ABSTRACT
ABSTRACT
Electricity usage should be thoroughly monitored in order to find the unauthorized access of the consumers. Electricity theft otherwise termed as non-technical loss has emerged as a serious problem in power Sectors especially in the developing countries. A huge amount of revenue is lost due to electricity theft. Electricity theft includes tampering meters to show a low meter reading, stealing electricity bypassing a meter, billing irregularities and unpaid bills. Different nontechnical and technical methods were proposed in the past to detect electricity pilfering. Nontechnical methods may include inspection of the customers with suspicious load profile. Although periodic inspection can substantially reduce theft, such measure requires large manpower and huge labour. Such effort also fails in most cases due to the dishonesty of the staffs. Meter tampering is another way of stealing electricity. Out of total energy generated only 55% is billed and only 41% is realized.
1.1.1 Methods of illegal electricity usage
· Using the mechanical objects
A subscriber can use some mechanical objects to prevent the revolution of a meter, so that disk speed is reduced and the recorded energy is also reduced.
· Using a fixed magnet
A subscriber can use a fixed magnet to change the electromagnetic field of the current coils. As is well known, the recorded energy is proportional to electromagnetic field.
· Using the external phase before meter terminals
This method gives subscribers free energy without any record.
· Switching the energy cables at the meter connector box
In this way, the current does not pass through the current coil of the meter, so the meter does not record the energy consumption. Although all of the methods explained above
may be valid for electromechanical meters, only the last two methods are valid for digital meters. Therefore, this problem should be solved by electronics and control techniques.
1.1.2 Effects of Electricity Theft
Negative effects of electricity theft are severe and dangerous. Primarily, electricity theft affects the utility company and then its customers. In addition, electricity theft overloads the generation unit. In energy market, utility companies expect their money back from the customers for the electricity supplied, most of which is lost by them due to the shows that they could not invest on measures to reduce the electricity theft. These economic losses affect the utility company’s interest in development of the devices in view of improving the quality of supply or for electrification process. Earlier it was a case that generally takes place in villages because they need more power requirement for their field to drive water pump and for motor. But now days it is not limited in villages but also industrial area as well as consumer side comes under power theft. There are various modes of power theft such as Bogus seal and tampering of seals, Meter tampering, meter tilting, meter interface and meter bypassing, Changing connection etc.

1.1.3 Literature Review
Revenue Assurance and Audit Process (RAAP) is composed of macro-functions to detect and analyze revenues involved in illegal consumption of electricity. Also, Mano R. et al. suggests proper design and implementation of rules in the investigation of illegal consumers. RAAP is targeted at improving the revenues for the utility by reducing commercial losses at about 20% each year. Nagi J. et al. proposed a novel approach of using Genetic Algorithm-Support Vector Machines (GA-SVM) for detecting illegal
consumption of electricity. Load consumption data of all the households is collected, and data mining techniques are used to filter and group these customers before detecting illegal consumption.
2.1 POWER THEFT DETECTION TECHNIQUES.
2.1.1 BY POWER LINE COMMUNICATION (PLC).
PLC signaling is only valid over the low voltage VAC power lines. The system should be applied to every low-voltage distribution network. The system given in Fig. 3 belongs only one distribution transformer network and should be repeated for every distribution network. Although the proposed system can be used uniquely, it is better to use it with automatic meter reading system (AMR). If the AMR system will be used in any network, the host PLC unit and a PLC modem for every subscriber should be contained in this system. In Fig. 3, the host PLC unit and other PLC modems are named PLC1A, PLCNA and are used for AMR. These units provide communication with each other and send the recorded data in kilowatt-hour meters to the PLC unit.
Fig. 3: The proposed control system for the detection of illegal electricity
In order to detect illegal usage of electrical energy, a PLC modem and an energy meter chip for every subscriber are added to an existing AMR system. As given in PLC1B, PLCNB and energy meter chips belong to the detector. The detector PLC s and energy meters must be placed at the connection point between distribution main lines and subscriber’s line. Since this connection point is usually in the air or at underground, it is not suitable for anyone to access, such that its control is easy. The main procedure of the proposed system can be summarized as follows.
