“…They can be further subdivided into methods that use GPS synchronised measurements or non-synchronised measurements. These methods are, in general, more accurate than single-ended methods as the influence of fault impedance and mutually coupled circuits is mitigated [5,6]. The algorithms are also characterised on the basis of the model they use: sequence model or phase-based asymmetric model.…”

Accurate fault locating minimises labour and outage time. Efforts to increase the accuracy of fault locating methods are ongoing. In this study, a dynamic state estimation-based fault locating (EBFL) method is proposed. Best implementation requires GPS synchronised sample value measurements at both ends of the line. The dynamic state estimator operates on the sampled values using a detailed dynamic model of the line, which includes the fault location as a state. Specifically, the dynamic line model is represented as a multi-section transmission line model, inclusive of phase conductor type and size, shield wire(s) type and size, and tower ground impedances, integrated with the fault model. This study presents extensive numerical experiments demonstrating that the method has higher accuracy than traditional fault locating methods for different fault types, locations and impedances. Additionally, the method works for both two-terminal and three-terminal transmission lines.

“…In order to improve the main algorithm accuracy and reduce errors in fault location, some modified algorithms have been provided [15]. In [16–18], fault location algorithms for two circuit lines have been presented, which utilise both faulted and sound lines data. In [19], by using the network impedance matrix, the impedance of the equivalent sources of two line ends is estimated.…”
