This document discusses power line communication (PLC) systems used in smart grids. It begins with an introduction to smart grids and smart buildings. It then defines PLC, discusses its history and applications. The document outlines the basics of PLC, including electromagnetic compatibility issues. It also discusses hardware and software solutions and concludes that PLC is a simple technology that allows networks to be easily set up using existing power infrastructure to optimize power consumption and storage.

7. History of PLC
▸ The PLC technology was introduced for the first time in 1920 (15-500
KHz).
▸ In the 1930s, PLC were used on low and medium voltage networks.
▸ In the 1970s, PLC modem can achieve a bit rate of 20 Kbit /s.
▸ In 1975, the evolution of products enabled two-way communication.
▸ In 2005 the Home-Plug standard come with a rate of 85 Mbit /s.
▸ In 2007 Home-Plug achieve a rate of 200 Mbit/s.
▸ In 2010 IEEE standard come with a rate of 500 Mbit/s.

8. History of PLC
▸ In 2012 global communications protocol (PLC-G3/PRIME) are come Specially
to be used in the Smart Grids.
▸ Currently the data rates ranging from several Mbps to several hundred of
Mbps and it achieve a rate more than 1Gbit/s.

9. Typical applications of PLC
▸ Smart Building
▸ Smart Grid
▸ Street light control.
▸ Transmit of the control instruction.
▸ Automatic Meter Reading.
▸ Signs and Information Display.
▸ Fire and Security Alarm.
▸ Organize energy consumption.

10. PLC basics
▸ The superposition of a low energy information signal to the
power wave.
▸ It operates at three levels :high, medium and low tension.

11. Electromagnetic compatibility
▸ The wiring as an antenna.
▸ Large quantity of energy.
▸ Interference to the existing
users.

▸ Background noise and
narrowband noise do not
have much influence.
▸ The Impulsive noise is
more harmful on the PLC
signal.

14. Conclusion
▸ Simple technology.
▸ Set up of a network is easy, quick and provides an access to data on
any room in the building.
▸ Reduce the power consumption by optimizing the offer with respect to
the demand.
▸ Allow a more adapted use of the storage of electricity.
▸ Can offer a solution because the infrastructure has already been
established.

16. The Frequency Standard For PLC
▸ Low-frequency PLC systems are used primarily to communicate
with remote metering devices about 1KHz.
▸ The lowest frequencies are used for broadcasting (153-279 kHz).
▸ CENELEC-A (3-95 kHz), CENELEC-B (95-125 kHz),
CENELEC-C (125-140 kHz) and CENELEC-D (140-148, 5 kHz).

17. ADVANTAGES OF PLC
17
▸ No separate or new wires are needed to create a network.
▸ Power lines provide the shortest route between the power
stations.
▸ Higher mechanical resistance.
▸ Increased reliability.
▸ Lower attenuation over long distances.
▸ Implementation cost is reduced.
