“…Reference [53] extends this approach to a simple line with several sections, and [54,55] extend it to multi-section non-homogeneous lines. Additionally, an alternative approach is proposed by Jiang [56], which studies all nodes comparing them with a normal situation, identifying the affected section with this difference.…”

Abstract:In the last few decades, the Smart Grid paradigm presence has increased within power systems. These new kinds of networks demand new Operations and Planning approaches, following improvements in the quality of service. In this sense, the role of the Distribution Management System, through its Outage Management System, is essential to guarantee the network reliability. This system is responsible for minimizing the consequences arising from a fault event (or network failure). Obviously, knowing where the fault appears is critical for a good reaction of this system. Therefore, several fault location techniques have been proposed. However, most of them provide individual results, associated with specific testbeds, which make the comparison between them difficult. Due to this, a review of fault location methods has been done in this paper, analyzing them for their use on underground distribution lines. Specifically, this study is focused on an impedance-based method because their requirements are in line with the typical instrumentation deployed in distribution networks. This work is completed with an exhaustive analysis of these methods over a PSCAD TM X4 implementation of the standard IEEE Node Test Feeder, which truly allows us to consistently compare the results of these location methods and to determine the advantages and drawbacks of each of them.

“…These methods only need a voltage and current measurement (typically registered at line header). Conversely, two-end (or multi-end) methods [52][53][54][55][56][57][58] use measurements at several nodes, analyzing the differences or imbalances between them, and using this information in order to locate the fault.…”

“…The classical fault location algorithms were proposed in the 1980s [8][9][10]. After that, there appeared many fault location algorithms [11][12][13][14][15][16][17][18][19][20][21][22][23]. Transmission line fault location techniques can be mainly divided into three categories [11][12][13]: single-ended data method [8][9][10], dual-ended data method [13][14][15][16][17][18][19] and traveling wave method [6,7] [20][21][22][23].…”

This paper presents a new fault location technique based on the fundamental frequency positive sequence fault components, featuring robustness to the operating state of the prefault system and fault path resistance. Using the fundamental frequency positive sequence fault components, the technique described in this paper does not require the user to know the fault phases and fault type in advance or use a line zero sequence parameter, which is not only difficult to obtain but is also affected by soil resistivity and thus may be variable. In addition, based on the fault components protection principle, the method is inherently unaffected by the operating state of the prefault system. Accurate transmission lines' fault location is important for expediting their repair or reducing outage times, so the proposed technique could improve the quality and security of the electricity supply. This paper describes the characteristics of the proposed technique and assesses its performance by using the PSCAD/EMTDC simulation. © 2020 Institute of Electrical Engineers of Japan.

“…This means that an LVDC distribution system requires a rapid and precise protection scheme because it includes many sensitive components such as converters and digital loads. Specifically, the rapid identification of the fault section or location is directly related to the reliability of an LVDC distribution system [5,6].…”

The increasing importance of energy efficiency has led to several studies related to the construction of a reliable low voltage DC (LVDC) distribution system. Specifically, studies on a protection scheme that considers the fault characteristics of an LVDC distribution system are essential to improve system reliability. When compared to a conventional distribution system, the most distinct feature of an LVDC distribution system is the existence of a capacitive discharge current from converters under a fault condition that results in the prompt operation of protection devices. Therefore, this study involves proposing a precise and rapid technique to identify the fault section in an LVDC distribution system. The technique involves two stages, namely: an analysis stage to analyze the capacitive discharge current and a decision stage to identify the fault section based on the fault type. A detailed discussion of each step is presented and its feasibility is verified based on the results of simulations with an ElectroMagnetic Transients Program and MATLAB Ò .
