Description
Technical field
The invention belongs to for electrical domain, more particularly, to a kind of check management and control system for user power utilization data centralized meter-reading system
System.
Background technology
From 2010, under the unified plan of State Grid Corporation of China, various places electric company starts to push forward low-voltage collecting meter reading comprehensively
Systematic difference, (is referred to as collected using the electricity consumption data that centralized automatic meter-reading management system (abbreviation centralized meter-reading system) carrys out concentrated collection user
Copy data), substantially realize all standing at present.Implement the purpose of this work, one is to reduce workload of checking meter, improve matter of checking meter
Amount, two are an up informationization and the automatization level of the management of power use.
From the point of view of practical situations, collection is copied data and disappearance, mutation or the problem inconsistent with meter show value often.
Copy data for improving collection for the accuracy entered an item of expenditure in the accounts, current way is：Before entering an item of expenditure in the accounts, collection is copied with shortage of data and abnormal (chain rate
Add drop width exceed certain limit) user implement artificial nucleus copy, copy data using core as foundation of entering an item of expenditure in the accounts；Two are, every 3～6 months
All users are carried out with artificial nucleus copy, core is copied and collection is copied the skew component enforcement electricity electricity charge and moved back/mend.In addition, portion
Point electric company also takes the lead in have developed collection copies defect elimination system, and the user monthly collection being copied shortage of data arranges out, carries out in time
Live defect elimination.Above-mentioned check defect elimination method and be ferreted out account accuracy rate and serve positive role to improving collection, but still send out in practice
Now following problem：
(1) collection copies data flaw phenomenon a lot, but current defect elimination is mainly searched collection and copied the user of shortage of data, to improve
Online rate and success rate, freeze the problems such as electricity bust, part day shortage of data and do not analyze and improve it is impossible to comprehensively to day
Find potential problem in centralized meter-reading system.
(2) the reason shortage of data or defect, is a lot of to cause collection to copy, and such as concentrator fault, electrical energy meter fault, carrier wave are believed
Number problem, platform area related question, multiplexing electric abnormality etc., find the premise that reason is solve problem accurately.Simply find out in working at present
Treat user's inventory of defect elimination, the reason cause shortage of data then completely will manually scene investigation, efficiency is low, is unfavorable for that defect elimination is appointed
That is engaged in completes in time.
(3) factors such as the whether abnormal incomplete size corresponding season transition with chain rate add drop width of data copied by collection
A moon power consumption can be led to significantly to change, cause normally to be mistaken for exception；Conversely, moon power consumption low level runs but less fluctuation
Stealing user but can be mistaken for normally.The former increased in vain and monthly manually mends the workload copied, and the latter then makes electricity again
The electricity charge are run off, are not given timely recovery.
(4) collection is copied with abnormal user and arranges after core copies, once finding that core is copied result and copied data with collection and has deviation, often just with
Core is copied data and is defined, and artificial nucleus is copied with quality and lacks necessary supervision and management and control.
(5) collection is copied data and is contained a large amount of useful informations, can instruct defect elimination, oppose electricity-stealing, that defect elimination/core copies quality evaluation etc. is many
The work of aspect, but be only used as at present entering an item of expenditure in the accounts according to one of；Meanwhile, defect elimination working group, inspection group, core are copied and are lacked between group again
Necessary information communication, is unfavorable for the timely discovery of problem and the advance to perfect order of work.
At present, collection copies the data following 5 kinds of situations of appearance for the moment, arranges artificial nucleus to copy：
(1) shortage of data：It is currently limited to current collection and copies can not find the positive total active energy of certain user in data and (freeze
Value) data, this is as the judgment basis treating defect elimination user；
(2) zero power：Referring to current positive total active energy (power consumption) is zero；
(3) total score mismatches：This refers to current positive total active energy (electricity consumption only for the user using tou power price
Amount) it is not equal to the situation of current point of rate active energy sum；
(4) enter an item of expenditure in the accounts first：Situation about entering an item of expenditure in the accounts for the first time after referring to apply to install a telephone；
(5) sequential growth rate >=50%：Refer to difference and the ratio of last power consumption of current power consumption and last power consumption
Absolute value is more than or equal to 50% situation.
The above-mentioned problem checking principle focuses primarily upon the exception in defect elimination principle and (2nd), (5) point in (1st) point
Decision principle, unreasonable is in particular in：
(1) defect elimination user object is defined in the situation that shortage of data copied by collection, and it is inwhole to there are in fact some data
Lack but the user of existing defects, data flaw includes part date data disappearance, freezes the phenomenons such as value mutation, if not to these
Phenomenon combing still cannot be judged to the correctness of accumulative electricity comprehensively.
