In large inter connected power systems, inter-area oscillations are turned to be a severe problem. Hence inter-area oscillations cause severe problems like damage to generators, reduce the power transfer capability of transmission lines, increase wear and tear on network components, increase line losses etc. This paper is to maintain the stability of system by damping inter-area oscillations.

The aim of this paper is to propose works by analysing, the data sent from the admin through Wi-Fi and provides acknowledgement to the admin through the same system used for communication. The reason why Wi-Fi has been ,used for broad-casting the data is that today’s conventional educational institutions have Wi-Fi facility in their campus for providing internet connectivity to the students. Broad-casting is done by sending the data to all the access points by accessing the broadcast ID of the network in which this system is to be implemented. Hence the same Wi-Fi system can be used to broadcast the message from administrator to classrooms and vice-versa.
