INTRODUCTION The main objective of the project is to develop a bi-

directional pre-paid energy meter which is based on the tariff plans.

The application is mainly based on microcontroller.

The microcontroller takes the reading from the energy meter and displays the reading on the LCD screen.

There will be improvements in traditional billing systems. 

CURRENT SCENARIO It’s a post-paid system.

The meter reader used to come to take reading.

The load demand fluctuates a lot in a day.

Very few users pay the electric bill on time.

Currently minimum charges are more than it should be.

COMPONENT USED IN THIS PROJECT

Energy meter 2 Microcontrollers(Aurdino) Different source of power supply Real time clock (Ds3231) Relay (DPDT) GSM module with working SIM and

PROBLEM IN DESIGNING THE ENERGY METER

To take reading from energy meter.

To Calculate the remaining balance.

To distinguish between the units sold and purchased.

To apply the charge of units as per tariff scheme.

To communicate to retailer and consumer.

To verify that the message is received from authorized retailer or someone else.

To detect that the message is for recharge or anything else and for how many rupees of recharge.

To decide that the message is to be send to retailer or consumer.

To make a bi directional meter.

To make communication with real time clock.

ADVANTAGES Due to tariff scheme the load will not

fluctuate too much in a day.

The losses will reduce due to moderate demand.

The person who doesn’t use the electricity can sell their electricity.

SCENARIO AFTER THISMODIFICATION

Meter reader will not have to come to take meter reading.

Everyone has to pay before they use.

We use tariff base scheme which can moderate the load demand.

Everyone has to pay the fix cost whether they are using the electricity or not.

FUTURE SCOPE This project have a versatile scope in

future.

For making a smart grid it is very useful.

Will promote the non-conventional energy sources.

Will promote the full utilization of electrical energy.
