Abstract: This paper presents an intelligent, automated load shedding system. This paper stresses on the need to implement intelligent load shedding system as it is advantegous over other existing load shedding system which lack system operating knowledge and are still best-guess methods which typically result an excessive or insufficient load shedding.

The architecture of Intelligent Load Shedding(ILS) system is explained along with a case study. This paper also suggests the use of Thyristor Controlled Breaking Resistor(TCBR) along with Fault Current Limiter(FCL) to enhance transient stability following a major disturbance in power system, the FCL operates for limiting of the fault current, enhancement of the transient stability and suppression of the turbine shaft torsional oscillation and then the TCBR operates with the objectives of fast control of generator disturbances. The effectiveness of both devices has been proved by simulations results.
