%X 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.
