“…On the contrary, the traveling wave propagating to the left from the fault point f is NDTW, the wave velocity is negative, and M1, M2, ... , Mm are the NDSs whose distances from the DBP are negative. At this time, equations (5) and (6) are still satisfied by all the substations in Figure 3, but the wave velocity is changed from scalar to vector.…”

“…The location of fault points of high-voltage transmission lines is generally realized by the impedance method and injection method. However, the practical application of impedance method is not ideal, because its measurement accuracy is affected by factors such as fault resistance, transformer errors, asymmetry of the line structure, and uneven distribution of zero-sequence parameters along the line [5,6]. Injection method for fault location is more targeted than manual line patrol to find fault points.…”

In order to solve the problem of inaccurate fault location in the transmission network under some abnormal conditions, such as traveling wave location device faults, startup failure and time recording error, a novel traveling wave fault location method based on directed tree model and linear fitting is proposed. A directed tree model of the fault traveling wave transmission along the shortest path is established based on graph theory analysis of traveling wave transmission network. Two straight lines are fitted on the coordinate plane where the accurate fault location is obtained direct by coordinate information of the intersection of these two fitted straight lines (FSLs), according to the transmission characteristics of the fault traveling wave in the directed tree model. The wave velocity is used as the slope of the fitted straight line, and the influence of its uncertainty on the fault location is eliminated. The time record error points of the location device are automatically eliminated in the linear fitting. PSCAD simulation results prove that fault information of the entire transmission network is comprehensively utilized by the proposed method and the ring network is automatically unlooped. The reliability and accuracy of fault location are remarkably improved, particularly for the fault scenarios with recorded information abnormity. INDEX TERMS Transmission network, fault location, traveling wave, directed tree model, linear fitting.

“…In the works in [57]- [59] the fault is detected by determining anomalies in the KF estimated power system signals (amplitudes of currents and/or voltages). Kalman filters have also been used recently in protection applications, references [60]- [62], by the same set of authors, use an EKF approach to estimate the TOAs of TWs.

“…While in [60] the TOA are determined based on singularities of the estimated amplitudes of the power system signals, in [61] the TOA is determined by looking at the residual of the KF states. The work in [62] also uses the residual for determining TOAs but it is meant exclusively to detect lightning strikes, a feature that is reflected in the model used by the KF.…”

As a result of the increase in penetration of inverter-based generation such as wind and solar, the dynamics of the grid are being modified. These modifications may threaten the stability of the power system since the dynamics of these devices are completely different from those of rotating generators. Protection schemes need to evolve with the changes in the grid to successfully deliver their objectives of maintaining safe and reliable grid operations. This paper explores the theory of traveling waves and how they can be used to enable fast protection mechanisms. It surveys a list of signal processing methods to extract information on power system signals following a disturbance. The paper also presents a literature review of traveling wave-based protection methods at the transmission and distribution levels of the grid and for AC and DC configurations. The paper then discusses simulations tools to help design and implement protection schemes. A discussion of the anticipated evolution of protection mechanisms with the challenges facing the grid is also presented.
