Substation Monitoring System

Abstract

This project is aimed to design a system which can monitor and control the substation by using a wireless technology called IOT . A IOT module provides the communication interface. By using IOT module we can update data on web server. In our project we are considering substation parameters, voltage and current, frequency, temp. The project will be designed in such a way that an sensor will be interfaced to the controller. Here the inputs for the ADC are the analog values of voltage, current . In this project microcontroller is connected to IOT module through serially. By varying these two pots microcontroller detects voltage and current, frequency, temp fluctuations and sends that particular values to the web server. According to voltage and current fluctuations relays has to be triggered for protecting substation at that time bulb will OFF. A 16x2 LCD is also provided to display the status of the system. This project uses regulated 5V, 500mA power supply. Unregulated 12V DC is used for relay. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac output of secondary of 230/12V step down transformer.
