Abstract: The article considers the basic electrical network parameters in case of emergency conditions in oil refinery enterprises. A scheme of short circuit and the response of automatic transfer switch, and equivalent circuit for short-circuit current calculation have been provided. Basic physic technical dependencies for short-circuit current calculation have been suggested. The analyzed material comprises technical characteristics of automatic transfer equipment, relay protection and automatic equipment. Shown physical calculations of basic electrical network parameters for automatic transfer switch facilities exemplified by an electric substation of an oil refinery plant of the Republic of Bashkortostan with single current-limiting reactor. Recommended a selection method of relay protection and automatic equipment on the basis of cut-off sensitivity factor calculations and meeting technical demands of sensitivity. Provided calculations make it possible to create and implement innovative automatic transfer equipment switching over from operating emergency conditions in less than 1 second.
Key words: energy, power supply, relay protection, automatic equipment, single-way feed, automatic transfer switch, short circuit, oil extraction, cut-off sensitivity factor.
