“…In Ref. (Barati and Doroudi 2018), the authors modified the impedance-based method for estimating the distance of fault in transmission lines in the presence of the fault current limiting. On the other hand, the travelling-based fault location methods have been proposed for estimating the fault location in the distribution network, such as the unsynchronized-and synchronized-based methods (Kalita et al 2021;Chafi et al 2021;Han et al 2020), the adaptive convolution neural network-based method (Liang et al 2020), and the single-end travelling wave fault location method (Xu et al 2014).…”

“…The signal processing methods depending on the selected fault location method are applied to obtain data, extract the significant features, and determine the fault location. In this stage, several signal processing methods, consisting of the modal analysis and the wavelet transform, are used for the travelling wave-based method (Mosavi et al 2016;Reis et al 2021;Sawai et al 2020;Fedorov et al 2020), and the time domain and the frequency domain methods are applied to the impedance-based method (Han et al 2020;Takagi et al 1982;Namas and Džafić 2020;Barati and Doroudi 2018;Khoa and Tung 2018). The outputs of the signal process are considered as the inputs of the executed analytics to calculate the fault distance.…”

Power transmission system stability can be significantly affected due to faults. The fault location accuracy in the transmission lines can make many benefits such as acceleration of the line restoration, reduction in cost, breakdown time, maintenance, and time searching. The methods based on the impedance, including the simple reactance, Takagi, modified Takagi, and double-end, are very much appreciated for locating the fault in transmission lines and especially by estimating the fault distance. This study proposes a comparative case study between these methods. The theoretical basis and the analysis, calculation, and estimation of each method are specifically re-established. To observe the performance of each method, a practical 220kV Quy Nhon - Tuy Hoa transmission line in Vietnam is used to simulate, calculate, evaluate, and compare under the various fault types and resistances. The power system is modeled and simulated in the MATLAB/Simulink software via the time domain. The voltage and current measurements at two ends of the line are used to determine the fault location on the Quy Nhon - Tuy Hoa transmission line. The simulation results show clearly the effectiveness of each fault location method.

The transmission network has been considered among the globe's prevalent complex systems, comprised of hundreds of electrical transmission lines and other equipment used to transmit electrical energy from one location to another. Over a decade, power engineers have worked tirelessly to ensure that the transmission network operates reliably, transmitting electrical energy from the power station to the consumers without interruption. With growing generation capacity and the recent introduction of renewable energy systems (RES) such as wind turbines and solar energy, the transmission lines are increasingly being forced to run near their design limitations and greater unpredictability on the network operational configuration. As a result, the transmission network faces greater challenges than previously. As a worst-case scenario, large-scale electrical network power outages caused by electrical faults can disrupt electricity availability for several hours, impacting millions of customers and inflicting massive economic damage. These electrical faults must be repaired before electricity is restored to consumers. This necessitates a thorough grasp of the challenge and potential remedies to assure improved power efficiency. In the present work, an expansion of preceding work, a novel algorithm for estimating faults on transmission lines is presented. Impedance-based techniques are susceptible to producing errors or incorrect predictions. The presence of faults induced from high impedance sources produces an extra impedance to the ground, which negates the impedance calculation and produces errors in the distance to the fault. This results in inaccuracies that can affect a distance-to-fault estimation by 1-15 % of the overall line length. In this work, a design of a fault detection-location element (FDLE) algorithm is proposed. This algorithm relies on the dynamics of current and voltage signals on the transmission line while deserting impedance. Comparison research is undertaken against the impedancebased techniques to validate the proposed algorithm. Finally, the proposed algorithm findings are compared to fault location estimations using an impedance-based technique. Extensive trials on a simulated transmission line prove that the proposed algorithm is responsive to faults with an error as low as 1%, reaching a precision of 98.9%.

The fault location problem is one of the most important issues in power system operation and control. To obtain an experimental system for teaching and training electrical engineering students, this paper performed a study to design and implement a real-time fault location laboratory-scale model from practical hardware components. The impedance-based fault location method is embedded in the system to determine the distance to fault in the transmission line. Furthermore, the monitoring and controlling program is designed by the Matlab App Designer – A new professional app to create the graphical user interface and use the integrated editor quickly. Several fault types including three-phase fault, phase-to-phase fault, phase-to-ground fault are created to evaluate the performance of the fault location experimental system. The real-time measurement results which are acquired and observed on the user guide interface of the program confirm the effectiveness of the experimental system; therefore, the system can be considered a powerful tool for electrical engineering students.