The recorded data in kilowatt-hour meters for every subscriber are sent to host PLC modem via PLC modems, which is placed in subscriber’s locations. On the other hand, energy meter chips are located at the connection points and read the energy in kilowatt-hours and also send the data to host PLC unit. This proposed detector system has two recorded energy data in host PLC unit, one, which comes from the AMR-PLC, and the other, which comes from the PLC modem at the connection points. These two recorded energy data are compared in the host PLC; if there is any difference between two readings, an error signal is generated. This means that there is an illegal usage in the network. After that, the subscriber address and error signal are combined and sent to the central control unit. If it is requested, a contactor may be included to the system at subscriber locations to turn off the energy automatically, as in the case of illegal usage.
· Every user has two PLC modems; one is for AMR and the other is used to send the data from second energy meter chip to host PLC modem.
· An energy meter must be installed in the connection box between a home line and main power lines.
· The host PLC modems and its controller must include two addresses per every user: one is the AMR and the other for the energy meter. These two addresses must be selected sequentially.
Advantages
· The developed system is simple and easy to operate.
· It saves time and revenue losses for the utility company.
· It has a better user interface and digital data analysis.
· It is popular due to cost effectiveness and availability.
· Communication over a power line can reach anywhere there is an AC outlet.
Disadvantages
· It has a high level noise and electromagnetic compatibility.
· It has to have high robustness to impulsive noise.
· Initial cost is high.
2.1.2 BY GLOBAL SYSTEM FOR MOBILE COMMUNICATION (GSM)
Meter is installed on load side to measure a power consumed by load over a time. Also it has an additional feature of transmitting that data to receiver using Bluetooth technique.
This meter is capable to measure a power sent over each line connected to that pole. It consists of Wireless data receiver, Micro-controller, Digital energy meter. Digital energy meter will measure power sent over each line for a certain time period.
Digital energy meter (M1) will measure a consumed power by load (L1) over a period. It will send a data in proportion with consumed power to receiver with the help of data transmitter. Receiver on the pole system will receive a data sent by transmitter in a load side meter. Receiver will send it to microcontroller. Also energy meter on pole will measure power sent over line1 and provide appropriate data to microcontroller. Now microcontroller has two readings one is power calculated on pole itself and another is power consumed by load (L1). Suppose there is tapping done by any unauthorized person on the line to connect his appliance as shown in figure1. Over a certain period there will be difference between meter reading (M1) and pole based reading. Microcontroller will compare these two values and if the measured value on pole is more than value send by meter (M1) by some tolerance then power theft is happening on line1. This theft signal generated on pole system can be transmitted to substation by GSM technique. Tolerance should be provided for losses of line. Because over a long period there will be difference in reading of meter on load side and pole side due to loss of line between pole and load. Therefore tolerance should be provided through programming of micro-controller. The GSM module is used to send a sms when electricity theft or any line problem is generated in a transmission line. The microcontroller detects any power theft or fault in transmission line and give the command to GSM module to send a respective massage to substation.
Advantages
· The system consumes very little power for its operation.
· System operation is independent of time (24 hours functioning).
· Automatic user identification.
· Low cost and low power consumption.
· Data collection and manipulation task becomes easier.
· Unit calculation can be done effectively.
· It displaying information in long distance and the information can be send after according to user requirements.
· Automatic user identification.
Disadvantages
· Cannot determine who is stealing but even no other existing system is capable of doing this.
· If implemented on a large scale it may take lot of time and manual input.
· Wide range of frequencies are required to facilitate large number of users
2.1.3 BY Zigbee NETWORK
It is more effective as compared with other methods because of its effective communication, self-healing networks, low power consumption, zero traffic and they can handle over 60000 devices and more over Zigbee communication installation require no special permissions in most of the places. It uses unlicensed 2.4 GHz ISM band which is available worldwide. ZIGBEE has range between 10 m to 2 km and it works well with networks such as Wi-Fi, Ethernet and GPRS and also provides scalable networking solution which makes it suitable to be used in controlling and monitoring application. And we selected other communication network to be GSM to send SMS to authorities in case of theft, because GSM has a built in transport layer encryption, which is supported by most network providers.
