Lower obtained every other embodiment, shall fall within the protection scope of the present invention.
Currently, during the electricity charge in ammeter wiring error are remedied, using the electricity of the history same period or upper some months as
Foundation is remedied, but the accuracy rate that electricity consumption data obtained from current electricity consumption should be calculated based on history electricity consumption is relatively low, base
In this, a kind of electricity consumption computational methods, device and electronic equipment provided in an embodiment of the present invention can solve in the prior art
Electricity consumption data accuracy is relatively low obtained from calculating current electricity consumption based on history electricity consumption when existing ammeter wiring error
The technical issues of.
For ease of understanding the present embodiment, first to a kind of electricity consumption calculating side disclosed in the embodiment of the present invention
Method, device and electronic equipment describe in detail.
Embodiment one：
A kind of electricity consumption computational methods provided in an embodiment of the present invention, as three-phase and four-line under CT ammeter false wirings
Practical electricity consumption restores computational methods, as shown in Figure 1, this method includes：
S11：Obtain the three-phase data of wiring error ammeter record.
Specifically, using DLT645-2007 stipulations multifunctional electric energy meter every 15 minutes record client's three-phase real-time voltages,
The function of the numerical value such as electric current, active power, reactive power, power factor (PF) obtains the three-phase data of wiring error ammeter record.
S12：Judge power load attribute according to three-phase data.
As a preferred embodiment, according to the three-phase data recorded, judge that customer charge belongs to perception or capacitive.
S13：It is based on power load attribute according to three-phase data, judges the Wrong wiring way of ammeter.
In practical applications, data are recorded according to the related ammeter after false wiring, judges connecing under ammeter false wiring
Line mode.
S14：According to Wrong wiring way obtain wiring it is correct in the case of average electric power.
As the preferred embodiment of the present embodiment, every 15 minutes mean powers are restored according to Wrong wiring way.
S15：Several electric powers that are averaged are calculated, total electricity consumption is obtained.
It in this step, is calculated, is restored practical total in the wiring error time according to several electric powers that are averaged
Electric power and electricity consumption provide effective data reference to be remedied for the electricity charge, facilitate related personnel to formulate the electricity charge and remedy scheme,
And client is made to be easier to connect love and remedy plan content.
It is existing during metering device operation and maintenance, feelings of the three-phase and four-line with CT ammeter wrong lines can be encountered often
A large amount of clients are carried out replacement metering device by condition, and increasing due to the transformation of low pressure electric meters collecting in the short time, metering dress occur
The case where setting wiring error increased.Therefore need the electricity charge after wiring error are remedied, at present with the history same period or on
The electricity of some months is used as and remedies foundation, but user is relatively low to the recognition rate for the scheme of remedying, and the electricity charge is caused to remedy work difficulty
It is larger.For the prior art, current electricity consumption is remedied using history electricity consumption, that is, is based on history electricity and calculates now
Electricity consumption lacks accurately and effectively real time data support, keeps client's receptance generally relatively low, seriously affect customer satisfaction, lead
It is more difficult that the expense of sending a telegraph remedies work.
In the present embodiment, electricity charge reduction is carried out according to the practical electricity consumption data of ammeter record and is calculated, to be provided in real time
Data support solve the problems, such as to calculate the electricity consumption in ammeter wiring wrong time by history electrographic recording, solve client
The electric quantity compensating problem of different times different load rate makes to remedy electricity and is more nearly practical electricity consumption, and client is easier to receive
Plan content is remedied, working efficiency is remedied to promote the electricity charge, reduces the discontented situation of client, therefore is solved in the prior art
Electricity consumption number obtained from current electricity consumption is calculated based on history electricity consumption when existing three-phase and four-line band CT ammeter wiring errors
According to the relatively low technical problem of accuracy rate.

Pressure-wire is with current line across being connected, and ammeter cannot can measure electricity, but the DLT-2007 used now completely under three-phase equilibrium
Stipulations ammeter, can every 15 minutes record apply ammeter on voltage value, current value, power factor (PF) value, active power and
The related datas such as reactive power.After ammeter two-phase voltage line and across the phase wrong of current line, ammeter remains to correctly record each phase electricity
Pressure value, current value, but power factor angle can become：One phase isAnother phase is
S22：Judge power load attribute according to three-phase data.
Preferably, according to the three-phase data recorded, judge that customer charge belongs to perception or capacitive.Therefore, power load
Attribute is inductive load or capacitive load.
S23：When power load attribute is inductive load, cosine function curvilinear characteristic is utilized according to three-phase data, is judged
Advanced across the phase connection phase and across the phase connection phase of lag of ammeter.
It should be noted that data are recorded using derived ammeter, it is special according to cosine function curve under inductive load
Sign, i.e., phase angle isPower factor absolute value be centainly less thanPower factor absolute value, thus, it is possible to judge
Wiring is in advance across that phase of phase connection, and wiring is that phase of lag across phase connection.
S24：Correct three phase power factor value is determined according to Wrong wiring way.
Further, meter voltage phase sequence, electricity under false wiring can be uniquely determined according to the mode of connection of the mistake
Flow phase sequence and each mutually correct power factor (PF) value.
S25：It is calculated, is connect according to three-phase voltage value, three-phase electricity flow valuve and correct three phase power factor value
Average electric power in preset time period in the case of line is correct.
As a preferred embodiment, according to every phase voltage value, the power factor (PF) value per phase current values and in the case of correct,
Each practical electric power can be calculated as average electric power in this 15 minutes.
S26：Accumulation calculating is carried out to the average electric power in each preset time period, obtains ammeter wiring wrong time
Interior total correct electricity consumption.
In this step, the average electric power data in each 15 minutes are pressed to above step S21 respectively to step S25's
Method is calculated, and result of calculation is added up, you can obtains the correct electricity consumption reducing value under ammeter false wiring.
As the another embodiment of the present embodiment, the range of false wiring refer to the accession to the out of phase pressure-wire of ammeter,
Current line is across that can cause ammeter to measure serious misalignment or even cannot measure under phase connection, this wiring condition, to need to carry out electricity
Amount reduction calculates.If scene is same phase current or electric voltage reverse-connection, phase ammeter metering reversion, because of current DLT-2007 stipulations
Ammeter can record reversed electricity, therefore be not necessarily to carry out electricity reduction calculating in the case, only need to read contiguous items in ammeter
Data.
