Transient Stability Enhancement of 110/11kv Substation using ETAP

Transient stability is the ability of a power system to maintain synchronism subjected to large disturbances such as three phase fault, short circuit etc.. Present time power systems are being operated nearer to their stability limits due to economic and environmental reasons. Maintaining a stable and secure operation of a power system is therefore a very important and challenging issue. In this paper power flow and hence transient stability of a multi machine practical power system under northern side of Kerala is investigated. Actual data are collected from K.S.E.B is used for simulation. Also comparison of transient stability with and without SVC is done in this paper.