It consists of Load, current transformer, voltage transformer, PIC micro controller, and a differential relay. The household load supplied is connected in series to the AC supply mains through a switch which is operated by the action of a relay. Current transformer is used to measure the current required for the user and the voltage transformer is used to measure the voltage of operation for the user. The measured values are given to the PIC micro controller which has inbuilt ADC with RISC architecture to convert the analog values to the digital values. These values are stored in microcontroller registers and the information is transmitted to the receiver, whenever there is a request for the data from the remote controlling station. Oscillator is provided to the microcontroller for the clock signal and the reference voltage is given for the each of the IC used.
The receiver part consists of an ARM micro controller, Zigbee receiver, LCD display and alarm to pop out theft case, and also an external GSM modem to inform theft case to authorities via SMS.
Advantages
· 2.4 Ghz, 915 MHz and 868 MHz (license-free ISM band).
· It may gives a big hand to vigilance squad to control theft quickly.
· Extent of theft can be identified.
· Errorless tariff calculation and low power consumption.
· Efficient meter reading, power monitoring and control.
· It has more stable network with robust features covers virtually all part of world and low price.
Disadvantages
· A maintenance staff of highly skilled and high trained personnel are needed.
· High maintenance cost.
2.1.4 AUTOMATIC METER READING (AMR):
Automatic meter reading, or AMR, is the technology of automatically collecting consumption, diagnostic, and status data from water meter or energy metering devices (gas, electric) and transferring that data to a central database for billing, troubleshooting, and analyzing. This technology mainly saves utility providers the expense of periodic trips to each physical location to read a meter. Another advantage is that billing can be based on near real-time consumption rather than on estimates based on past or predicted consumption. This timely information coupled with analysis can help both utility providers and customers better control the use and production of electric energy, gas usage, or water consumption. AMR technologies include handheld, mobile and network technologies based on telephony platforms (wired and wireless), radio frequency (RF), or power line transmission. The AMR system starts at the meter. Some means of translating readings from rotating meter dials, or cyclometer style meter dials, into digital form is necessary in order to send digital metering data from the customer site to a central point. In most cases, the meter that is used in an AMR system is the same ordinary meter used for manual reading but the difference with conventional energy meter is the addition of some device to generate pulses relating to the amount of consumption monitored, or generates an electronic, digital code that translates to the actual reading on the meter dials. One such technique using optical sensor is shown in below .
Important Components Of AMR System Are:
· Meter interface module: with power supply, meter sensors, controlling electronics and a communication interface that allows data to be transmitted from this remote device to a central location. In many instances, this communication interface is bi-directional and allows central office signals to be received by the remote unit as well. Every electric, gas or water meter must have such an interface unit to be remotely read. Some key components of the remote device may be shared by more than one meter without regard for the type of meter; i.e.., electric gas or water
· Communications systems: used for the transmission, or telemetry, of data and control send signals between the meter interface units and the central office.
3.1 APPLICATIONS
· For digital data transmission.
· Can be use for data logger to make it wireless.
· For parameter transmission/monitoring.
· High initial cost.
3.2 ADVANTAGES
· Continuous remote monitoring: - monitoring of the transmission line in the remote areas can be done continuously 24 hours.
· System health detection :- At receiver side LED‟s blink which indicate proper transmission between transmission and receiver side
· Our circuit is totally noise free.
· Components are easily available.
· Low power consumption
· One time investment
· It will save money of employees those are taking door to door reading.
· It is not possible to interrupt wireless data
· Easy to implement
· Flexible system
3.3 LIMITATIONS
· We cannot detect actual amount of power because we are differentiating current.
· In case of power failure, system fails .this disadvantage can be overcome by using UPS or backup power.
· It cannot be used for variable load.
CONCLUSION
By this design would like to conclude that the power theft can be effectively curbed by detecting where the power theft occurs inform the authorities. Thus by the above mentioned design we can successfully and effectively address the problems related to power theft by the consumers, in a completely automated, cost effective and most importantly a reliable way. GSM wireless theft monitoring system can use long-range wireless communication and computer network technologies to send SMS. By this system it can be concluded that power theft can be effectively curbed by detecting where the power theft occurs and informing the authorities. These techniques help to saves time as well as help to maximize profit margin for utility company working in electrical distribution network. Utility company can keep a constant eye on its customer. The SMS system used sends an SMS to the server station immediately if some pilferage occurs. So, legal actions can be taken against the consumers who are resorting to electricity thefts with the help of SMS. Once this proposed detection systems are tried in real power lines, the distribution losses in India can be reduced effectively.
