Применение микропроцессорных реле в системах управления и защит энергетического оборудования

Abstract

В статье рассмотрено применение микропроцессорных устройств релейной защиты в системах управления и защит энергетического оборудования, их основные функции и требования, предъявляемые к этим устройствам. Также для проверки соответствия требованиям и проверки правильности выполнения необходимых функций представлены результаты проведения опыта «Моделирование максимальной токовой защиты линии электропередач», «Моделирование токовой отсечки линии электропередач» и «Автоматическое включение резервного питания нагрузки».

The article concerns the application of microprocessor units of relay protection systems for control and protection of power equipment, their main functions and requirements for these devices. It also presents the results of the experiment "Modeling of maximum current protection of electric power lines", "Modeling of electric power line current cutoff" and "Automatic activation of load reserve power supply."
