Design and Development of an Efficient Prepaid Smart Energy Meter

Project Title

Design and Development of an Efficient Prepaid Smart Energy Meter

Project Area of Specialization Augmented and Virtual RealityProject Summary

Prepaid energy meter is a concept in the measurement of electricity consumption on periodic
basis. For the efficient energy management the distribution system has been improved day by
day but the energy measurement and billing system does not improving in the present day which
leads to lot of power theft cases.  Most of the developing countries are moving into smart meters equipped with
prepayment facility to measure electricity in order to reduce the financial losses faced by utilities
due to consumer reluctance to make bill payments on time. Prepaid smart meters enable
consumers to effectively manage their electricity usage. This work deals with designing and
implementing a digital prepaid energy meter which is affordable for domestic consumers. This
meter also shows the peak hours to the user. Also, it gives the overvoltage protection to the
consumer. And it also sends information seal breaking of meter to the utilities.

Our project is to Design and Development of an Efficient Prepaid Smart Energy meters  for the improvement in billing system and theft in power sector.Lots of different feature are included

Difference in our projects are mention below .

• Seal breaking information to utilities 
• Bypass meter protection 
• Tempeating protection
• overvoltage protection to the consumer
• Computing and displaying active and reactive power in real time
•  Displaying peak hours and their intimation to the users
•  Calculating amount to be paid and displaying it on user’s demand
•  Restricting the user to operate under his/her sanctioned load
• Comparison of developed meter with the meters that are available in the market
• Money and time-based load connection and disconnection.
• Only operated on demanded load.

Project Objectives

our objective is to Design a efficient prepaid Energy meter for the improvement in billing sector, as lots of printing and  labour is spending for the collection of bills.lots of error are occured so this is the best solution for the fast and acurate  tool for billing. lots of benifits are available for both utilities and consumer.

• Reduce the unnecessary wastage of power.
• No Need to stand in queue for the payment of bill.
• No surprising bills, No dispute.
• Reduce financial Risk.
• Better customer service.
• Tempering and fraud detection.

Project Implementation Method

The primary focus is to design a prepaid digital energy meter using GSM. For the Designing of energy meter, we use the microcontroller, energy IC, Current sensor and
also the voltage sensor. Also design a power supply for microcontroller of 5V. RTC is used to counts the seconds, minutes, hours, date, months and years.

The task is to design and develop a prepaid smart energy meter that performs the following
tasks:

•  Computing and displaying active and reactive power in real time
•  Displaying peak hours and their intimation to the users
•  Calculating amount to be paid and displaying it on user’s demand
• Over voltage protection to  consumer

The method used to make the project prepaid is the principle of serial communication in collaboration with embedded system. The project has an electric meter which will work
with a GSM modem which is the latest technology used for communication between   modem and embedded systems. The modem will send a message when desired to the
electricity officials through the Subscriber Identity Module (SIM) inserted inside the modem.

Benefits of the Project

Outcomes and applications

• Domestic level and commercial level.
• Used for Improvement of billing process.
• Reduce the unnecessary wastage of power.

Advantages to consumer  

• No Need to stand in queue for the payment of bill.
• No surprising bills, No dispute.
• Help the consumer to contribute towards energy conservation.

Advantages to Utilities 

• Reduce financial Risk.
• Better customer service.
• Tempering and fraud detection.
• No billing hassles 
• Load/demand control.
• Money and time-based load connection and disconnection.

Technical Details of Final Deliverable

• overvoltage protection 
• seal breaking information  to consumer 
• Computing and displaying active and reactive power in real time
• Displaying peak hours and their intimation to the users Calculating amount to be paid and displaying it on user’s demand
• Only operated on demanded load.
• Peak hour displays off peak, on peak, Mid peak hours;
• Prepaid smart meters enable consumers to effectively manage their electricity usage.
