“…On the other hand, [14] and [15] show correct performance for internal fault owing to high sampling frequency and non‐degradation of high frequency TWs with STATCOM production harmonics; however, they face challenges when identifying external forward fault. In contrast, the double‐end algorithms proposed by [10] and [11] performed correctly. It is worth mentioning that these studies proposed no algorithm for external fault detection.…”

This study aims at proposing an original single‐end protection scheme for the compensated transmission line using traveling waves and game theory. To this end, this paper initially investigates the effects of static synchronous compensator (STATCOM) on traveling waves passing through STATCOM installation point. Furthermore, based on the traveling wave theory, it evaluates the impacts of STATCOM's harmonic on conventional protections. A single‐end method will be proposed in the next stage for fault protection on the compensated transmission lines with STATCOM. The extracted traveling waves in this study will be discriminated using the game theory, and discrete wavelet transform will be utilized to process the signals and assess the sensitivity of the proposed scheme considering the extraction techniques of the traveling wave. According to the obtained results, the proposed protection scheme is a reliable and accurate method for all possible faults type on compensated transmission lines at the various locations of the line and with different fault inception angles.

“…Ref. [10] proposes a fault detection algorithm using the discrete wavelet transform (DWT) and the synchronized current samples at both ends of a compensated TL with STATCOM. The fault index is estimated utilizing the sum of the local and remote end detail coefficients.…”

“…Effect of fault resistance and operating mode of FACTS controller on the performance of wavelet based relay is not investigated. Detection and classification of transmission line faults in the presence of STATCOM using wavelet based summation index is discussed in [18]. However, effect of fault resistance and change in operating mode of STATCOM on the relay performance is not investigated.…”

This paper proposes a new wavelet transform based relay logic for the protection of transmission lines compensated with a static synchronous compensator incorporating energy storage device (STATCOM -ES). STATCOM with energy storage systems can operate in any of the four quadrants in P -Q plane. A conventional distance relay with standard settings may not be reliable to identify and categorize short circuit faults in such systems. A simple, fast acting and reliable wavelet based relay logic is presented to accurately identify and categorize transmission line faults in shunt compensated lines. The developed relay discriminates between internal and external faults accurately. It provides reliable protection for the transmission line considering the entire four quadrant operating range of STATCOM -ES and is immune to the value of fault resistance.
