This embodiment is based on the first two embodiments.
In 2 months in 2019, when a synchronous line loss inspection is carried out in a certain power supply place, the fact that the alternating-current voltage value of a metering device provided by a special transformer user (a large industrial user collects basic electricity charge according to the required quantity) is normal is found in a metering automation system, the alternating-current values of the A phase and the C phase are basically equal, but the phase C current is a negative value, and the phase C current is shown in a table 1.
TABLE 1 load AC sampling values
After the abnormality is found, checking the on-site high-voltage metering device of the user one by one, and finding that the sealing of the on-site high-voltage metering device is good through the checking, wherein the secondary wiring of the C-phase current transformer is reversely connected to the high-voltage metering electric energy meter at the wiring terminal box, the wiring principle of the on-site metering device is shown in figure 4, and meanwhile, the voltage at the tail Uab of the on-site high-voltage metering device is found to be 24 degrees ahead of the Ia current through the measuring and checking; the Ucb voltage leads the Ic' current to be 144 degrees, and a vector diagram is drawn according to field measurement data to find that the load property is capacitive load as shown in figure 5.
The metering system finds out that the metering wiring error time of the household is from 2 months and 1 days of the new high-voltage installation to 2 months and 27 days of the new high-voltage installation, the generated active electric quantity is 89330kW & h, and the generated reactive electric quantity is 177070kvar & h, which are shown in the table 2.
TABLE 2 metering system table code values
According to the actual measurement data of the user site, calculating the active power P' of the three-phase three-wire metering device during the wiring error:
in the formula: u shape ab ，U cb Is the secondary voltage between phases when the V-V connection is carried out; i is a Secondary current of the phase A current transformer is obtained; -I c The secondary polarity of the C-phase current transformer is reversely connected with current;
the included angle between phase voltage and phase current is formed; u is the interphase voltage when the three phases are balanced; and I is the phase current in three-phase balance.
Calculating the active power P when the wiring is correctly connected:
in the formula: i is c Secondary current of C-phase current transformer
Calculating an active power correction coefficient:
obtaining the active power correction coefficient K by the simultaneous equations of the formula (1) and the formula (2)
And calculating reactive power Q' during the wiring error period according to the actually measured data of the user on site:
substituting formula (4) into formula (2) to obtain active power P when correctly wiring:
by combining the analysis of the two methods for calculating the compensation electric quantity, when the active power in the error period is calculated according to the actual measurement data of the user on site
We can directly count back sigma active electric quantity to Q 'during the user error'
Then, calculating the active total electric quantity sigma P and the reactive total electric quantity sigma Q during the wiring error period:
∑P＝P forward direction +|P Reverse direction |＝89.33+0.02＝89.35 (7)
In the formula: p is Forward direction of rotation Generating forward active power for the duration of the wiring error; | P Reverse direction | is the absolute value of the reverse active power generated during the wiring error.
∑Q＝Q Forward direction of rotation +|Q Reverse direction |＝177.07+0.39＝177.46 (8)
In the formula: q Forward direction Generating forward reactive power for the duration of the wiring error; | Q Reverse direction | is the absolute value of the reverse reactive power generated during the wiring error.
The calculation result of the formula (7) is expressed as Q ', and the calculation result of the formula (8) is expressed as P', and then we can take the formulas (3) and (6) to calculate the active power correction coefficient K:
and actually calculating the total active power:
ΔW p ＝(K×P')×G＝3.44×89.33×1000 ＝307295.2kW·h
in the formula: g is the comprehensive multiplying power of the user metering points.
Power adjustment for compensation:
△& L ＝[(△W P ×(Y p +Y F +Y N +Y M ))×L T ]－Y L ＝[307295.2×(0.3754+0.1616+0.0072+23)×0.5％]-483736.778 ＝-447561.68
in the formula: l is T The actual electricity fee increase and decrease (%) coefficient of a single fault electricity fee month is measured for a client, and is calculated as +0.5% through table look-up, Y L The single electricity rate month has paid the power transfer rate.
As shown in table 3, the formula for calculating the supplementary electric charge of the customer is:
&＝Δ& L +Δ& P +Δ& J +Δ& M +Δ& N +Δ& O = (-447561.68 +81824.061+5013195+35223.144+1569.348+ 5519.964) =4818069.957076 (yuan)
