Supervision and control of substation by using GSM module and microcontroller

Abstract

This paper is concerned with the power quality and efficiency the power system. The system is being complex day by day so there is a need of an automated system to control and supervise the substation. In projected work the substation is modelled with a microcontroller and a GSM module that improves the quality of power transfer and reduces the no. of outages. A platform is used to display the various calculated parameters like voltage, frequency, current, phase angle. All these parameters are sent by a SMS as the system comprises of a GSM module which is interfaced with a microcontroller. The sensors placed at the substation senses the situation and then send related signals to the connected microcontroller. All the mentioned parameters are equated to their pre-defined values in a continuous way to provide protection. Under faulty conditions the unit gets shut down by the employed relays. An alert message can be sent in this situation for indication. Thus, the work is increasing the efficiency of substation in an intelligent manner.
