Abstract

Тема выпускной квалификационной работы: «Выбор оборудования и расчёт электрических режимов электроэнергетической системы 330/110 кВ».В выполняемой работе проводились исследования процессов, происходящих в электроэнергетической системе напряжениями 330 и 110 кВ. В ходе выполнения работы были проделаны следующие этапы:1.Выбор силового оборудования системы, а именно трансформаторы и автотрансформаторы, провода воздушных линий электропередачи;2.Ручной расчет установившегося режима электроэнергетической системы, а также расчет режима в программном комплексе «RastrWin»;3.Определение токов и напряжений короткого замыкания при возникновении не симметрии в сети с помощью ручного расчета и с помощью программного комплекса «EMTP»;4.Расчет динамической устойчивости системы при КЗ в заданной точке в программном комплексе «Dymola», определение предельного времени отключения КЗ и проведение мероприятий по увеличению устойчивости.

The theme of the final qualifying work: «Selection of equipment and calculation of electrical modes of the electric power system 330/110 kV».The processes in the electric power system are studied in this work. In the course of the work, the following stages were carried out:1.Selection of power equipment of the system, namely transformers and auto-transformers, wires of overhead power lines;2.Manual calculation of the steady state mode of the electric power system, as well as the calculation of the mode in the RastrWin software package;3.Determination of short circuit currents and voltages in the event of an asymmetric short circuit using manual calculation and using the EMTP software package;4.Calculation of the dynamic stability of the system during a short circuit at a given point in the Dymola software package, determining the limiting time for short circuit disconnection and taking measures to increase stability.
