ABSTRACT
Power line communication (PLC) presents an interesting and economical solution for automatic meter reading (AMR). If an AMR system via PLC is set in a power delivery system, a detection system for illegal electricity usage may be easily added in the existing PLC network. In the detection system, the second digitally energy meter chip is used and the value of energy is stored. The recorded energy is compared with the value at the main kilowatthour meter. In the case of the difference.
INTRODUCTION
The automatic meter reading (AMR) system has become a necessity for most energy suppliers as deregulation, free customer choice and open market competition occur in the energy supply sector. Power line communications has many new service possibilities on the data transferring via power lines without use extra cables. Another important problem may be described as illegal electricity usage for energy suppliers.
Illegal electricity may be a serious problem in many countries. In our country 30%-40% of total electricity consumption is illegal; adding that prevention of its illegal use is of great importance in overcoming this problem. Increasing electricity production and building complexes is not sufficient to meet demand, because of the illegal image of electricity.
DETECTION AND CONTROL SYSTEMS
The proposed control system for the detection of illegal electricity usage is shown in Fig. 1. PLC signaling is only valid over the low voltage-220 VAC power lines. The system should applied to every low-voltage distribution network.
Schematically illustration of detection system of illegal electricity usage.
The system given in Fig. 1 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. If the AMR 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.1,
CONCLUSIONS
A detector system to determine illegal electricity usage via power line communications is designed and proposed. The proposed system is examined in laboratory conditions. Obtained results from this study show that if the AMR and detector system are used together, illegal usage of electricity may be detected. The proposed system has not been tried in real power lines due to nonexistent AMR system in our country. In the near future, combined AMR and detector systems will be tried in our country as explained above. One of the main aims of this study is to start new discussions and propose solutions in this field, because illegal usage is a serious problem in our country. and may also be in other parts of the world.
