“…Niazy et al discussed the MATLAB implementation of wavelet transform‐based fault location algorithm for rectification of fault. The analysis of circuit status under various climatic conditions was performed by the MATLAB SimPowerSystems toolbox . The requirement from the traditional works for better transmission line was optimization in time, fault rectification, and voltage regulation.…”

Summary Major attributes of an electrical power network are the service continuity and high reliability. The occurrence of fault in the transmission line causes the disruption of attributes. If any fault occurs in the transmission line, the reactive power is generated to compensate the failure. The reactive power compensation is based on the utilization of flexible AC transmission system devices like static synchronous compensator (STATCOM) for power regulation. Many research works investigated the use of flexible AC transmission system in power systems for effective fault identification, classification, and localization. In traditional methods, the influence of fault on network parameters such as consumer gateway communication overhead, memory usage, consumer computational overhead, and critical time was more. This paper introduces a novel framework to identify, classify, and rectify the faults in the power transmission line and reduces the influence level of network parameters. Initially, the proposed algorithm detects the fault and ant colony optimization (ACO) and particle swarm optimization (PSO) are used to optimize the time and rectify the fault by the reactive power injection from static synchronous compensator. Finally, the identified faults are classified using relevance vector machine. The best fitness value by ACO‐PSO assures an effective reactive power generation and fault rectification. The proposed method outperforms the existing models regarding the detection, rectification of fault, and critical time required. The comparative analysis of proposed (ACO‐PSO) method with the existing methods confirms the effectiveness in assurance of high reliability and service continuity.

“…When a fault occurs in the HVDC system, electromagnetic waves will be initiated to propagate along the transmission line following the rules of Bewley's Lattice Diagrams [12]. As soon as the waves arrive at the terminals, they are reflected to travel toward the fault point and will be reflected and refracted again at the fault point.…”

The fault location of VSC-HVDC section for grid integrated offshore wind farm is found by Empirical Mode Decomposition (EMD) using Hilbert transform (HT). The intrinsic mode function (IMF) of the fault generated in traveling wave signal retrieved at rectifier and inverter end is extracted by EMD. The HT is used to detect the magnitude and phase of each IMF. The HT of first IMF (IMF1-H) is evaluated for fault location objective and is further compared with wavelet transform (WT). The efficacy of the proposed fault location scheme is reflected in the simulation result.

“…In order to estimate the fault distance, (1) can be used with the traveling speed of the overhead lines after converting the cable section lengths into corresponding overhead line lengths using a conversion factor k as mentioned in [10], [18]. However, the propagation speed in the lines and cables is not really constant [19] and changes due to atmospheric conditions, insulation temperature and aging. It might be interesting to monitor these constants especially in case of cables.…”

In Nordic Countries, distribution networks are traditionally unearthed and increasingly compensated. For such networks, switching their neutral point to the earth is practically applied through a resistor for better selectivity functions of earth faults. In this paper, the neutral switching and consequently an arrival time of the aerial mode traveling wave reflected from the fault point are utilized to accurately determine the earth fault distance. A concept to create traveling waves is implemented by earthing the neutral via a controlled-thyristor that provides a short period of high fault current and produces traveling waves to estimate the fault distance. Much higher transient signals are generated by earthing through an opposite charged capacitor. A capacitor-resistor divider is utilized to measure the reflected surge over a heterogeneous distribution feeder. An adaptive setting is proposed for stamping the arrival surge. The results provide evidence of the efficacy of the proposed fault distance estimation.
