Accompanying drawing in bright embodiment, is clearly and completely described the technical scheme in the embodiment of the present invention,
Obviously, described embodiment is a part of embodiment of the present invention rather than whole embodiments.Based on
Embodiment in the present invention, those of ordinary skill in the art are obtained under not making creative work premise
The every other embodiment obtained, broadly falls into the scope of protection of the invention.Reference table identical in accompanying drawing
Show the same or analogous element of function.Although the various aspects of embodiment shown in the drawings, but remove
Non-specifically is pointed out, it is not necessary to accompanying drawing drawn to scale.
The embodiment of the present invention provides a kind of method that multiplexing electric abnormality is analyzed, shown in Figure 1, including step
101-104:
Step 101: obtain power information, and be that each class sub-information distribution in power information refers to accordingly
Mark weight;Power information includes the sub-information of logout, electricity quantum information, the sub-information of load and line loss
A class in information or multiclass.
Preferably, power information includes at least the two sub-information of class.In the embodiment of the present invention, to above-mentioned electricity consumption
Information is classified, and specifically can be divided into event class, electricity class, load class, line loss class etc., relatively
The sub-information of logout, electricity quantum information, the sub-information of load and the sub-information of line loss that should be above-mentioned.Meanwhile,
Distribute corresponding index weights for the sub-information of each class in power information, judged by default index
Multiplexing electric abnormality degree.Concrete, can with the embodiment of the present invention utilizes multiplexing electric abnormality suspicion index (ELI,
Electric Larceny Index) assess the multiplexing electric abnormality degree of user, the highest then multiplexing electric abnormality of index is disliked
Doubt bigger.Such as, ELI, in terms of full marks 100 points, can distribute event class, electricity class, load class, line
Damage class index weights in the overall evaluation and be respectively 40%, 40%, 10%, 10%.
Step 102: judge whether the sub-information of each class in power information exists corresponding multiplexing electric abnormality respectively
Suspicion data.
Owing to power information can include the sub-information of many middle classifications, therefore information sub-to every class respectively is needed to enter
Row judges, it may be judged whether there are multiplexing electric abnormality suspicion data.It is big owing to the sub-information of every class all may comprise
Amount data, therefore and may incessantly there are multiplexing electric abnormality data in the sub-information of each class.
Step 103: when the sub-information of one type exists corresponding multiplexing electric abnormality suspicion data, for default
Multiplexing electric abnormality suspicion index increases the preset increments corresponding with multiplexing electric abnormality suspicion data, and such sub-letter
The preset increments sum of breath is not more than the Maximum Index value that the index weights of such sub-information is corresponding.
In the embodiment of the present invention, pre-setting multiplexing electric abnormality suspicion index, this multiplexing electric abnormality suspicion index has
There is initial value, typically this initial value can be set to zero, it is also possible to be set to other values.Meanwhile, as
Upper described, owing to the sub-information of each class and may exist multiplexing electric abnormality data incessantly, therefore this is preset and increases
Measure corresponding with multiplexing electric abnormality suspicion data.Such as, electricity consumption is being judged whether according to electricity quantum information
During abnormal data, can be according to the daily power consumption E of n days of electric energy meter recordiAnd meansigma methods AvgE is next
Judge, as the daily power consumption E of i-th dayiAnd the difference between this meansigma methods AvgE is preset more than one
Difference time, then may determine that i-th day and there are multiplexing electric abnormality data, the daily power consumption E of i.e. i-th dayiCorresponding
One multiplexing electric abnormality data;Meanwhile, the daily power consumption E in i+1 skyi+1And the difference between AvgE also may be used
The difference can preset more than this, then daily power consumption Ei+1Can also corresponding multiplexing electric abnormality data.Then in step
According to two above-mentioned multiplexing electric abnormality data, multiplexing electric abnormality suspicion index is increased by two accordingly in rapid 103
Preset increments.
Meanwhile, to be not more than the index weights of such sub-information corresponding for the preset increments sum of such sub-information
Maximum Index value;That is, even if there are a large amount of multiplexing electric abnormality data, only according to this in a certain sub-information of class
The electrical anomaly suspicion index that the sub-information of class can increase also is limited, and maximum is less than such sub-information
The Maximum Index value that index weights is corresponding.Such as, multiplexing electric abnormality suspicion index full marks are 100, and initial value is
Zero, the index weights of the sub-information (i.e. electricity quantum information) of electricity class is 40%, then electricity quantum information refers to
The Maximum Index value marking weight corresponding is 100 × 40%=40;If the n (100=60) according to electric energy meter record
It daily power consumption EiAnd meansigma methods AvgE carries out judging whether multiplexing electric abnormality data, if its
In the E of 25 daysiAnd the difference between this meansigma methods AvgE is more than a default difference, and each is used
Preset increments corresponding to electrical anomaly data is 2, then after multiplexing electric abnormality suspicion index is increased preset increments,
This multiplexing electric abnormality suspicion index can be 0+2 × 25=50;But the preset increments due to the sub-information of each class
Sum is not more than the Maximum Index value that the index weights of such sub-information is corresponding, electricity information index weight
Corresponding Maximum Index value is 40, therefore this multiplexing electric abnormality suspicion index is finally defined to 40.
Step 104: when multiplexing electric abnormality suspicion index is more than predetermined threshold value, determines and there is multiplexing electric abnormality event.
