MICROCONTROLLER BASED PREPAID ENERGY METER



.ppt  Prepaid-Energy-Meter.ppt (Size: 3.51 MB / Downloads: 1480)

INTRODUCTION

The scope of the project work is to introduce advanced technology in converting dc voltage in to ac voltage and introducing prepaid energy metering concept.

The energy meter used in this project work produces pulses according to the load and this meter is converted as prepaid energy meter using smart card, hence this meter can be called smart energy meter.

This kind of smart energy meters also can be installed at each and every house, where the state electricity department going to supply the conventional energy. Now a days energy Measurement and electric energy pilferage detection has become prime importance for the state electricity department.

With the help of this project work lot of Manpower can be reduced and power pilferage can be controlled.

The overall system can be called as AMR (Automatic Meter reading) system, the main advantage of AMR system is that the consumed energy price can be calculated and at the same time price (amount in rupees) can be displayed automatically.

Finally the simplest form of smart metering is a display meter, which allows consumers to monitor consumption in money terms rather than kWh.

DISPLAY

Data code: The data code is located on the left side, the first character of 9 digits. It shows different indication codes, each code represents a kind of data.
Unit: When the displayed data is electric energy, it is kWh.
Data bits: The data content consists of 8 digits character and radix point.
Prompt information and alarm information displayed on LCD.

Function

CPU card is adopted
CPU card is adopted as customer card
And ESAM security module in meter is
Provided to carry out 3DES encryption
Authorization. One meter corresponds to
One card to achieve perfect security.


Electronic meters advantages
High accuracy over a wide current dynamic range
Reliability and robustness
Flexibility of design
Automatic Meter Reading (AMR)
More easily enable new functionalities
Multi tariff billing
Tamper proofing
Prepayment meters
Power out range detection
Power factor detection
Easily reconfiguration, upgrade
Do not use gears that wear out or magnets that saturate with DC current
Do not require precision mechanics or have large tolerance variations over temperature

DISADVANTAGES

The main disadvantage of the system is, because of huge electronic hardware involved in the system, the overall system consumes more electric energy

Remedy: When the system is converted into engineering module, the bulky hardware can be converted into a small-integrated chip. When the hardware is minimized naturally the system consumes less power.

Since it is a prototype module, because of huge hardware the system occupies more space.

The consumer or the electrical department has to spend more amounts for installing this kind of smart energy meters. Economically it is not advised.

CONCLUSIONS

Advanced electricity meters that generate consumption data enabling customers to see when they are using energy, to manage that use more efficiently
To save money by adjusting energy use in response to price signals.
To save money, the consumed energy corresponding price is displayed for the consumer benefits.
This project work has been taken up which serves the purpose of energy monitoring and controlling by implementing prepaid system.
It is hoped that this work helps the electrical engineers for better energy management and its utility in the distribution system for economic liability of the electrical companies.
