Description
Technical field
Present invention relates particularly to the new real-time electricity anti-theft method of one kind.
Background technology
With the development and the improvement of people's living standards of national economy technology, electric energy has become people's production and raw
Essential secondary energy sources in work, the production and life given people brings endless facility.Electric power is as a kind of invisible
Commodity, are the essential consumer goods of modern society.The electricity charge and electric power meter that user power utilization must be checked and approved according to country
Record electricity payment on time.At present, China's theft electric energy phenomenon becomes worse, and makes the electricity already extremely protruded
Power imbalance between supply and demand is more sharp, and it destroys electricity consumption order, has upset economic environment, seriously compromises the economic effect of power supply enterprise
Benefit.The work of electricity anti-stealing carried out for various electricity filching means is a vital task of power monitoring department and power supply enterprise.
Severe investigation with power monitoring department to electricity stealing, current electricity stealing is more and more hidden.Current
Electricity stealing is broadly divided into two classes, and one is that, for the stealing in ammeter, current many electricity stealings are to change structure inside ammeter
Carried out on the basis of making, such as decompression, under-voltage stealing, CT short circuits or open circuit stealing, phase sequence circuit in change table, stuck dial plate,
Change the stealing modes such as transformer.For electricity stealing in table, currently have more novel intelligent electric meter and come into operation and obtain
Good result.Two be for the stealing outside ammeter, such as without apply to install register one's residence if the wiring use on the circuit of power supply department privately
Electricity, or there is table user to get rid of table electricity consumption privately, this class behavior is more than that the power loss of power department can be caused, while be also possible to by
In private draw disorderly connect with random electricity consumption and cause circuit and public change overload to damage, easily cause personal injury and cause fire etc.
Major accident occurs.The mode of current anti-off-balancesheet stealing is mainly the electric energy or electric current of the electric energy or electric current and point table that compare summary table
Whether sum is consistent, and difference is exactly the presence of electricity stealing beyond threshold value, but is due to have certain between summary table and each point of table
Distance, wire cross-section area, material, the mode of connection etc. can all influence the numerical value in table, at the same ammeter can also exist in itself it is certain
Electric energy loss, therefore it is this to record numerical value it is related Comparison Method it is thief-proof electrically very immature in actual applications, technology
The electricity of loss or the deviation of data record can all influence correct judgement.
The content of the invention
Judge the precisely simple and effective new anti-electricity-theft side in real time of reliable, method it is an object of the invention to provide one kind
Method.
This new real-time electricity anti-theft method that the present invention is provided, comprises the following steps：
S1. when electric power networks are normally run and are occurred without stealing, electric power networks are formed according to the power information of reporting of user
Theoretical bus admittance matrix；And when the power information of user updates, then the theoretical bus admittance matrix of electric power networks is also real-time
Update；
S2. in power network actual motion, each nodal terminal of scanning power network accesses the state of power network, obtains power network actual motion
When each node self-admittance and transadmittance, so as to form the actual node admittance matrix of electric power networks；
S3. the obtained theoretical bus admittance matrix of the obtained actual node admittance matrixs of step S2 and step S1 is contrasted,
So as to determine whether stealing.
The theoretical bus admittance matrix of acquisition electric power networks described in step S1, specially obtains node using following steps
Admittance matrix：
A. respective power information data of reporting of user；
B. according to the power information data of reporting of user, judge each branch road of electric power networks whether with the presence of power consumer；
If C. certain branch road is with the presence of power consumer, calculates the self-admittance of the branch road first and last node and transadmittance and stored；
If certain branch road does not have power consumer presence, the self-admittance of the branch road first and last node and transadmittance are designated as 0 or are not present；
D. the bus admittance matrix of power network is obtained.
The state of scanning power network each nodal terminal access power network described in step S2, is specially to be copied by the collection of each node
Device is scanned.
Actual node admittance matrix and theoretical bus admittance matrix being contrasted and determined whether described in step S3
Stealing occurs, and is specially judged using following rule：
If the exponent number of actual node admittance matrix is less than or equal to the exponent number of theoretical bus admittance matrix, it is determined as no stealing hair
It is raw；
If the exponent number of actual node admittance matrix is more than the exponent number of theoretical bus admittance matrix, it is determined as there is stealing.
This new real-time electricity anti-theft method that the present invention is provided, using the bus admittance matrix of region electric power networks to this
The load in region is monitored in real time, judges that the region whether there is electricity stealing；As a result of power state Comparison Method, do not have
Numerical computations problem is related to, therefore substantially increases accuracy of detection, it is to avoid understatement or wrong report electricity stealing occurs, and
Intuitively it can be judged according to network state；While the method by monitoring in real time, when there is electricity stealing, electric power prison
Pipe portion door can be responded immediately, accurately and easily determine stealing place, reduce energy loss.
