Abstract

Тема выпускной квалификационной работы: «Выбор оборудования и расчёт электрических режимов электроэнергетической системы 220/110 кВ». Данная работа посвящена изучению и исследованию электроэнергетической системы 220/110 кВ. Задачи, которые решались в ходе исследования: 1. Выбор оборудования электроэнергетической системы. 2. Расчет установившегося режима работы электроэнергетической системы. 3. Расчет токов несимметричного короткого замыкания. 4. Расчет динамической устойчивости, а также меры её повышения. Работа выполнена с применением программного комплекса «Rastr Win» для расчета установившегося режима работы. В результате расчета получены значения активной и реактивной мощностей, протекающих через элементы системы, а также значения напряжений в узлах. Для расчета динамической устойчивости использовано программное обеспечение «Dymola», при помощи которого определено предельное время отключения короткого замыкания. В результате был проанализирован расчет установившегося режима, разработаны эффективные меры для оптимизации перетоков реактивной мощности, а также для поддержания необходимого уровня напряжений в уз-лах нагрузки. На основании полученного времени отключения короткого замыкания были предприняты меры для повышения динамической устойчивости.

The subject of the graduate qualification work is: “Selection of equipment and calculation of electrical modes of the electric power system 220/110 kV”. This work is devoted to the study and research of the electric power system 220/110 kV. Tasks that were solved in the course of the study: 1. Selection of electric power system equipment. 2. Calculation of the established operating mode of the electric power system. 3. Calculation of asymmetric short-circuit currents. 4. Calculation of dynamic stability, as well as measures to improve it. The work was performed using the software package “Rastr Win” to calculate the established operating mode. As a result of the calculation, the values of the active and reactive powers flowing through the elements of the system, as well as the voltage levels in the nodes, were obtained. To calculate the dynamic stability, the “Dymola” software was used, with the help of which the limiting time of short-circuit disconnection was determined. As a result, the calculation of the established operating mode was analyzed, effective measures were developed to optimize reactive power flows, as well as to maintain the necessary voltage level at the load nodes. Based on the obtained short-circuit breaking time, measures were taken to increase the dynamic stability.