(2) collection is copied the principle of moon power consumption " chain rate stability bandwidth 50% " in unusual determination and is not accounted for seasonal climate transition
Impact.Temperature sensitive users electricity consumption undulate quantity in season alternation is very big, can be mistaken for needing core to copy by this rule
User, increases core in vain and copies workload.
(3) moon power consumption " chain rate stability bandwidth 50% " check the impact that principle does not account for stealing factor yet.Stealing can
Reduced levels can be in using electricity, between the moon, have no too great fluctuation process, on the contrary may by this abnormal conditions of chain rate stability bandwidth principle
It is mistaken for normal, delay electricity charge recovery.
(4) check the impact that principle does not account for user's peculiar use power mode.Because Urbanus, floating population increase
Plus, quality of life raising, the many factors such as market economic development, Shanghai low-voltage customer (especially resident) emerge much
New model.For example, vacant room, rental housing, periodically spend a holiday/go on business/return to one's home village etc..If it is simple with power mode to depart from user itself
Single abnormal according to single month power consumption level and the judgement of chain rate stability bandwidth, will also result in erroneous judgement and increase in vain and check workload.
Above-mentioned series of problems substantially shows, raising collection is copied quality, lifting sales service level and collection and copied data analysis
The lifting close association of ability, complement each other.Its due effect is really played in application for enabling centralized meter-reading system, needs lifting badly
The analysis ability of data is copied to collection, and based on collection copy data analysis structure comprise defect elimination, check, check, entering an item of expenditure in the accounts, checking and rating etc. polycyclic
The operation flow of section, set up one kind more intelligent and comprehensive collect copy and check managing and control system, accurately to calculate whole electrical network
Yield, sales volume and loss, make power department can strengthen management according to its data, make an inventory stock, and reduce loss makes up burst.

(4) total score mismatches and judges (the 4. walk)：Of that month each rate active energy sum is not equal to this month always active electricity
The user of amount lists in and treats that core plagiarizes family inventory, and remaining user executes subsequent step.
(5) abnormal first sentence (the 5. walk)：Using current conventional decision rule, will current power consumption be zero or moon electricity consumption
It is judged to exception at the beginning of the user of amount chain rate stability bandwidth >=50%.Just sentence normal users and be classified as the user that can enter an item of expenditure in the accounts, be just judged to abnormal use
Family executes subsequent step.
(6) abnormal secondary judgement (the 6., 7. walk) copied by collection：Implement electricity consumption pattern-recognition to being just judged to abnormal user,
Obtain of that month total active energy zone of reasonableness on this basis, to such user whether exception and belong to and need inspection (stealing can
Doubt)/need the situation that core is copied to be differentiated.Thus finally sort out current wait to check, treat core copy, user's inventory of can entering an item of expenditure in the accounts.
In Fig. 4, technical scheme, a kind of two benches decision algorithm based on pattern-recognition is proposed.Use from low pressure
Remove in family confirmable treat defect elimination user after, to remaining users implement this two benches decision algorithm, you can combing goes out
When expectation core is copied, waited to check, can enter an item of expenditure in the accounts user's inventory.
Two benches decision method is sentenced at the beginning of including, two links of secondary judgement, below the algorithm of this two links is given carefully
Change.
First, just sentence method：
The preliminary judgement that data exception copied by collection preferably adopts relatively simple algorithm, because this interannular area is to large number of use
Family, it is therefore an objective to it may be the user of exception that preliminary screening goes out, reduces the scope of secondary judgement, improving the efficiency of secondary judgement.For
This, continue to use current abnormality determination method substantially, copies active total electricity level by of that month collection and electricity chain rate stability bandwidth is carried out
Just sentence.
But it is noted that when under remote meter reading environment pair mistake or user destroy point rate register and all can lead to a point expense
Rate active energy distortion, this data exception is more hidden, not necessarily affects the aggregate-value of total active energy, but due to peak, paddy
Period electricity there occurs deviation, still electricity charge income can be impacted.
For this reason, the technical program makes following improvement to method of just sentencing, that is,：Except investigating the chain rate of the total active power consumption of the moon
Outside stability bandwidth, also investigate the stability bandwidth of the active electricity consumption proportion of each rate (i.e. timesharing), if the chain rate fluctuation of any of which one
Rate >=50% is all just judged to exception.So, through secondary judge after, when meter exists pair, the user of mistake can be put into and treats core
Plagiarize family inventory, and the user destroying point rate register can be put into user's inventory to be checked.
Hereinafter remember that current is Y, the M month；Represent that the active total electricity consumption of the current forward direction of k-th user of gained copied by collection
Amount；Represent current for just sentence the moon active power consumption lower limit (copy depending on core and inspection group personnel configuring condition, can use
The value of zero or very little, this project is subsequently only investigated zero power user, is taken)；Work as k-th user
The chain rate stability bandwidth of gained active moon total electricity consumption copied by phase collection；Copy the gained paddy period for the current collection of k-th user active
The sequential growth rate of electricity consumption proportion.Under above-mentioned notation convention, collection is copied the first of data exception and is sentenced rule as shown in Table 1 below.
When just sentencing, first judge this user current whether be low (zero) power consumption；It is not that low (zero) electricity judges chain rate ripple again
Dynamic rate；When stability bandwidth judges, if user's electricity last month is zero, directly it is judged to that this user is current normal, only to electricity consumption last month
The user of amount non-zero calculates chain rate stability bandwidth.So on the one hand make algorithm feasible, on the other hand also force zero power problem to exist
Just give attention when occurring for the first time and verify.
The decision table sentenced at the beginning of data exception copied by table 1 collection
2nd, secondary decision method：
Implement secondary judgement to being just judged to doubtful abnormal user further.The target of secondary judgement is to discriminate between out treating core
Copy, wait to check, can enter an item of expenditure in the accounts user, overall procedure is as shown in Figure 4.
Wherein there is following basic principle：
(1) if user is closely having stealing record in two years, once current power consumption is zero or current power consumption
Decline to a great extentOr paddy electricity proportion is uprushedTend to be judged to treat that inspection is used
Family.
(2) if no steal electrographic user current power consumption is zero, need to carry out the differentiation of zero power power mode.
So-called zero power pattern, refer to this user power utilization amount be zero for a long time, small incidental expenses charge condition often occurs or the same period last year occur or
The situation of zero power.For zero power mode user, if check in half a year recorded for normal, still it is judged to normal；
If no check in half a year recording (including not carrying out checking or checking in half a year for abnormal two kinds of situations) for normal,
It is judged to treat that core plagiarizes family.
(3) to no history stealing record and have more than 2 years collection and copy the user of data, need unfolding model stability distinguishing,
With reference to the zone of reasonableness of the current power consumption of history electricity consumption model prediction, and then judge whether current power consumption is abnormal.
(4) for no history stealing record but collection copies full 2 years of data deficiencies 2 years or historical data but mode stable
Property differentiate result be unstable user, its history power mode is copied the reasonable sex determination of data and is not had very strong ginseng to current collection
Examine meaning.Once for this reason, the outlet power consumption situation that significantly bust or paddy electricity proportion are uprushed, need to being classified as and treat that core plagiarizes family.
In above-mentioned flow process, key problem to be solved includes：
(1) definition of zero power power mode and decision method：For current moon total electricity consumption be in zero and nearly 2 years no
Steal electrographic user, whether need according to it is that zero power mode user determines a need for carrying out core to it further
Copy.
(2) judgement of electricity consumption mode stability：User only to electricity consumption mode stable, pre- based on history moon electricity consumption data
The current moon power consumption scope recording just has the meaning that Anomaly criterion copied by collection.
(3) evaluation method of current power consumption zone of reasonableness：To the user being judged to electricity consumption mode stable, need further according to
Estimate the zone of reasonableness of its current power consumption according to history electricity consumption data, and then check that whether collection copies gained power consumption in zone of reasonableness
Interior, thus judge whether data copied by collection abnormal.
Below concrete grammar is proposed to above three problem.
(1) definition of zero power power mode and judgement：
It is one of following three kinds of situations that zero power power mode refers to user's moon power consumption：
(1) it is chronically at the low value close to null value.Investigate the moon electricity consumption value of first 6 months in case, meet and recognize during following formula
For being zero power power mode
(2) recurrent fluctuations and often occur the moon always positive active energy be zero or close to zero low value.In this regard, using as follows
Variance decision method
(3) same period last year is the low value electricity consumption close to null value
If set the k-th user's moon same period last year always positive active enter an item of expenditure in the accounts electricity asThen this criterion is
If belonging to above-mentioned three kinds of situations then it is assumed that current total forward direction active energy belongs to close to (or being equal to) zero compares calibration
Normal phenomenon, therefore and then have or not according to nearly half a year to check to determine a need for core for normal record and copy；If conversely, being not belonging to
Above-mentioned three kinds of situations and of that month active energy are close to (or being equal to) zero then it is assumed that being abnormal null value, being judged to immediately treat that core is plagiarized
Family.
(2) the current moon power consumption zone of reasonableness method of estimation：
Electricity consumption mode stable sex determination is directed to current power consumption non-zero and the history electricity consumption data user of full 24 months.To with
The stable user of power mode, power consumption reasonable interval as obtained by historical data prediction just has the meaning that electricity Anomaly criterion copied by collection
Justice.For above-mentioned purpose, with 12 months months coefficient (moon, total active energy accounted for the ratio of 12 monthly average moons total active energy)
Define electricity consumption mode time sequence, electricity consumption mode stability is judged using grey Relational Analysis Method.
Hereinafter note user is I in the 1st～12 month in the past, and past the 13rd～24 month was ii year.Steady with power mode
Qualitative analysis is carried out by following flow process：
(1) history moon power consumption is converted under basic air temperature
The basic air temperature of the m monthIt is defined as the local temperature on average corresponding to month for many years.Will power consumption conversion month by month
To under basic air temperature, it is the impact in order to reject 2 years temperature differences to month coefficient Time Series Similarity.
First with the daily power consumption data of the last summer (6～September), winter (2 months December～next years), calculate and use
Family k summer, day in winter active energy, with regard to the sensitivity coefficient of daily mean temperature, are designated as ε respectivelyk SMAnd εk WT.If y (y=
I, II) the m month actual monthly mean temperature average beThen this month power consumption convert formula is：
In formula, ny,mNumber of days for the y m month；εk,mFor temperature sensitivity coefficient, the m month is to take during summer (winter) moon in season
εk SM(εk WT), can use 0 during spring and autumn month.
(2) calculate month coefficient
It is worth to over month coefficient (y=I, the II of 24 months according to the conversion under fiducial temperature；M=1 ... 12)
(3) seek the degree of association of in month, two coefficient sequence
Define two electricity consumption mode time sequences x of user k with I, II month coefficientk,I={ xk,I(1)…xk,I
} and x (12)k,II={ xk,II(1)…xk,II(12) }, they constitute two factor sequences of correlation analysis.For judging both
The degree of association, first calculates the maximum difference in the two poles of the earth and lowest difference
Secondly, to factor calculate correlation coefficient each in factor sequence
Wherein Δk(i)=| xk,I(i)-xk,II(i)|
In formula, ρ ∈ [0,1] is resolution ratio.
Average to user's k calculate correlation coefficient
By ΔkIt is judged to mode stable more than the user of threshold value.
(3) moon power consumption reasonable interval Forecasting Methodology：
The user in predicting current moon power consumption reasonable interval being stable to electricity consumption mode decision.Including following two steps：
(1) predict user's power consumption grey of current moon estimate
Press month Y-factor method Y prediction power consumption of the current moon first
Wherein,It is the monthly then electricity demand forecasting obtaining after on monthly, the upper two power consumption weighted average to user k
Value；M0For current corresponding month；It is to user k M upper two year0What after month month coefficient weighted average, prediction obtained works as
Month phase coefficient.
It was the same period upper two year monthly temperature weighted mean that above formula gained predicted value may be regarded as current monthly temperatureWhen the moon
Power consumption.Therefore according to current actual monthly temperatureAs the following formula to current moon power consumption grey estimate correction
(4) the current moon power consumption zone of reasonableness method of estimation：
First of that month benchmark electricity is defined to user, it is according to user's history power mode, of that month power consumption to be made
Predicted value, be predicted using month Y-factor method Y, concretely comprise the following steps：
1st step：Calculate active energy of each moon in year of retrodicting with respect to year ratio of monthly average power consumption of retrodicting that it is located.To
K user retrodicts for l-th the m month in year, and result of calculation is designated as βk,l,m.
2nd step：Calculate the average of month same period coefficient, to k-th user's m month
3rd step：The total electricity consumption in the prediction current time that is located, adopts average weighted method for this, and gives more in recent years
Part electricity consumption value with larger weight, so having
4th step：Predict current power consumption, computing formula is
5th step：Current power consumption is modified, to obtain current benchmark electricity.Implement this step be in view of above formula prediction
The current power consumption of gained can be regarded as current monthly mean temperature equal to pre- under 2 year same period monthly mean temperature weighted mean in the past
Measured value, and current actual monthly mean temperature may deviate, and needs according to temperature deviation value and user power utilization sensitivity system for this
Several current power consumption is modified, with count temperature fluctuation impact.Based on appeal thought, k-th user current benchmark electricity
Measuring computing formula is
After determining the benchmark electricity of each user, define core by certain deviation range of benchmark electricity and plagiarize family this month power consumption
Zone of reasonableness.If k-th user of note is distinguished with the maximum of actual value deviation amplitude and minimum of a value in passing 6 months predicted values
ForWithThen the zone of reasonableness of this user current forward direction active energy isWherein the upper bound and lower bound are pressed
