“…Fault-location observability with minimum installation of PMUs in a power system network is an optimization problem that has been solved by different methods such as GA [ 88 ], branch and bound [ 89 ], and tabu search [ 94 ]. The aim here is to utilize synchronized measurements of optimally installed PMUs in a suitable algorithm to locate faults that occur anywhere in the network.…”

This paper presents a comprehensive survey on transmission and distribution fault location algorithms that utilize synchronized measurements. Algorithms based on two-end synchronized measurements and fault location algorithms on three-terminal and multiterminal lines are reviewed. Series capacitors equipped with metal oxide varistors (MOVs), when set on a transmission line, create certain problems for line fault locators and, therefore, fault location on series-compensated lines is discussed. The paper reports the work carried out on adaptive fault location algorithms aiming at achieving better fault location accuracy. Work associated with fault location on power system networks, although limited, is also summarized. Additionally, the nonstandard high-frequency-related fault location techniques based on wavelet transform are discussed. Finally, the paper highlights the area for future research.

“…Reference [14] also makes use of wavelet transform but is different from [13] in a way that this method proposes combined fault locator for three-terminal lines and is based on high and low frequency components of the signals that originate from fault conditions in the system. Fault location on transmission line is first facilitated by optimally placing PMUs to optimize the installation cost but making sure that every bus in the network is observable [15]. Fault location in three-terminal line is also facilitated by wavelet transform and is validated for inclusion of series compensation, mutually coupled line section for various values of fault resistances [16].…”

A fault detection and location algorithm on three-terminal transmission line is proposed. Vast literature on fault location shows that to simplify the analysis, line charging currents are often ignored. To improve the accuracy of fault location, synchronized current and voltage measurements from three ends of the three-terminal line are utilized to detect and locate distance to fault while considering the line charging currents. The method first detects the zone at which the fault has occurred and then locates it from the respective line ends. Since threeterminal lines provide solutions for connecting existing system to the grid, facilitating bulk transfer of power, thus the fault detection and location on the same is important to maintain reliability and security of the system. Performance of the proposed algorithm is tested for various fault types, fault locations, fault resistances and fault inception angles. The 200-kV system is simulated in ATP/EMTP; however, the algorithm is developed in MATLAB. The extensive simulation studies demonstrate accuracy of the proposed scheme.

“…However, the requirement of high sampling rate, uncertainty in the selection of sampling window and problems of discrimination between reflected waves from the fault point and remote end of the line are the shortcomings of this technique. Impedance-based methods can be broadly classified as oneterminal [3][4][5], two-terminal [6][7][8], multi-terminal [9][10][11][12] and wide-area [13][14][15][16][17][18] methods.…”

“…In [13], a two-step scheme which combines a fault-location (FL) algorithm and a fault-side selector is presented. A similar branch and bound and genetic algorithm method is described in [14,15], respectively. An effective strategy for rendering the transmission grid fault observable by optimal deployment of sensors that record global positioning system (GPS)-synchronised voltage measurements is suggested in [16].…”
