POWER LINE DATA

TRANSMISSION

Why not use electrical lines?

OBJECTIVEable to use the current electricity networks for data transmission purposes

perform the necessary research, demonstration and dissemination for power line communication technology

POWER, BACKBONE OF THE MODERN INDUSTRIALIZED WORLD

Increasing population Growing technology

Putting greater demand on

already strained power

grid system

To increase the no. of

To make existing

grids more

efficient

POWER LINE DATA TRANSMISSION

PLDT : POWER LINE DATA TRANSMISSION

Power line communication (PLC), also called power line carrier, mains communication, power line telecom (PLT), or power line networking (PLN)

using electric power lines to carry information over the power line

signals are carried across already existing power lines, rather than through other mediums such as optical fibers or radio waves

offer new services such as broadband Internet access , power theft detection , Power-on- Demand etc .

PLDT is the art of sending data through power lines

The basic process involves three steps:1. Modulate the data so that it can be sent over the transmission medium.2. Transmit the signal in such a manner to reduce signal distortion.3. Receive and demodulate the signal to extract the data. 

TRANSMITTER RECEIVER

APPLICATIONS OF PLDT

Providing internet services

Providing a check on power theft from

transmission lines

Power on demand

Automatic meter reading

Load control

Transmitting radio programs

In this project we will developed a hardware model to show transfer of digital data on the power line

uses one transmitter circuit and one receiver circuit

In transmitter circuit we use one dtmf generator

the receiver circuit we use dtmf decoder circuit

With the help of dtmf generator circuit we generate different codes at a time

METHODOLOGY

We transfer all the data from the dtmf generator to neutral point in the main line with the help of the high voltage capacitor.

On the receiver hand we receive the same data from the neutral line through the .01 high voltage capacitor and then we use dtmf decoder circuit

in the receiver module we receive a different frequency at a time and we use it as a main controller circuit.

In this project we use main power line as a carrier

We use neutral and earth wire as a data transfer line

FUTURE PLANNING OF THE PROJECT

Gathering more information in context with the various application of power line data transmissionCollecting all the required components for the project hardware modelFormulating a plan of action for the designing of the necessary circuit modelsAssembling of the various components in accordance with the circuit models and thus formulating the projectChecking / testing of the hardware model developedThere by giving it a final shape!
