Static VAR compensator (SVC) protection practices are presented. Protection schemes comprise a combination of conventional protective relays as well as protection functions performed by the control system. This paper describes different protection functions applicable to SVCs and includes a tabulated overview of possible SVC protection methods. A section is dedicated to testing SVC protection systems. The outlined test procedures may be adopted when commissioning new installations in order to demonstrate proper protection operation. Finally, an important aspect of SVC protective schemes is related to the interactions with transient overvoltages, harmonics, short-circuits, and geomagnetic induced current (GICs) of the transmission network. This paper discusses these issues and identifies areas where careful protection considerations are required.
