Recently, there has been a significant increase of oil and gas production along with an increase of energy consumption and the complexity of distribution networks. All these factors lead to a decrease of power supply reliability, as a result of which the number of damages, such as various types of short circuits, increases per year. It leads to significant economic losses due to prolonged downtime of electrical equipment. The authors of the article consider the problem of testing relay protection and automation of the distribution network. A high-speed automatic reserve input complex (HSARIC) – is a digital model designed for analyzing and configuring various device parameters, such as response time or sensitivity to a certain type of short circuit. The main advantage of the digital twin is testing in a software package, that is, a real synchronous motor will not be intentionally subjected to excessive thermal and electro-dynamic effects. The study of the developed (HSARIC) model showed the permissible response time and registration of all types of short circuits, thus providing an almost instantaneous transition to a backup source and ensuring reliable power supply.
