“…In [15], a method was introduced which is dependent on the TKEO of zero sequence voltage (obtained from instantaneous values) and negative sequence current (obtained from phasor values) during power swing. In [16], a simple algorithm to detect symmetrical faults during power swing on a double circuit multi-terminal line was proposed. In [17], different wavelet types were used, such as Battle Lemarie Spline, Beylkin, Daubechies, and Symlet, for fault detection during power swing by extracting voltage and current signals.…”

In power systems, distance relays are commonly employed as the primary protection for transmission lines, and their operation is of utmost importance. Power swings are a type of phenomenon that can lead to improper functioning of conventional distance relays, posing a threat to the uninterrupted flow of electrical power. The occurrence of a power swing disrupts the impedance measured by the relay, causing it to deviate from the normal load condition and enter the relay tripping zones. This research paper introduces a novel method based on the Prony method for extracting current waveform components, enabling fault detection during power swings. Subsequently, the proposed method’s accuracy is assessed through simulations implemented on a nine-bus power system, involving three-phase current signal processing and the application of the proposed algorithm. Various fault scenarios encompassing varying fault distances from the relay position, fault resistances, and power angles within the 9-bus system are simulated to encompass a wide range of fault environments. The simulation results demonstrate the effectiveness of the proposed algorithm in detecting all types of faults, including symmetrical and asymmetrical faults, during power swings.

“…[4] presents one form of protection based on the dynamic state estimation method. Another approach to double circuit transmission line protection based on system impedance, varying power swing slip frequency, and infeed effect is presented in [5]. Double circuit transmission line protection based on the current differential method is one of the oldest methods of protection and continues to be used and even, in the case of short lines, dominates other protection schemes, since it is considered superior with respect to selectivity, sensitivity, stability and speed of operation as compared with other forms of protection.…”

This paper presents an impedance differential protection scheme for a double-circuit transmission line. Current and voltage measurements at both line ends enable the formulation of a differential impedance that serves as an effective protection standard for transmission lines. The proposed method takes into consideration the effects of the line’s shunt capacitance since it is based on the distributed parameter line model. The proposed protection system is able to detect the faults and also has the ability to determine the fault location. In addition, the relay offers dependability, and selectivity for differentiating between internal and external faults, thereby stays steady against external faults. The proposed method has been tested with varying fault resistances and under various fault conditions. The effectiveness, security, and dependability of the method are verified by the simulation results.

“…In [13], the PRONY method and the frequency components of the current signal excluding the constant value are used to identify faults from the PS. The authors in [14] introduce an algorithm for determining the fault and PS occurrences by considering the changes of the slip frequency and the system impedance. In [15] a setting‐free method based on the frequency components of three phase power is proposed to detect faults during the PS.…”

This study proposes a a novel efficient strategy for identifying symmetrical faults from power swings in order to improve the performance of distance relay. This method is based on two new indices and the use of adaptive linear neuron and moving window averaging technique, which is applied to the waveforms of the current. If the proposed algorithm detects power swings, it enables power swing blocking; and if it recognises the occurrence as a symmetrical fault, it resets the power swing blocking as quickly as possible. The efficiency of the proposed method has been tested in different conditions and compared to other methods from different points of view. Simulation results under different conditions in PSCAD and MATLAB software show that the proposed strategy is able to detect symmetrical faults from power swings with high accuracy. The high robustness of adaptive linear neuron and the moving window averaging technique has made the proposed method highly noise-resistant; and also, because of its low computational cost, the response speed of the proposed strategy is very high, and hence its practical implementation is simple.
