Ð’ работе была раÑÑмотрена ÑлектроÑнергетичеÑÐºÐ°Ñ ÑиÑтема 220/110 кВ, выполнение которой ÑоÑтоит из четырех Ñтапов. Ðа первом Ñтапе проводитÑÑ Ð²Ñ‹Ð±Ð¾Ñ€ оборудованиÑ, раÑÑматриваемой ÑлектроÑнергетичеÑкой ÑиÑтемы: транÑформаторов, автотранÑформаторов и ЛÐП.

In work 220/110 kV electric power system was considered, the execution of which consists of four stages. At the first stage, the selection of equipment is considered: transformers, autotransformers and power lines. The second stage was the calculation of the steady state operation "manually" and using the RastrWin software package. The third stage of work was the calculation of single-phase short-circuit currents at the end of the first line, which is carried out using the method of symmetrical components. At the last stage of work, the dynamic stability of the system in the Dymola software package was investigated and measures for its improvement were considered.
