Abstract

In a deregulated power system, the electric power demand is increasing day to day which may lead to overloads and loss of generation. Transient stability studies place an important role in power systems, which provide information related to the capability of a power system to remain in synchronism during major disturbances resulting from either the loss of generation or transmission facilities, sudden or sustained load changes. The analysis of transient stability is very important to operate the power system more secure and this paper focuses on increasing the transient stability [1] using FACTS devices like TCSC (Thyristor Controlled Series Capacitor), TCPAR (Thyristor Controlled Phase Angle Regulator), SVC (Static Var Compensator). These FACTS devices are optimally placed on transmission system using Sensitivity approach method. The proposed method is to enhance the transient stability on Modified IEEE-14 bus system and IEEE-24 bus system Using Power World Simulator 17 software.
