Abstract
The problem of small signal instability is usually due to insufficient damping of system oscillations. The use of power system stabilizers to control generator excitation systems is one of the effective methods of enhancing small signal stability of power system. However with change in operating state of the power system, the parameters of PSS require retuning. The power electronic based FACTS controllers are effective for system voltage control and power flow control. They can also be used for damping electromechanical oscillations. This presents a systematic method of developing the mathematical model for small signal stability analysis of power system using FACTS based damping controllers (SVC and TCSC) and the effective location of these FACTS based damping controllers using residue factor method. These FACTS controllers are modeled as current injections in the network. In this, the two axis model of the synchronous machine is used for developing the small signal model of the multi-machine power system with FACTS controllers. Case studies are carried out
