description: The first stage of this work is selection of the main electrical equipment of the system: generator-transformer blocks, power transformers and autotransformers, wire sections of overhead power transmission lines, as well as their verification under normal and post-emergency conditions. After analyzing steady-state mode of the power supply system, need for installing compensating devices in load nodes to maintain the required voltage level, as well as adjusting on-load changing device of the transformers, was revealed. In minimum load mode, less reactive power compensation is required. Ð¡alculation of asymmetric short circuit was carried out analytically using the method of symmetric components, as well as using the EMTP ATP software, calculation results differ slightly. Analysis of transient stability revealed that the system has sufficient stability with a singleâphase short circuit, in this regard, a more severe emergency mode was considered - a three-phase short circuit, and measures were taken to increase transient stability of the system.