In the embodiment of the present invention, determining that the multiplexing electric abnormality suspicion data that the sub-information of each class exists are corresponding
Preset increments adds up, and increases in multiplexing electric abnormality suspicion index ELI, if the electricity consumption after Lei Jia is different
Often suspicion index is more than predetermined threshold value, then explanation power information comprises too much multiplexing electric abnormality suspicion data,
Therefore may determine that and there is multiplexing electric abnormality event.
The method that a kind of multiplexing electric abnormality that the embodiment of the present invention provides is analyzed, presets multiplexing electric abnormality suspicion index,
By power information being carried out classification indicator of distribution weight, determine electricity consumption respectively according to the sub-information of each class
The abnormal the most corresponding preset increments of suspicion data, and this multiplexing electric abnormality suspicion index is increased corresponding presetting
Increment, when the multiplexing electric abnormality suspicion index after cumulative is more than predetermined threshold value, i.e. may determine that and there is electricity consumption
Anomalous event.The method power information is carried out classification and indicator of distribution weight, such that it is able to according to electricity,
Event, load and line loss information carry out comprehensive analysis and judgement, accurately search multiplexing electric abnormality degree higher
User, and greatly reduce investigation difficulty, improve the work efficiency of Utilities Electric Co. power utility check personnel.
Preferably, as shown in above-mentioned steps 102, information sub-to every class judges respectively.Concrete,
In the embodiment of the present invention, the sub-information of logout include decompression event, full decompression event, disconnected phase event,

During information sub-including logout, step 102 judges respectively according to the sub-information of each class in power information
Whether there are multiplexing electric abnormality data, specifically include:
The start time electricity consumption data that in step A1, respectively the acquisition sub-information of logout, each event is corresponding
With finish time electricity consumption data, and determine corresponding power change values;
Step A2, power change values more than predetermined power changing value time, determine that this event exists electricity consumption
Abnormal data.
Such as, the sub-information of logout comprises the relevant information of decompression event, then in step A1
With determine the time started of decompression event, end time and start time electricity consumption data (as voltage,
Electric current, power etc.) and the electricity consumption data (voltage, electric current, power etc. can also be comprised) of finish time;
Before and after i.e. may determine that this decompression event of generation according to start time electricity consumption data and finish time electricity consumption data
Power change values.Meanwhile, may determine that decompression event according to decompression event start time and end time
Duration, step A2 determines the power change values under normal circumstances in identical duration
(as predetermined power changing value), at power change values and the power under normal circumstances of decompression event
When difference between changing value is excessive, (power change values such as decompression event becomes than power under normal circumstances
Change value more than 20% with first-class), then may determine that and there are multiplexing electric abnormality data, and then may determine that corresponding
Preset increments, and perform multiplexing electric abnormality suspicion index is increased by step 103 process of this preset increments.
Or, step 102 judges whether multiplexing electric abnormality data according to the sub-information of logout, tool
Body includes:
Step A3, determine the time of origin of each event in the sub-information of logout respectively, and determine first
Freeze electricity in preset time period the day of every day, and the time of origin of event is positioned at the first preset time period;
Step A4, the difference freezed two continuous print days between electricity more than preset freeze electricity difference time,
Determine that this event exists multiplexing electric abnormality data.
Concrete, what electric energy meter typically can store 62 days (two months) freezes electricity, in this event day
Record the time of origin of sub-information corresponding event within 62 days, then can perform step A3-A4.Such as,
Comprising the relevant information of decompression event in the sub-information of logout, the time of origin of this decompression event is ten days
Before (i.e. within 62 days), then can obtain this decompression event and the same day and the previous day and rear one occur
They totally 3 days (the i.e. first preset time period is 3 days) day freeze electricity, respectively Ei、Ei-1And Ei+1。
At difference (the i.e. E freezed day between electricityiWith Ei-1Between difference or EiWith Ei+1Between difference)
More than preset freeze electricity difference time, determine that this event exists multiplexing electric abnormality data.
It should be noted that when judging whether multiplexing electric abnormality data according to the sub-information of logout,
Above-mentioned steps A1-A2 can be only included, it is also possible to only include step A3-A4, it is also possible to include step simultaneously
Rapid A1-A4.Generally individually can bring the change of power or power consumption during due to generation anomalous event, therefore pass through
Change to power change values or the day amount of freezing can determine whether there is multiplexing electric abnormality number more accurately
According to.

Step B4, at AvgEh and EiBetween difference more than the second preset difference value time, determine i-th day and deposit
In multiplexing electric abnormality data;Wherein, i=1,2,3 ... n, n are the natural law that the second preset time period comprises.
Wherein, freeze electricity bimestrial day owing to local electric energy meter typically may only preserve, history same period
Daily power consumption can be obtained by main station system.By by daily power consumption E theniWith history same period (as
Last year on corresponding date, or the most corresponding date etc. the year before last) meansigma methods compare, it is also possible to determine
Daily power consumption E theniThe most abnormal.Simultaneously as daily power consumption then and history same period is daily
Both there is normal error in electricity itself, therefore generally, the second preset difference value is more than above-mentioned first
Preset difference value;It can also be provided that it is identical.
Or, judge whether multiplexing electric abnormality data according to electricity quantum information, including:
