Advance Substation Monitoring And Protection System

Abstract

This project aims at continuously monitor the load conditions of the substation. It also monitors the temperature of the devices present in the substation. If the load increases beyond the substation’s rated capacity, the microcontroller will automatically shut down the substation and intimates the same to the operator by sending a message through a GSM modem. The GSM modem provides the communication interface. It transports device protocols transparently over the network through a serial interface. A GSM modem is a wireless modem that works with a GSM wireless network. A wireless modem behaves like a dial-up modem. The main difference between them is that a dial-up modem sends and receives data through a fixed telephone line while a wireless modem sends and receives data through radio waves. If the temperature of the substation increases, then the microcontroller will automatically start the cooling system for the substation. AT any point, if the operator wants to know the loads conditions and the temperature, he has to send a predefined message to the modem which is interfaced with the microcontroller and the controller acknowledges the operator with the required information.
