ADE7116/ADE7156/ADE7166/ADE7169/ADE7566/ADE7569
ACTIVE ENERGY CALCULATION
As stated in the Active Power Calculation section, power is
defined as the rate of energy flow. This relationship can be
expressed mathematically, as shown in Equation 13.
power signal in the waveform register is continuously added to
the internal active energy register.
The active energy accumulation depends on the setting of
POAM (Bit 1) and ABSAM (Bit 0) in the ACCMODE register
P =
dE
dt
(13)
(Address 0x0F). When both bits are cleared, the addition is
signed and, therefore, negative energy is subtracted from the
active energy contents. When both bits are set, the ADE7166/
where:
P is power.
E is energy.
Conversely, energy is given as the integral of power.
ADE7169/ADE7566/ADE7569 are set to be in the more
restrictive mode, the positive-only accumulation mode.
When POAM (Bit 1) in the ACCMODE register (Address 0x0F)
is set, only positive power contributes to the active energy
E = ∫ P ( t ) dt
(14)
accumulation. When ABSAM (Bit 0) in the ACCMODE
register (Address 0x0F) is set, the absolute active power is used
The ADE7116/ADE7156/ADE7166/ADE7169/ADE7566/
ADE7569 achieve the integration of the active power signal by
continuously accumulating the active power signal in an
internal, nonreadable, 49-bit energy register. The register
(WATTHR[23:0], Address 0x01) represents the upper 24 bits
of this internal register. This discrete time accumulation or
summation is equivalent to integration in continuous time.
Equation 15 expresses the relationship.
for the active energy accumulation (see the Watt-Absolute
Accumulation Mode section).
The output of the multiplier is divided by the value in the WDIV
register (Address 0x24). If the value in the WDIV register is
equal to 0, the internal active energy register is divided by 1.
WDIV is an 8-bit, unsigned register. After dividing by WDIV,
the active energy is accumulated in a 49-bit internal energy
accumulation register. The upper 24 bits of this register are
E = ∫ p ( t ) dt = lim ? ∑ p ( nT ) × T ?
? ∞ ?
t → 0 ? n = 1 ?
(15)
accessible through a read to the active energy register
(WATTHR[23:0], Address 0x01). A read to the RWATTHR
where:
n is the discrete time sample number.
T is the sample period.
The discrete time sample period (T) for the accumulation
register in the ADE7116/ADE7156/ADE7166/ADE7169/
ADE7566/ADE7569 is 1.22 μs (5/MCLK). In addition to
calculating the energy, this integration removes any sinusoidal
components that may be in the active power signal. Figure 66
shows this discrete time integration or accumulation. The active
register (Address 0x02) returns the contents of the WATTHR
register, and the upper 24 bits of the internal register are cleared.
As shown in Figure 66, the active power signal is accumulated
in an internal 49-bit signed register. The active power signal can
be read from the waveform register by setting the WAVMODE
register (Address 0x0D) and setting the WFSM bit (Bit 5) in the
Interrupt Enable 3 SFR (MIRQENH, Address 0xDB). Like the
current and voltage channels waveform sampling modes, the
waveform data is available at sample rates of 25.6 kSPS, 12.8 kSPS,
6.4 kSPS, and 3.2 kSPS.
