“…When pressing the button OFF above the circuit breaker CB2, the program will initialize the Modbus communication with the IP address of the CB2: 192.168.168. 16. The program will then perform the commands to write the value 1 on the coils 1 and 6, other coils will be written by the value 0.…”

“…[14], the impedance-based method was modified for estimating the distance to the 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 [15][16][17][18][19], the adaptive convolution neural network-based method [20,21], and the single-end traveling wave fault location method [17,22,23]. For hybrid distribution lines, the authors in [24] proposed the single-ended fault location method based on the characteristic distribution of traveling wave along the transmission line.…”

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.

“…There are two main types of FLMs proposed in the literature. First, the ones which study the fundamental component of voltages and currents are known as impedance‐based methods [3, 4, 5]. They are said to be cost‐efficient but face the problem of multiple location estimation on radial grids with a single‐end measurement [6, 7].…”

This paper extends the study of a zero‐sequence impedance‐based fault location method (FLM) designed for medium voltage (MV) distribution feeders whose principle has been presented in a previous work Bach et al. This method is able to locate any type of earth fault with any type of neutral grounding inside a convex set of nodes forming the solution area. The total length of the lines inside this area is statistically computable a priori and depends only on the number and location of additional voltage measurements deployed on some remote end secondary substations. To be efficiently applied to the most challenging rural feeders presenting a lot of ramifications, simulations have shown a need for synchronized measurements, such as the ones obtained using phasor measurement units. Besides, this paper addresses the coupling potential of this method with more traditional ones such as Takagi‐based FLMs to enhance the performances of both, solving the multiple estimation problem while potentially locating the fault within one node. Finally, an extensive sensitivity analysis has been carried out, showing a good robustness with respect to impedance estimation errors or fault impedance values while showing the need for synchronization, especially on some remote measurement locations.

“…Recentemente, a publicação de Apostolopoulos et al (2022) apresentou dois algoritmos de localização de faltas desenvolvidos a partir de dois pontos de medição. De acordo com os autores, os locais de medição devem ser escolhidos, preferencialmente, na subestação e numa barra terminal com GD.…”

“…Então, o método dos mínimos quadrados é usado para estimar a distância da falta. (APOSTOLOPOULOS et al, 2022) A localização das faltas é conduzida a partir da escolha entre dois algoritmos de localização, considerando a matriz de impedância com cargas. Basicamente, esses algoritmos fazem uma busca da seção faltosa resolvendo, por meio de métodos numéricos iterativos, equações do local da falta específicas para cada tipo de falta.…”
