OBJECTIVE

The goal of this presentation is to explainworking of our project GSM Based Fault Monitoring System.

It helps to monitor the Power Grid, Industry.We have no need to put a person on relay room to monitor the Fault/ Relay .

This project designs an indication system with overvoltage and over-current.

Components Used

Diodes & Resistors Capacitors LM78XX Regulator LM358 OPAmp Microcontroller Relay Unit LED GSM Modem

LM78XX REGULATORS

Each type employs internal current limiting, thermal shut down and safe operating area protection, making it essentially indestructible.

Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents.

The LM78XX series of three terminal positive regulators.

LM358 OPAmp

The LM358/LM358A consist of two independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range of voltage. 

8051 Microcontroller

The following are some of the capabilities of 8051 Microcontroller-

1. Internal ROM and RAM 2. I/O ports with programmable

pins 3. Timers and counters 4. Serial data communication

Relay Unit

Relay unit has been designed to operate in accordance with the switching signal and controlled quantity.

Following are the points upon which relay has been selected: Operating voltage- Should lie

between 5V – 12V Low loss Instantaneous operation. Compact size Equipped with NO an NC contacts.

GSM MODEM

In this Project GSM Modem is used to develop a Interface between Mobile & Microcontroller by using GSM Sim.

It connects Microcontroller to network provider to send the SMS.

Power Supply for the Circuit

WORKING

We are giving power supply through adapter. Bridge rectifier is used to convert AC into DC. Filter circuit is used to removes the unwanted

repulses and its output is fed at the input terminal of LM78XX series regulator.

The 12V constant Voltage is fed to Relay & 5V is fed to the Modem & Microcontroller.

CONTD…

Microcontroller sends sms “ Industrial fault Monitoring device” when we on the device.

When fault occur relay trips & after some time a SMS will be send to the predefined number about type of fault.

Block Diagram

SCOPE FOR FUTURE ENHANCEMENT

The scope for the future enhancement of the circuit is also shown in the block diagram. If an amplifier connected to the motor or various other equipment at the power grid is connected to the microcontroller circuit and suitable programming is done then along with the fault detection controlling of power grid can also be done by the use of GSM technology.

Features

A message will be sent on the number of Supervisor when the fault occur in the transmission system.

Long life No need to monitor from the Relay room. Negligible electricity consumption Easy to Install No Maintenance Required Very affordable price

ADVANTAGES

No need to monitor from relay room.System can be monitored and controlled from

anywhere.Save time.Save men work.Mobile number can be changed at any time.

Area of Application

The major areas captured by it are : Power Grid Factories Industrial Area Home Automation. And many more…………..

Precautions

All the components must be as per the circuit specification.

Microcontroller & LM78XX should be mounted on the IC base.

Modem tower must be in vertical position for good network.

I. C. should not be heated much while soldering; too much heat can destroy the I.C.

Opposite polarity of Supply can destroy I.C so please check the polarity before switching ON the circuit.

Conclusion & Results

Hence by this project we can Monitor the fault at power grids using GSM Based Mobile by means of SMS.

Grid status will not be lost in power failure condition.
