Power swing is an undesirable variation in power flow. This can be caused by large disturbances in demand load, switching, disconnection or reclosing lines. This phenomenon may enter the zones of distance relays and cause relay malfunction leading to the disconnection of healthy lines and undermining network reliability. Accordingly, this paper presents a new power swing detection method based on the prediction of current signal with a GMDH (Group Method of Data Handling) artificial neural network. The main advantage of the proposed method over its counterparts is the immunity to noise effect in signals. In addition, the proposed method can detect stable, unstable, and multi-mode power swings and is capable of distinguishing them from the variety of permanent faults occurring simultaneously. The method is tested for different types of power swings and simultaneous faults using DIgSILENT and MATLAB, and compared with some latest power swing detection methods. The results demonstrate the superiority of the proposed method in terms of response time, the ability to detect power swings of different varieties, and the ability to detect different faults that may occur simultaneously with power swings.

“…However, it lacks the capability to detect unbalanced power swings. In [28], a method based on the theory of signal compression is proposed which requires a lower sampling rate. However, although lower sampling rate leads to high-speed fault detection, it also increases the likelihood of misdiagnosis.…”

“…The stable power swing phenomenon is generally produced during regular events of the power system, such as reclosing the power switches, overloading of lines, or disconnecting one of the parallel lines due to a fault. The most common type of power swing in power systems is the stable swing [32]. So, the performance of the proposed distance relay is evaluated under stable power swing.…”

“…The single line diagram of the IEEE-39 bus 60 Hz network is shown in Figure 26, where the voltage levels of this network are 345, 230, and 22 kV buses [34]. The distance relay R1, which protects the line between buses 28 and 29 (1 km line), is considered as a tested relay after applying the TCSC at the mid-point of that line according to [32,35]. Under α = 75 • and α = 90 • , it is observed that the conventional relay has falsely sensed such swing as a fault in the third zone.…”

This paper proposes an adaptive dynamic Mho distance relay based on a phase comparator scheme for protecting interconnected transmission networks compensated with a Thyristor Controlled Series Capacitor (TCSC). The proposed relay uses an impedance index factor to initiate the fault detection subroutine. The RMS of the positive sequence current of the faulted loop and the TCSC terminal current are compared for TCSC zone identification. A phase comparator for ground and phase distance elements is proposed, relying on the positive sequence voltage as a polarized memory quantity, while the operating and polarizing quantities are developed using estimated TCSC impedance to mitigate its negative impact. The proposed scheme is easy in implementation and independent on synchronized data transfer, as minimum communication requirements are needed. To evaluate the performance of the proposed scheme, extensive simulation studies were carried out on an IEEE9 bus system compensated with TCSC for different firing angles covering four modes of TCSC operations, different fault types, and fault locations. In addition, an IEEE-39 bus network, as a large interconnected system, is tested for validation purposes. The achieved results designate the precision of the proposed scheme. Moreover, the results indicate its effectiveness for fault resistance tolerance, close-in three phase faults, and stable power swing phenomenon compared with conventional relays.
