Performance analysis of controllable facts devices on power network

Abstract

This paper presents a detailed performance analysis of power system oscillations damping capabilities of controllable FA CTS devices under different line loading conditions and reactive power requirements of the system. The system studies are carried out based on the model developed in state space frame work. The model developed is modular and any degree of details of system can be included. The effectiveness of FACTS controllers, such as, controllable series compensation (CSC), thyristor controlled phase shifter (TCPS) and static var compensator (SVC) under varying load has thoroughly been evaluated. It has been demonstrated through sim ulation that each controller has special contribution towards oscillation damping based on the location. The observations on the controllable FACT devices have been made based on the adequate control generated and the stability enhancement capabilities.
