Technical comparison of FACTS controllers in parallel connection

Esther Barrios-Martínez, Cesar Ángeles-Camacho

Abstract


The Static VAR Compensator (SVC) and Static Synchronous Compensator (STATCOM) have the ability to provide dynamic compensation to a transmission system. Their speed of response enable increased transient stability margins, voltage support enhancement, and damping of low frequency oscillations. The main operational objective of both FACTS devices is to increase power transmission capability by voltage control at the point of connection of the power network. In this research both controllers are compared by their most important features, such as the following: the performance VI and VQ curves, the response time, the physical size, the cost and behavior in steady-state and transient stability. Results show a small advantage of the STATCOM.
