Description

Real-time monitoring system for preventing electricity theft for power network
Technical field:
The present invention relates to a kind of electricity anti-theft method and device, particularly a kind of anti-electricity-theft from the mains side management, look into the method and the device of stealing from the system side analysis.
Background technology:
Mainly there are following problems in current existing preventing electricity theft for power network mode:
1, be primarily aimed at 0.4kV user side measuring apparatus and protect, but stealing electricity method reaches thousands of kinds, just can't effectively not take precautions against by the electricity filching behavior of measuring apparatus.Therefore, any technological prevention measure at single measuring apparatus can't prevent effectively that all electricity filching behavior from taking place;
2, traditional anti-electricity-theft inspection mainly relies on the generaI investigation of artificial business, and poor in timeliness, generaI investigation are not in place, is difficult to grasp in real time the operation conditions of power distribution network, the time, place and the related data that accurately provide electricity filching behavior to take place, and verification is difficult.
3, existing line Loss Analysis for Power Distribution Network system, can only provide the line loss of whole piece feeder line, and can not provide in the feeder line line loss of branch road and node arbitrarily, so, all can't finish the comprehensive line loss analyzing of total system alone based on the line loss analysis system of power automatic system.
Summary of the invention:
Purpose of the present invention is to provide a kind of anti-electricity-theft from the mains side management, looks into the method and apparatus of stealing from the system side analysis.Apparatus of the present invention merge advanced mutual inductor technology, the information processing technology, modern communications technology and Computer Analysis technology, emphasis carries out omnibearing, real-time monitoring to 10kV distribution network and transformer outlet summary table, forms an independent monitoring system from transformer station, power distribution network backbone to sub power distribution branch line, substation transformer; The data of simultaneously can the remote copying user measuring summary table, or the related data in the systems such as fusion electricity consumption marketing, load control, and carry out the analysis and the processing of system on this basis, find out lossy line road, high loss electricity consumption point, the user of stealing suspicion accurately and this user's electricity consumption real-time parameter is provided for the supervision of power consumption personnel, particularly stealing time, power-steeling quantity etc., thereby for preventing stealing, investigating and prosecuting that stealing provides a great convenience and foundation accurately.
Apparatus of the present invention are made up of low-voltage electric energy acquisition terminal, high voltage electric energy acquisition terminal, safety monitoring terminal, Surveillance center and mobile electricity consumption supervisory terminal.Wherein the low-voltage electric energy acquisition terminal is divided into two classes: distribution transforming acquisition terminal and electric energy acquisition terminal.Concrete which kind of low pressure acquisition terminal that adopts needs to decide according to the actual conditions of monitoring point, if the measuring apparatus of monitoring point has data-interface, then adopts the electric energy acquisition terminal to get final product; Otherwise need to install the distribution transforming acquisition terminal that has combination transformer.
High voltage electric energy acquisition terminal in apparatus of the present invention, the acquisition mode of low-voltage electric energy acquisition terminal are different with the installation site: the high voltage electric energy acquisition terminal is made up of add high pressure electrical energy parameter acquisition module, system data processing module, communication module etc. of three single-phase high voltage current transformers or three single-phase high voltage current/voltage combined instrument transformers, need not rely on original measuring apparatus and independent the load parameter of power distribution network 10kV (35kV) side is gathered, and the installation site is very flexible, and feeder line, node, platform change high-pressure side all can be installed in the electrical network.The electric energy acquisition terminal of low-voltage electric energy acquisition terminal is made up of subscriber's meter pulse collection module or subscriber's meter intelligent acquisition module, system data processing module and communication controller, be installed in the secondary outlet side of metering mutual inductor, be between mutual inductor and the measuring apparatus, by RS485 or pulse interface the data of measuring apparatus are gathered, also can make up low-voltage electric energy parameter acquisition module in case of necessity and finish power consumption parameter is gathered.The distribution of low-voltage electric energy acquisition terminal becomes monitoring terminal and is made up of low pressure combination transformer, low-voltage electric energy acquisition module, system data processing module, communication control module and outdoor collection cabinet, combination transformer is installed on the substation transformer low-tension bushing, gathers cabinet and is installed on the platform power transformation bar.The transformer operational factor is gathered the parameter that to gather the multiple metering souvenir simultaneously by combination transformer.The parameter of each acquisition terminal collection is all carried out data preservation, electric weight statistics, data analysis processing, report output and failure message warning and can in time be notified the supervision of power consumption personnel by mobile electricity consumption supervisory terminal to Surveillance center by the teletransmission of GPRS digital mobile communication network, for in time handling the measuring apparatus fault, prevention and investigation electricity filching behavior, the accuracy of assurance electric energy metrical provides the information channel of quick response.
The weak signal punching high-voltage mutual inductor that uses in the high voltage electric energy acquisition terminal in apparatus of the present invention is finished the conversion of electric current, voltage signal and is responsible for providing the power supply energy of high-pressure side circuit.
Apparatus of the present invention any anti-electricity-theft product different from the past at single measuring apparatus or single stealing technological means, according to the anti-electricity-theft thought of system, include multistage, networking, the high-low pressure parameter complementation of transformer station, feeder line, branch road, node, transformer and the whole distribution system of user side, the independent collection and anti-electricity-theft monitoring system that remote meter reading combines.Initiate in addition at high pressure feeder line end user's electricity consumption situation is monitored, make the measuring apparatus that the monitoring of user power utilization no longer is confined to user side, and can carry out in the place away from the user, leading-out terminal that also can transformer carries out, thereby prevents sabotaging of disabled user effectively, for banning stealing, reduce electricity charge loss to greatest extent, reduce line loss, avoid unnecessary dispute, practicable advanced technology means are provided.
