“…However, for the most part, such technical solutions are used in the design of new microprocessor protection systems for general industrial three-phase cable or overhead power lines and cannot be used in our case with a single-phase load (railway overhead system) and a non-standard voltage level U = 27.5 kV. Separately, I would like to note interesting from the point of view of similarity problems of the article [12] [13].…”

The article discusses the possibility of further modernization of the standard microprocessor relay protection of AC overhead system feeders DPA-27.5-TNF, which is operated on the Trans-Baikal Railway by creating an additional automated system of unified templates necessary for the occurrence of "trainability" elements. The templates will be formed via a separate dedicated channel for transmission, processing and storage of the necessary information, not related to the operation of the terminal, with its subsequent visualization at the workplace of the duty personnel of traction substations, together with information from the "GID" software received via another dedicated wired channel. With the help of such a base of unified preset templates, in the future, it will be possible not only to identify the specific causes of each emergency shutdown but also to reduce their number by dynamically adjusting the existing presets of the standard operation algorithm.
