“…Methods. Based on the presented results in [15,18] and obtained results in this study, Table 3 shows a comparison between the proposed method and other methods based on the di erent indices, including detection of symmetric fault from power swing, detection of asymmetric fault from power swing, simple simulation, and simple implementation.…”

“…According to Table 3, some methods such as the conventional blinder scheme cannot detect symmetrical fault [18]. Moreover, other methods like the SCV tracer cannot detect asymmetrical fault [18]. While symmetrical and asymmetrical faults with and without power swing are detected using the proposed GSZCM method.…”

“…e voltage and current phasor analysis has been used to detect the power swing, symmetric and asymmetric faults, and fault during power swing. It should be noted that the settings of this method are very di cult to identify the stable and unstable power swings [18]. In [19], Teager-Kaiser energy operator has been applied to instantaneous current signal for fault detection during power swing in the compensated transmission line with a thyristor-controlled series capacitor.…”

Nowadays, due to the entry of wind power plants into the power systems, which causes changes in the network parameters, power swing detection has become more important. Changes in the wind speed and noncontinuity of the wind power plants lead to changes in the power swing characteristic. Therefore, the impedance seen by the distance relay is changed, and so the maloperation of the relay during the stable power swing may occur. This paper proposes a new method to detect power fluctuations based on the synchronous generator speed while it is independent of the network parameters. Based on the proposed method, the generator speed at any moment does not pass through zero during the stable power swing. In contrast, it passes through zero by occurring fault types with high and low fault resistance, fault types during power swing, and an unstable power swing. Therefore, the method prevents maloperation of distance protection. It is worth noting that the proposed method is applicable for distance protection in any power system with and without wind power plants, such as in the distance protection of compensated transmission lines. The obtained results indicate that the proposed method detects power fluctuations in a short time.
