Flexible AC Transmission and a study of Static Voltage Compensator

Abstract

Development of electrical power transmission systems follows closely the increasing demand on electrical energy. With the increasing size and complexity of the transmission networks, the performance of the power systems decreases due to problems related to with load flow, power oscillations and voltage quality. Flexible ac transmission systems (FACTS) and High-voltage direct current (HVDC) technologies offer some effective schemes to meet these demands. In recent years, FACTS technology has been considered as one feasible planning alternative in India to increase power grid delivery capability and remove identified network bottlenecks. An attempt is made in this paper to discuss the development of FACTS, types of FACTS and simulation of VSC, using SIMULINK is carried out for comparing voltage regulation issues, total harmonic distortion (THD) with varying transmission line distances.
