Abstract

UA: Проведено аналіз недоліків мікропроцесорних систем релейного захисту й автоматики для енергосистем залізничного транспорту та можливості підвищення їх надійності за допомогою методу дублювання як апаратних, так і програмних засобів, а також розрахунок надійності досліджуваних структур.

EN: The analysis of faults of microprocessors relay protection and automation of energy systems for railway transport faults and opportunities to increase their reliability by duplicating the method as a hardware so are software and calculation of reliability of structures that are investigated. The technical level of microprocessor devices of relay protection and automation usually considered from several positions: technical excellence and reliability of the devices, microprocessor-based protective relaying and automation technology level, which determines the performance of the system microprocessor relay protection and automation algorithms embedded security and automation; functionality of microprocessor relay protection systems and automation; possibility of integrating relaying and automation microprocessor systems in other systems. Invalid action relaying is one of the main causes of severe accidents that occasionally occur in energy systems - max globally. Therefore, the reliability of relay protection largely depends on the reliability of the entire grid. Previously developed methods to increase reliability of attitude to the old element base and microprocessor devices of relay protection and automation with a number of features that can not be taken into account in the calculation of these methods. It is necessary to develop new approaches to design microprocessor devices of relay protection and automation and methodology for assessing the performance reliability of these systems.
