PROGRAMABLE ENERGY METER FOR ELECTRICAL LOAD SURVEY

[aayush]

sir ,please guide for programming of microcontroller used in “programmable energy meter for load survey”.and also give me guidness for makig circuit for minor project. please please…………..

Hi Aayush,

Please post all the details regarding the project .

[aayush]

summary:

the project is designed to evaluate consumption of any load in units and cost in rupees as per the energy tariff and the number of hours the load is going to be used. The evaluation is almost instantaneous thus assisting the user to save hours of waiting time for the load survey.

An energy audit is an inspection, survey and analysis of energy consumption with possible conservation in domestic sector or industrial environment etc. As unit cost of electricity is very high these days it is essential to know if a particular device or instrument is energy efficient or not.

This system proposes an energy auditing system for the instruments where the microcontroller calculates the units that will be consumed by the loads and the rupees that will be spent on it. The input data i.e. energy tariff and number of hours the load is likely to be used, is given by the user through push button switches.

The relevant information is displayed on an LCD interfaced with the microcontroller. The microcontroller used in the project is of 8051 family.

sir ,in this project i have to connect digital energy meter to optocoupler for giving digital input to atmega 32. which test the signal ,used for programming to display on lcd.  sir please give help for coding in aurdino and in addition we have have to display number of unit to be used during certain hours,given by push button and also rupee to be paid for this hr which is also to be given by push button.

“This project deals with the calculation of the energy meter billing based on the load consumption given as an input using set up buttons. The microcontroller calculates the rupees that will be consumed by the loads as per the input given and displays it on the 16X2 LCD interfaced with the microcontroller. This project is powered by an on-board power supply takes the ac power and converts it into dc power that is fed to on-board devices and integrated circuits.

The microcontroller used in the project is of 8051 family which is of 8 bit. In the project we use the setup buttons which are used for entering the price of the unit.

The power supply consists of a step down transformer 230/12V, which steps down the voltage to 12V AC. This is c

onverted to DC using a Bridge rectifier. The ripples are removed using a capacitive filter and it is then regulated to +5V using a voltage regulator 7805 which is required for the operation of the microcontroller and other components.”

Hi,

 

For this, there are few meters available which will send you number of pulses on I2C. You require to count it and convert it into units and INR…

[aayush]

please sir expand this,as i’m beginer one , and on 1may i have to submit minor on this topic

 

[aayush]

please guide for coding it.as used atmega32

[SHAH DISHANT H.]

Hi Ayush,

 

Let me explain in brief…!!

 

In my project I had used one energy meter available in market. That meter was giving outout on I2C protocol. To measure

unit consumed by laod, we have to read count value on I2C protocol. 

This meter will have 6 pins..

2 pins for input AC supply

2 pins for LOAD connection

2 pins for I2C..

 

In actual, 30000 gives 1 unit. By knowilng the pulse value, we can know unit consumption…

This is not as easy as we need many things in addition like isolation, snubber protection etc…!!

 

Start working on it and keep posting your problems…!!

[SHAH DISHANT H.]

Hi Aayush,

 

Have you started working on it ?

 

Update please..!!

[aayush]

sir, i complete my minor project on this topic by using magzine “electronic for yu” .having project related details

[SHAH DISHANT H.]

Hi,

 

How you have planned to work ?

 

How much you have done till now ?

 

Keep posting details…!!

 

[maruti ravindra halatti]

Hello Dishant Sir,

 

Give me your Mail ID for further communication related to this project…

 

 

[yy]

Can you just mention the energy metre that you have used sir..??

[athul]

Hello Ayush,

there is a project on EG for Prepaid Energy Meter – engineersgarage.com/contribution/using-arduino-build-prepaid-energy-meters

You can check it out.
