which is based on line frequency.
Reactive power ( Q1 Avg , Q2 AvG ) is generated by inte-
grating the instantaneous quadrature power over N
samples.
Active power ( P1 AVG , P2 AVG ), apparent power ( S1 , S2 ),
and reactive power ( Q1 AVG , Q2 AVG ) of the two channels
are summed up and then divided by 2. The calculation
results are placed in E PULSE , S PULSE , and Q PULSE reg-
isters which can be configured to drive energy pulse
outputs. (See Figure 6 .)
