Analysis of Voltage And loss Profile Using Various FACTS Devices

摘要

The Aim of this paper is the study of models and procedures with which we assess the steady-state operation of electrical power systems at the fundamental frequency. The improvement of stability will be achieved by controlling the reactive power flow in the line[3]. The Flexible Alternating Current Transmission System (FACTS) devices have been proposed to control the power flow in transmission lines & to regulate the bus voltages in electrical power systems resulting in an increased power transfer capability, less system losses and improved stability[8]. This summary presents the implication of adding various FACTS controllers such as a Static Var Compensator SVC, TCSC (thyristor controlled series capacitor) and UPFC (Unified power flow controller) etc. So a power flow program using MATLAB finds the steady voltage and angle at each bus and corresponding for a given system and finds the load ability margin of power system with FACTS devices. A 2 machine 5 bus system is considered for performance analysis[9]. This paper states the implementation of FACTS in a Newton raphson load flow (NRLF) method.
