objective:
This project aims at continuously monitor the load conditions of the substation.
If the load increases beyond the substation ‘s rated capacity ,the microcontroller automatically shut down the substation nd intimates the same to the operator by sending msg through a gsm modem.
hardware and software tools:
Software tools:
Keil compiler
Orcad
Proload
Hardware tools:
Microcontroller AT89S52
GSM modem
Max232
Cooler
Temperature sensor(LM35)
Gsm modem:
A GSM modem is a specialized type of modem which accepts a SIM card, and operates over a subscription to a mobile
A GSM modem exposes an interface that allows applications such as NowSMS to send and receive messages over the modem interface. operator, just like a mobile phone.
project explanations:
If the temperature of the substation increases,then the microcontroller will automatically start the cooling system for the substation.
Then n/w collects the data from the different feeders of substation and transmission to control monitoring unit.
A predefined msg is send to the modem which is interfaced with the microcontroller and the controller acknowledges the operator with the required information.
Through the (sms)short message service.
