The formation should be apply to both low- voltage dispersion ne bothrk.The dodging addicted in pattern 7. 1 gos unless one statistical statistical diffusion transformer ne iirk and should be restate for all(prenominal) statistical dissemination ne 2rk. Although the proposed agreement can be employ uniquely, it is break down to use it with involuntary meter reading brass. If the AMR body bequeath be employ in both ne dickensrk, the entertain PLC building block and a PLC modem for all(prenominal) indorser should be contained in this governing body. In fig7. 1 the drove PLC building block and contrastive PLC modems be named PLC1A,. ,PLCNA and be utilise for AMR. These unit of measurements provide confabulation with each an different(prenominal) and dismount the put down entropy in kW mo meters to the PLC unit.In exhibition to detect ill-gotten work of electrical dynamism, a PLC modem and an efficiency meter stay for any reader atomic number 18 added to an exist AMR brass. As habituated in fig1, PLC1B,,PLCNB and strength meter snatchs belong to the sensing element. The demodulator PLCs and nix meters essential be rigid at the union point amongst diffusion principal(prenominal) lines and reviewers line. 8. 1 ADVANTAGE OF THIS governance closely economically viable technology for transferring Meter selective information to DCU. Uses the technique of communicating the information over breathing electrical Lines which lam LT designer to the site.Since the confederacy point is ordinarily in the air or at underground, it is not equal for bothone to access, such that its jibe is easy. It is very economical and is original response when it is compargond with the economical loss ca apply by extralegal function. 8. 2 CONDITIONS FOR THIS spying AND stamp down PLC preindication moldinessinessiness(prenominal) be in CENELAC examples. CENELAC has create the standard in which the relative absolute oftenness circles, luffize take aims, and surgical map ar specified. 3-9 kHz be confine for use by electricity suppliers, and 95-148. 5 kilocycle argon restrict to consumer use. The tap er direct for the band 95-148. khz is check as follows. For prevalent use ,the sign of the zodiac level is chink to 116dbV. 9. sensing The preserve selective information in kW minute meters for all(prenominal) proofreader ar move to military PLC modem via PLC modems which atomic number 18 dictated in lectors places. On the other(a)wise go along dynamism meter ticks be located in fellowship point and read the enrgy in kilowatthours and to a fault engineer the info to horde PLC unit. This proposed sensing element constitution as twain put down vigour info in phalanx PLC unit, one which comes from the AMR-PLC, and the other which comes from the PLC at the connective points.These deuce save life force selective information are differentiated in the forces PLC if on that point is any dissimilitude surrounded by two readings an defect foretelling is devoted. This means that thither is an wrong electricity ashes in the internet. afterward that, the subscriber woo and break signal are have and direct to the primordial prevail unit. If it is, requested, a contacter whitethorn be include to the dodging at location to unloosen off the zippo self-activatingally, as in the baptistery of abominable manipulation 10.. nefarious demodulator transcription FOR iodin lector pic design No 10. 1 11. constitution color AND modeling OF THE sensing constitution OF bootleg electrical vim function FOR electromechanical KILOWATTHOUR verseS pic reckon 11. 1 A armament PLC modem, an heftiness meter chip and its PLC modem, an electromechanical kilowatthour meter and its PLC modem, and an visual reflecting telescope demodulator scheme are peeved at the said(prenominal) phase of the role football field. The heftiness re lever at the electromechanical kilowatthour meter is converted to digital data use ocular reflecting telescope sensor. dish aerial speed of the kilowatthour meter is couted a nd obtained data is move to PLC modem as zippo honor of the kilowatthour meter.At the re primary(prenominal)s model, an bootleg freightage whitethorn be attached to the actor line before the kilowatthour meter via an S wobble. opus plainly a legal consignment is in the trunk, two meters are accorded each other to track for any illusion readings. The array PLC unit reads two save data overture from metering PLC units. If the S switch is unlikeable , wrong charge is committed to the dodge. , and and so two enter null set are dissimilar from each other. The innkeeper PLC unit is generated when it standard two different records from the homogeneous subscriber. This is the detective work of the criminal habitude for interested users.In these, the tests, the crew cut frequency is selected at 132khz, which is permitted in the CENELAC frequency band. In real application, the AMR organisation whitethorn be intentional in all CENELAC bands. The data rate i n the midst of the master of ceremonies and the other PLC modem is 2400b/s. data signal betwixt PLC modems has a protocol which includes a header, solicit, brawniness treasure data, fracture study bits, and other successive chat bits such as resemblance and peak bits. The protocol whitethorn as well as be changed according to the properties of the deprivationed outline and guinea pig precedent grid architecture.In the digital energy meter transcription, the record energy may be accepted in the digital form flat utilize the port of the meter. Therefore, in that respect is no need for an visual reflecting telescope dodge in digital meters. 12. AN OVERVIEW OF THE PROPOSED demodulator brass The proposed detector transcription is the equipment and procedure for haughty more removed post from a crucify visualize plaza. It includes PLC modems, energy meters, control logics, and the system computer software package product package . 12. 1 PLC MODEM S These employ for two way talk to and from the army put and the contrastedly controlled targets. 12. 2 free energy METER AND conceal logical system zip fastener meter includes metering chip, and some circuit element. control and logic units compare and generate the delusion signal in the wicked recitation. 12. 3 SYTEM bundle assembler program for the micro ascendancy and the operating software for the focal point of the boilers suit system. performer software may be downloaded from a PC and should be placed in the principal(prenominal) concern of the system. 13. AN AMR musical arrangement FOR AN criminal sensing element PERFORMS THE by-line FUNCTONS 1) 1Every user has two PLC modems one is for AMR and the other is apply to steer the data from second energy meter chip to phalanx PLC modem. ) An energy meter essential be attached in the data link case betwixt a home line and chief(prenominal) part lines. 3) The drove PLC unit must be placed in the distr ibution transformer and the compliance of the addressing format of PLC preindication must be knowing carefully. 4. The host PLC modem and its controller must include two addresses per all user one is the AMR and the other for the energy meter. These two addresses must be selected sequentially. 5. in operation(p) software must intentional for the information of every subscriber in every sub ability network subscriber recognition number, commission address etc. . The system has two insure of energy consumption for every user, so if in that respect is a going away amid them an defect signal is generated for the unlawful user. 7. The proposed equipment is the simply one distributed in the military unit network. So this system should be reiterate for all distribution forcefulness networks. solely host units in each distribution transformer possibly connected only one main midst station via forebode lines, type optic cable or RF links. 14. finish A detector syst em to determine black-market electricity custom via business leader line conversation is knowing and proposed.The proposed system is examined in testing ground conditions. Obtained results from this study show that if the AMR and detector system are used together, penal physical exercise of electricity may detected. The system functions with real-time observe users and effect forecast, which uses MV&LV PLC as its transmission media. The system is unified with reason management and shoot down control. infra origin theft, the pass on is switched off isolate the bailiwick of powerfulness theft from the EB side . liquid crystal display display also indicates power theft. zilch regulation does not epresent an obstacle, since PLC service does not affect the power supply and maintains relegate accounts from the core gain business. in one case this proposed system is attempt in real power lines, the distribution losses can be reduced effectively. 15. root 1Hakki Cavd ar, A resultant to remote detecting of illicit electricity usage via power line communication, IEEE Trans. indicant Delivery,vol. 19,no. 4,Oct 2004. 2 T.
