“…However, large mathematical computations involved with this technique results large computational burden. Further, during high resistance fault the response of FDST is challenging. Hilbert Huang transform (HHT) based method [23]: Further, HHT based technique has been proposed which computes the DTEO of the both ends current signal in order to achieve the secure and reliable differential protection. This method is advantageous as compared to aforementioned techniques, however, performance of this method has not been tested for various non‐fault scenarios.…”

Conventional transmission line protection algorithms may experience delay or even maloperation in presence of shunt compensation due to various non-fault transient disturbances. This paper presents a time-domain differential protection technique based on Kullback-Leibler divergence with thresholding logic for mid-point static synchronous compensator compensated transmission system. A detection index for each phase currents are computed in order to discrimination the fault and non-fault scenarios. Different structure of power systems modelled using EMTDC/PSCAD are simulated to generate numerous numbers of test cases in order to evaluate the applicability of the proposed differential protection logic. Proposed method is also efficient to differentiate the faults during various non-fault events like capacitor switching, sudden load change, power swing, and current transformer saturation including external fault cases. Results and comparative assessment with recently proposed time-frequency and commercial current differential relaying reports demonstrate the efficacy and robustness of the proposed technique. The results confirmed the accurate operation of the proposed protection technique.

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.

“…It is possible to apply classical or innovative algorithms for these purposes [23,24]. When the faulted phase selection process is completed, the current waveform can be properly processed by applying both the Continuous Wavelet Transform (CWT) (or alternatively the discrete Fourier Transfor (DFT)) [25] and the Hilbert Trasform (HT) [26] (see Appendix A), in order to highlight the frequency of the charge transient. [17].…”

Overcoming the Limits of the Charge Transient Fault Location Algorithm by the Artificial Neural Network

In this paper, two algorithms for single-ended fault location are presented with reference to the unearthed sub-transmission Italian grid (with a voltage level of 60 kV). Both algorithms deal with the correlation between the ground capacitance charging frequency of sound phases and the fault position. In the former, the frequency response of a lumped parameter circuit in the Laplace domain is linked to the fault distance. With such a simplified lumped parameter circuit, the average error in locating a phase-to-ground (PtG) short circuit is 5.18% (total overhead line length equal to 60 km). Since this error is too high, another approach is presented. In this second algorithm, the frequency spectra of the transient current waveforms are used as a database for the training of an Artificial Neural Network (ANN). With this approach, the average error decreases significantly up to 0.36%. The fault location accuracies of the two proposed methods are compared in order to reveal their strengths and weaknesses. The developed procedures are applied to a single-circuit overhead line and to a double-circuit one, both modelled in the EMTP-rv environment, whereas the fault location algorithms are implemented in the MATLAB environment (for the ANN-based algorithm, the Deep Learning toolbox is used).
