Имитационное моделирование цифровой подстанции

Abstract

Работа посвящена созданию модели цифровой подстанции, в которой отражен процесс обмена информации между различными уровнями системы на основе протоколов стандарта МЭК 61850, и проведению с ней различных экспериментов. Для решения поставленных задач рассмотрены структура цифровой подстанции, стандарт МЭК 61580 и протоколы передачи данных: SV, GOOSE, MMS; проведён анализ основ релейной защиты и устройств РЗА с точки зрения основных угроз для кибербезопасности предприятия и цифровой подстанции и определены методы защиты против них. В системе имитационного моделирования AnyLogic построена модель, в которой происходит обмен информации между объектами в соответствии со стандартом. Проведены эксперименты с моделью, целью которых был анализ сетевого трафика в цифровой подстанции при различных показателях.

This work is devoted to the creation of a digital model of a substation reflecting the process of information exchange between different levels of the system based on protocols of the IEC 61850 standard, and conducting various experiments with it. Tasks that were solved during the work: analysis of the structure of the digital substation and the IEC 61580 standard; viewing data on transmission protocols: SV, GOOSE, MMS; analysis of information about the basics of relay protection and RPA devices from the viewpoint of the main threats to the cybersecurity of the enterprise and the digital substation and methods of protection against them. A model was built in the AnyLogic modeling system in which information exchange between objects is carried out in accordance with the standard. Experiments were conducted with the model, the purpose of which was to analyze network traffic at a digital substation according to various indicators.
