Performance of a Fault Location Method in the Context of Modern Electric Power Distribution Systems

Adjustment strategy of a learning‐based faulty zone locator for distribution systems

“…2 Within these approaches, the following classification of methods stands out: (a) those that use measurements through the system and (b) those that require measurements only acquired in the main substation. 3 Furthermore, according to their respective requirements, fault location methods are is classified as: impedance-based locators using single line end measurements, [6][7][8] impedance-based locators using double line end measurements, 9 traveling waves-based locators, 10 learning-based locators, [11][12][13] and location approaches based on the combination of the above strategies. 1,7,8,14,15 The learning-based locators use fault databases composed of voltage and current phasors, obtained during pre-fault and fault steady stages.…”

“…1 In distribution systems, continuity is a complex issue due to the presence of faults, which are the leading causes of supply interruptions, and the unacceptable values of indexes as the system average interruption duration index (SAIDI), system average interruption frequency index (SAIFI). [2][3][4] Fault location is a functionality of the advanced distribution automation, which improves the continuity indexes in three ways. First, speeding up the restoration process; second, enabling the system reconfiguration to reduce the fault affected area; and third, locating areas with non-permanent faults where maintenance is required to avoid future permanent faults.…”
