Сравнительный анализ режимов регулирования статического тиристорного компенсатора в системе электроснабжения дуговой сталеплавильной печи высокой мощности
Аннотация
Приведены основные результаты сравнительного анализа режимов работы статических тиристорных компенсаторов (СТК), устанавливаемых в системах электроснабжения мощных и сверхмощных дуговых сталеплавильных печей (ДСП). Рассмотрены классические режимы регулирования СТК, которые направлены на обеспечение нулевого потребления реактивной мощности из питающей сети и на поддержание неизменного уровня напряжения в точке общего подключения СТК и ДСП. Дополнительно в статье представлено описание разработанного режима регулирования СТК, который предназначен для контроля суммарной активной мощности дуг ДСП. Исследование влияния параметров питающей сети и режима регулирования СТК на электрические характеристики ДСП проведено с помощью математической модели электросталеплавильного комплекса «ДСП-120-СТК», разработанной в приложении Simulink математического пакета Matlab. По результатам эксперимента определены основные достоинства и недостатки рассмотренных режимов регулирования СТК, даны общие рекомендации по их применению.
