Classified with FCM algorithm to user load characteristics；(3) electric energy consumption terminal electrical load characteristics again are obtained, and to it
It is identified with power mode.
Wherein, the key step of FCM algorithm is as follows:
1) it initializes.If cluster classification number is c (2≤c≤n, n are number of samples), iteration stopping threshold values ε and iteration are set
Counter b=0 initializes subordinated-degree matrix U(0)；
2) cluster centre matrix P is updated with formula (1)(b):
3) subordinated-degree matrix U is updated with formula (2)(b+1):
4) judge whether | | U(b)-U(b+1)| | < ε, if so, algorithm stops, output matrix U and P.Otherwise b=b+1 is enabled,
Step 2 is gone to continue to execute.Wherein | | | | it is certain suitable matrix norm.
After algorithm iteration stops, the form of finally obtained degree of membership and cluster centre is respectively as follows:
Wherein clustering belongs to unsupervised learning, and the data object for being mainly reflected in clustering learning does not have category label,
It needs to be calculated automatically by cluster learning algorithm, i.e., by the set-partition of a data unit at several sons for being known as cluster or classification
Collect, the data in each class have similitude, its partitioning standards are exactly " things of a kind come together, people of a mind fall into the same group ".The principle of clustering foundation is to make
It is same cluster in object there is similitude as big as possible, and it is different cluster in object there is diversity as big as possible,
Clustering mainly solves the problems, such as to be how under the premise of no priori knowledge, realizes and to meet clustering for this requirement
Polymerization.
All kinds of under certain industry use power mode to clustering for identification, right using Fuzzy C-Means Cluster Algorithm (FCM)
The part throttle characteristics of every profession and trade is classified.FCM clustering algorithm is that one kind is gathered with degree of membership to determine that each data point belongs to some
The algorithm of class degree, it is maximum that it makes to be divided into similarity between the object of same cluster, and the similarity between different clusters is minimum.
FCM algorithm is the improvement of common C mean algorithm, and common C mean algorithm is rigid for the division of data, and FCM is then one
Kind fuzzy division flexible.When cluster is related to the fuzzy boundary between things, the classifying quality of Fuzzy Cluster Analysis method is more
It is good.
(2) the other stealing mode knowledge base of universal class is established
By constructing the other stealing mode knowledge base of universal class, the other stealing mode laboratory reproduction of universal class is realized.It is as shown in Figure 3:
Determine stealing case knowledge source.The method combined using documents and materials, expert investigation, field research, to stealing
Case, especially electrified energy-consuming terminal industry stealing case is arranged again；And to the stealing mode in stealing case
It is studied, is aggregated into the written historical materials of generalities.

The response characteristic of electric behavior excavates potential stealing mode and stealing mechanism；It further verified according to historical data, improve theory
Model improves the science, reliability, applicability of theoretical model.
Common stealing mechanism is as follows: by the basic measuring principle and electrical power calculation formula of electric energy meter
It is found that the correct metering of electric energy meter is mainly determined by voltage, electric current, power factor, installation and the correctness of wiring.Stealing user
Influencing a certain link therein by artificial means makes slack-off electric energy meter revolving speed, stalling or even reversion, to achieve the purpose that stealing.
Mainly stealing electricity method includes:
Under-voltage method stealing.Stealing user passes through the voltage circuit of reclosing electric energy meter, is open circuit by voltage circuit reconfiguration
Or make voltage circuit poor contact, so that the either collection voltages value decline of electric energy meter potential winding decompression, this
Sample can reach the stealing purpose disregarded or lack quantity calculation.Its means mainly includes causing voltage circuit open circuit, causing voltage circuit
Poor contact failure, the decompression of voltage circuit series resistance and change voltage circuit connection.
Defluidization method stealing.Stealing user changes current transformer by changing electric energy meter method of current circuit connection
Polarity and no-load voltage ratio, short circuit current mutual inductor secondary circuit lead to electricity so that secondary circuit generates failure in electrical energy measurement
The current reduction passed through on current coil in energy gauge table even absolutely not, and then causes electric energy meter to be counted less even
Not quantity calculation.Its means mainly includes that change current circuit connection (exchange, will indoor ground by such as single-phase electric energy meter phase line and the neutral conductor
Line or neighbours' neutral conductor as the neutral conductor, adjunction by-pass line make part meet electric current around more electric energy meter etc.), change current transformer
No-load voltage ratio makes current loop open circuit, short circuit current circuit etc..
Phase-shifting method stealing.The mode of connection or misphase that stealing user passes through change electric energy meter voltage or electric current secondary loop
Electric energy meter coil voltage, electric current are accessed, and utilizes inductance or the specific connection of capacitor, to change the sampling of electric energy meter interior loop
Voltage, electric current and phase relation so that the phase relation between voltage and electric current is different with the phase relation normally measured, from
And cause electric energy meter that can not correctly measure practical electricity consumption.Its means mainly includes changing voltage circuit wiring, changing electric current time
Road wiring is that electric energy meter accesses negative-phase sequence curent, electric energy meter reversion is caused by external power supply, passes through by current transformer or transformer
Phase shifter changes voltage and current phase etc..
Distributed photovoltaic stealing mechanism.The simplified pinciple figure of distributed photovoltaic power generation is as shown in Figure 6.Photovoltaic array component is real
Direct current is exported after applying photoelectric conversion, then is converted to the alternating current for meeting power quality requirement through inversion and its filter.Turn
The alternating current become is preferentially for local load consumption, and extra electric energy is conveyed to power grid, from power grid power purchase when workload demand is big.?
The output end of photovoltaic DC-to-AC converter and photovoltaic ammeter and the critical point for being mounted with energy bidirectional measuring respectively with the connecting pin of public electric wire net
Ammeter.
Distributed photovoltaic stealing is mainly by the illegal transformation to photovoltaic power generation equipment and route, so that photovoltaic ammeter turns
Speed is accelerated, and more false generated energy are included in, to gain more photovoltaic subsidies by cheating.Typical distributed photovoltaic stealing is as follows:
1) boosting method

2) method is flowed up
Up-flow method photovoltaic stealing mode simplified pinciple figure is as shown in Figure 8.Very little voltage is added in primary side using pressure regulator, i.e.,
Biggish electric current can be induced on secondary side, be equivalent on the current loop of photovoltaic table additional one and increase emptily electric current, make gauge table
Faster rotational speed, more photovoltaic power generation quantities that record are to gain national electricity price subsidy by cheating.
3) alternating current reconfiguration method
Alternating current reconfiguration method photovoltaic stealing mode simplified pinciple figure is as shown in Figure 9.Adjust back panel wiring mode, by photovoltaic table into
Line reconfiguration is to alternating current inlet wire, so that the data that ammeter is measured are the power consumption of load.This stealing mode disappears in user's alternating current
In the case that wasted work rate is greater than photovoltaic generation power, subsidy can be gained, such as when there is no light, user can be by the electric energy of load consumption by cheating
All pretend to be the generated energy of photovoltaic generating system.
4) photovoltaic simulator method
Photovoltaic simulator method photovoltaic stealing mode simplified pinciple figure is as shown in Figure 10.Stealing user directly utilizes power electronics
Commercial power rectification at direct current, is parallel to the DC side of photovoltaic generating system by fairing, is converted to exchange by photovoltaic DC-to-AC converter
Electricity online.Using this stealing mode, user even can not install photovoltaic battery panel, directly pretend to be photovoltaic cell with fairing
Plate.
