Оценка обеспечения безотказности электроснабжения потребителей при использовании в системе временной избыточности

Оценка обеспечения безотказности электроснабжения потребителей при использовании в системе временной избыточности

Abstract

Существующие методы обеспечения безотказности систем электроснабжения предусматривают введение избыточных мощностей, что ведет к росту объёмов энергопотребления и эксплуатационных расходов. В статье описывается взаимодействие элементов электрической системы в условиях временной избыточности на основе теории случайных импульсных потоков. Приведён пример расчета изменения параметров схемы электроснабжения с установкой в ней электрического накопителя. Проанализировано соответствие расчетных и теоретических параметров; дана оценка соответствия полученных результатов технологически необходимым. Полученные результаты позволяют отследить изменение влияния временной избыточности на безотказность электроснабжения потребителя при различных параметрах системы, используемого накопителя и длительностях отказов.

The existing methods of reliability provide for the introduction of excess capacity. This leads to growth of the volume of energy consumption and operating costs. The description is based on the mathematical apparatus of the theory of random impulse flows. The example of calculation of parameters of the scheme with the installation of an accumulator is given. The correspondence of the calculated and theoretical parameters is analyzed; the received results are estimated. The results allow to monitor the following: the changing influence of temporal redundancy for reliability of power supply for various parameters of the system; the drive and length of failures.
