Выбор оборудования и расчёт ÑÐ»ÐµÐºÑ‚Ñ€Ð¸Ñ‡ÐµÑÐºÐ¸Ñ Ñ€ÐµÐ¶Ð¸Ð¼Ð¾Ð² районной электроэнергетической системы 220/110 кВ

Abstract

В работе была рассмотрена электроэнергетическая система 220/110 кВ, выполнение которой состоит из четырех этапов. На первом этапе проводится выбор оборудования, рассматриваемой электроэнергетической системы: трансформаторов, автотрансформаторов и ЛЭП. Вторым этапом был расчёт установившегося режима работы «вручную» и с помощью программного комплекса RastrWin. Третьим этапом работы был расчет токов однофазного короткого замыкания в конце первой линии, который проводится с помощью метода симметричных составляющих. На последнем этапе работы была исследована динамическая устойчивость системы в программном комплексе Dymola и рассмотрены меры по ее улучшению.

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.
