This paper presents an adaptive distance protection in the presence of Static Synchronous Series Compensator (SSSC), one of the series connected Flexible Alternating Current Transmission System (FACTS) devices.

With the development of FACTS technology, STATCOM is more widely applied in the transmission system and it plays the role of reactive power compensation and making the voltage stability. However, it will inevitably have a negative impact on the relay protection.

Modern energy transmission systems suffer from great voltage dropping due to enormous loads. Therefore, appropriate schemes should be devised to regulate the voltage. FACTS devices such as SVC are often used for this purpose. However, FACTS devised may leads to deteriorate of distance relays operation resulting in inaccurate estimation of faults locations. In this paper the effects of SVC on the distance...
