Substation's Switchgear's Reliability Evaluation as a Part of Transmission, Distribution and Generation Modeling Software

The paper gives the main idea of substation’s switchgear’s reliability evaluation module as a part of software that was developed in Riga Technical University in frames of project “Information technol-ogy to ensure the sustainability of generation and trans-mission grid”. The module allows easily evaluate switchgear’s up-state’s probability and interruption time for large amount of different types of switchgears by switchgear’s bay’s faults and elements standardiza-tion. Also it is possible to evaluate energy not supplied and costs related to energy not supplied due to switch-gear’s fault
