SUBSTATION MONITORING AND CONTROLLING

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.


If the temperature of the substation increases, then the microcontroller will automatically starts the cooling system for the substation. If the voltage ratings of the loads increase beyond the rated values, the system immediately shuts down the substation i.e., the power will be disconnected to the substation from the mains supply.

The controlling continuously monitors the temperature through temperature sensor LM35 and the voltage of the loads through voltage measuring circuit. ADC is used to convert the read analog values into their corresponding digital data. If any of the values exceed its rated values, the controlling unit immediately performs the specified action.
