Description
Technical field
It opposes electricity-stealing method the present invention relates to power pack, and in particular to a kind of anti-specially to become user's discontinuous form stealing electricity method.
Background technique
It opposes electricity-stealing an important process of always power supply department.The traditional method of opposing electricity-stealing of power supply department, which relies primarily on, patrols
Inspection patrolman has found stealing clue, inefficiency, the timeliness opposed electricity-stealing, validity by power consumer site inspection
It cannot obviously meet the needs of, once especially specially becoming user's stealing, be more difficult to investigate and prosecute using existing means, because specially becoming user's
The equipment such as transformer are customer capital, and the installation site of metering device is in user's compass of competency, and are configured with and have mostly
The professional electrician of respective electric knowledge so that it is more hidden and professional specially to become user's electricity stealing, and mostly uses discontinuous form stealing
Method, once electricity stealing occurs, power-steeling quantity is big, and harm is serious.
In recent years, anti-discontinuous form stealing electricity method has been shown in research, such as the Chinese patent literature of Publication No. CN103455855B
A kind of intermittent electricity stealing prevention detection method based on the analysis of power information data is disclosed, the problem is that: first, calculating
Method is complicated, time-consuming and has certain limitation, second, being only applicable to the intermittent electricity stealing of detection meter power loss；
Third, not having automatic calculating power-steeling quantity function.
In recent years, carrying forward vigorously with state grid corporation of smart grid construction, Open3000 system, D5000 system
(upgrade version of Open3000), power information acquisition system and marketing system are built up and put into operation in succession, and power grid is in real time and non real-time
Information is highly integrated, shared and utilize, and provides comprehensive, complete and fine electric power industry for operations of power networks at different levels and administrative staff
Business data flow.Power supply management department can inquire the electric current of power supply line, electricity by Open3000 system and/or D5000 system
The real time datas such as pressure, electricity and historical data；The daily loss of inquiry power supply line is convenient to by power information acquisition system
Electricity, line loss per unit, the electricity consumption of each power consumer, electric current, voltage etc. in real time and history electricity consumption data information, pass through marketing system
It is convenient to the essential informations such as contract capacity, user location and the identity of inquiry power consumer.How above system is efficiently used
And information, it is that power supply department currently puts forth effort the technology for wanting to solve that building is timely and effectively anti-, which specially to become user's discontinuous form stealing electricity method,
Problem.
Summary of the invention
The object of the present invention is to provide a kind of anti-specially change user's discontinuous form stealing electricity method, this method in time, accurately to lock

In formula, WDThe electricity consumption of day D acquisition is mutated specially to become user in line loss；WD-1Day D is mutated specially to become user in line loss
Proxima luce (prox. luc) acquisition electricity consumption；
5. specially becoming in user from the doubtful stealing of extraction, screens and locks stealing and specially become user:
The first step transfers the target line and doubtful stealing of line loss mutation day D from power supply department power information acquisition system
24 hours current datas for specially becoming user, with 5 minutes for interval synchronization sampled targets line current inSpecially become use with doubtful stealing
Family electric current Ιn；
Second step calculates doubtful stealing using formula (4) and specially becomes user in the electric current bust value △ I of line loss mutation day Dn；It adopts
Doubtful stealing, which is calculated, with formula (5) specially becomes user in the electric current bust percentage K of line loss mutation day Dn:
△In=Ιn-1-In (4)
In formula, ΙnSpecially become user in the present sample current value of electricity bust day, I for doubtful stealingn-1It is special for doubtful stealing
Become user in electricity bust day and present sample current value ΙnAn adjacent upper sampled current value；
Third step, if a certain doubtful stealing, which specially becomes user, has △ In>=15 amperes or Kn>=10% situation, then count
Calculate the △ InThere is the current variation value of the affiliated power supply line of time point, if power supply line is in the △ InThere is the curent change of time point
Value does not occur △ InThe electric current bust of size, then lock the doubtful stealing and specially become user and specially become user into stealing；
6. specially becoming the power-steeling quantity that user needs to remedy using the stealing that formula (6) and formula (7) calculate locking:
In formula: η is specially to become user's stealing ratio, and △ I is the abovementioned steps 5. middle △ I calculatednMaximum value in value, ITFor
Stealing specially becomes the current value that user acquires after electric current bust, WFFor the special change user stealing period electricity of acquisition, specially become user
The stealing period terminates since selected electric current bust time point to there is electric current time point of uprushing, WQIt needs to remedy for the stealing period
Power-steeling quantity.
The present invention has the effect of positive: anti-special change user discontinuous form stealing electricity method of the invention, by power supply
Door relevant historical data, which carries out analysis, accurately automatic identification and the discontinuous form stealing locked in power supply line specially to become user,
And quickly, easily and accurately can determine that discontinuous form stealing specially becomes the power-steeling quantity that user need to remedy, accuracy and reliability is higher.
