“…According to the study's results [4], the automatic reclosing devices used in the electric network of Mongolia were studied in detail in terms of their type, element base, and year of use. In 90% of the electric network of the "Khangai region," RPV-58 and RPV-358 electromechanical relays manufactured in Russia are used.…”

In order to improve the reliability of the power system and provide uninterrupted power to the consumer, automatic reclosing (ARC) devices are often used in overhead power lines. On top of that, the condition of short-circuit elimination or removal during ARC recloser depends on many random factors. In this article, the number of outages of 110 kV overhead lines in the Khangai region of Mongolia was studied, and the statistics of ARC device operation were compared with international standards. Also, from the works produced by scientists from foreign countries, the development level and innovative trends of ARC devices were compared and studied, and the opportunity to introduce them to Mongolia's grid system was sought. Furthermore, the 110 kV transmission lines outage and the operation of the ARC devices installed in the Khangai region of Mongolia were studied. Hence, the average operation success rate of the ARC device in the last ten years was 76%. It was also found that the number of outages of 110 kV power lines is 8 per year on average, which is 2 -3 times higher than the international norm. Eventually, the power grid scheme of the Khangai region, especially the Bulgan-Murun 110 kV distribution network, was modelled by Digsilent Powerfactory by including the features of Mongolia's power transmission network, and the operation of the model was checked by the load flow function of the software.

This paper presents a reliable and fast index to detect the instant of arc extinction for adaptive single-pole automatic reclosing (ASPAR). The proposed method is a simple technique for ASPAR on shunt compensated transmission lines using the Hilbert–Huang Transform (HHT). The HHT method is a combination of the empirical mode decomposition (EMD) and the Hilbert transform (HT). The first intrinsic mode function (IMF1) decomposed by EMD, which contains high frequencies of the faulty phase voltage, was used to calculate the proposed index. HT calculates the first IMF spectrum in the time-frequency domain. The presented index is the sum of all frequency contents below 55 Hz, which remains very low until the fault clearance. The proposed method uses a global threshold level and therefore no adjustment is needed for different transmission systems. This method is effective for various system configurations including different fault locations, line loading, and various shunt reactor configurations, designs, compensation rates, and placement. The performance of the method was verified using 324 test cases simulated in electromagnetic transient program (EMTP) related to a 345 kV transmission line. For all the test cases, the algorithm successfully operated with an average reclosing time delay of 32 ms.

The integration of distributed generators has changed the paradigm of modern power transmission systems. To cope with energy demands, electrical networks emphasize the efficient utilization of power transmission. Thus, high-voltage DC (HVDC) and hybrid (AC/DC) transmission systems are also getting attention owing to their high efficiency in addition to the widely adopted high-voltage AC (HVAC) systems. Most faults in the bulk of transmission lines are temporary or intermittent. Auto-reclosing schemes can be used to prevent these faults. However, conventional auto-reclosing schemes based on constant dead time cannot recognize the fault nature within the assigned duration. Consequently, the accuracy of power grids can be compromised. Therefore, adaptive auto-reclosing schemes are convenient for overcoming the issues caused by the rapid restoration of faulty power lines. This can enhance system reliability and avoid power failures and blackouts. This study is based on a systematic, detailed, and thorough research review of the existing auto-reclosing schemes in all three power transmission lines, i.e., AC, DC, and hybrid (AC/DC). Subsequently, a critical analysis has been performed to assess the pros and cons of each existing adaptive auto-reclosing scheme. Finally, future recommendations are presented to improve adaptive auto-reclosing schemes in each medium.
