Схемні рішення відкритих розподільних пристроїв з урахуванням живучості та післяаварійного відновлення підстанцій

Abstract

An approach to evaluating circuit configurations of outdoor switchgear substations is proposed, taking into account not only classical reliability and cost criteria, but also survivability, maintainability, damage localization, and post-emergency restoration speed. It is shown that under wartime risks the selection of an outdoor switchgear scheme should consider spatial vulnerability of equipment, sectionalization capability, feeder redundancy, power transit preservation, and restoration of power supply under limited resources. The feasibility of multicriteria comparison of single-busbar, sectionalized busbar, transfer-busbar, and high-reliability schemes is substantiated.
