description: This work is devoted to the calculation of the steady state modes of the system, the choice of equipment, the calculation of currents in case of an asymmetric short circuit and the calculation of the transient properties of the system. Tasks to be solved: 1. Selection of equipment for a given power system: generators, transformers, power lines, autotransformers. 2. Calculation and analysis of the steady state in the power system in program RastrWin. 3. Simulation of an asymmetric short circuit in the power system and development of measures to reduce short circuit currents in program Â«EMTPÂ». 4. Modeling the enterprise complex to improve the transient stability of a given power system in program Â«DymolaÂ». In the course of writing the work, the equipment corresponding to the given power system was selected. The calculation of the steady state showed that in order to reduce the voltage drop in the load nodes, it is necessary to install compensation means. Next, a single-phase short circuit was modeled and calculated, and measures were proposed to reduce currents to the level of a three-phase short circuit. When analyzing the transient properties of the system, it was found that the given power system has good transient stability in the event of a single-phase short circuit, so more severe accident conditions were chosen. Further, a set of measures was proposed to improve the transient stability of the system.
