“…Moreover, a load flow is required to estimate the voltages and current at the faulted section in order to estimate the exact fault distance. Three phase currents and voltages from all terminals were measured and synchronized in [9]. The authors suggested a technique which reduces the multi-terminal line to a two terminal line based on the voltage differential between the terminals [9].…”

Abstract-Multi-tapped lines are common in integrated power systems and microgrids which supply variable loads between the main source and the main load. Adopting a cost effective and efficient method for fault location is important for fast power recovery and improving system reliability. A method requiring measurements only at the ends of the main distribution line is proposed in this paper to solve the issue of locating faults on the tapped lines as well as on the main line without any measurement required from the taps. A combination of singleended and double-ended algorithms based on higher frequency impedance estimation are utilized to locate the faults within the tapped line. The study considers different fault types in different locations as well as various fault inception angles. The presented results shows the efficiency and the accuracy of the suggested technique with maximum error less than 3% of the total line length.Index Terms-Fault location, impedance estimation, integrated power systems, protection and tapped lines.

“…Different fault analysis methods have been proposed in the literature either as a separate fault detection, classification, and location functions or as a complete fault analysis tool [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. A group of methods are developed, considering line impedance calculation [8][9][10][11][12][13][14][15][16][17], while several others are based on high-frequency transients, traveling waves, and wavelet-based methods [18][19][20][21].…”

a b s t r a c tIn this paper, a real-time tool to detect transmission line relay mis-operation is implemented. The tool uses time-synchronized measurements obtained from both ends of the line during disturbances. The proposed fault analysis tool comes into the picture only after the protective device has operated and tripped the line. The proposed methodology is able not only to detect, classify, and locate transmission line faults, but also to accurately confirm whether the line was tripped due to a mis-operation of protective relays. The analysis report includes either detailed description of the fault type and location or detection of relay mis-operation. As such, it can be a source of very useful information to support the system restoration. The focus of the paper is on the implementation requirements that allow practical application of the methodology, which is illustrated using the field data obtained the real power system. Testing and validation is done using the field data recorded by digital fault recorders and protective relays. The test data included several hundreds of event records corresponding to both relay mis-operations and actual faults. The discussion of results addresses various challenges encountered during the implementation and validation of the presented methodology.
