Substation reliability evaluation in the context of the stability prediction of power grids [PDF]
Bulletin of the Polish Academy of Sciences: Technical Sciences, 2020 The aim of the presented work was to examine the reliability assessment model on the example of a selected power grid object. The analyzed object was tested based on assumptions about technological breaks that were caused by overvoltage, among others ...
