摘要

In this paper, an advanced scheme of fast discrete Stransform (FDST) based compensated line is proposed. This scheme is proposed for the detection and classification of the single circuit transmission line with reference to Unified power Flow controller (UPFC) Position, which is centrally located in the transmission line. The scheme starts processing by extracting each phase currents signals (A or B or C-phase) from both end (i.e, sending and receiving end) of the transmission line synchronously. It processes through FDST to derive the spectral energy (SE) of current signals. The Differential Spectral Energy (DSE) of current signals (i.e, spectral energy of current measured at sending end minus spectral energy of current measured at receiving end) of respective phases of transmission lines is used to register the fault pattern.
