Substation Monitoring Using Microcontroller and GSM

Abstract

The purpose of this project is to accumulate the remote electrical parameters like voltage, current , temperature and frequency then send these real time readings by GSM network using GSM modem/phone alongside temperature at power station. This project is additionally designed to protect the electrical circuitry by operating a spdt relay. The relay takes action whenever these electrical parameters exceed the predefined readings. The relay is often used to cut the foremost electrical supply. User can receive values of various electrical parameters to their Mobile messages to read the remote electrical parameters. This technique can also automatically send the important time electrical parameters periodically(based on time settings) within the type of SMS. This system is often designed to send SMS alerts whenever the relay trips or whenever the voltage or current exceeds the predefined limits. This project makes use of a microcontroller. The controller can efficiently communicate with the various sensors getting used. The controller is given some internal memory to carry the code. This memory is employed to carry set of assembly instructions to the controller. And the functioning of the controller depends on these assembly instructions. The controller is programmed using embedded c# language.
