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.

This article aims to propose a novel single-end protection scheme for the compensated transmission line using traveling waves and game theory. First, this study evaluates the effects of thyristor controlled series capacitor (TCSC) on traveling waves (TW) passing through TCSC location. Following that, it investigates the impacts of TCSC switching on conventional protections based on the traveling wave theory. In the next stage, a single-end method will be presented to protect faults on compensated transmission lines with TCSC. Moreover, the game theory will be employed to discriminate extracted TWs in this article. In total, two techniques (ie, mathematical morphology filter [MMF] and discrete wavelet transform [DWT]) will be used to process the signals and investigate the sensitivity of the proposed scheme regarding the extraction techniques of TW. The proposed protection scheme is revealed to be a reliable and accurate method for all possible types of faults on compensated transmission lines at the middle of the line and with various fault inception angles.
