Проектирование сложной электроэнергетической системы 750/330 кВ

Abstract

Тема выпускной квалификационной работы: «Проектирование сложной электроэнергетической системы 750/330 кВ ».В ходе данной выпускной квалификационной работы для электроэнергетической системы, номинальные напряжения которой 750 кВ и 330 кВ, было выбрано оборудование, рассчитан установившийся режим, смоделировано двухфазное короткое замыкание на землю, проанализированы меры повышения динамической устойчивости.Данные цели была достигнуты путем выполнения следующих задач:1)Выбор основного оборудования (генераторы, трансформаторы, провода ЛЭП) с использованием справочной литературы;2)Расчет установившегося режима электроэнергетической системы аналитически и при помощи программного комплекса «RastrWin3»;3) Моделирование двухфазного короткого замыкания и расчет токов и напряжений в месте повреждения аналитически и при помощи программного комплекса «EMTP»;4) Анализ динамической устойчивости электроэнергетической системы и мер ее повышения с использованием программного комплекса «Dymola».В результате были оптимизированы максимальный и минимальный режимы работы энергосистемы, были рассмотрены различные меры повышения динамической устойчивости, было получено значение предельного времени отключения короткого замыкания для каждой из мер и без какой-либо из них.

The subject of the graduate qualification work is «Design of the 500/220 kV electric power system».In the course of this graduate qualification work, equipment was selected for an electric power system with rated voltages of 750 kV and 330 kV, the steady-state mode was calculated, a two-phase short circuit to ground was modeled, and measures to increase dynamic stability were analyzed.These goals were achieved by completing the following tasks:1) Selection of the main equipment (generators, transformers, power lines) using reference literature;2) Calculation of the steady-state mode of the electric power system analytically and using the software «RastrWin3»;3) Simulation of a two-phase short circuit and calculation of currents and voltages at the fault site analytically and using the software «EMTP»;4) Analysis of the dynamic stability of the electric power system and measures to improve it using the software «Dymola».As a result, the maximum and minimum operating modes of the power system were optimized, various measures to increase dynamic stability were considered, and the value of the maximum short-circuit shutdown time was obtained for each of the measures and without any of them.
