Comparative analysis of modern methods for assessing power supply reliability indicators

In electric power complexes and their separately functioning elements, emergency situations can occur up to several dozen times a year, which leads to significant undersupply of electricity to consumers and damage to energy supply organizations. Unreliability of elements of power supply systems causes serious consequences, so it is necessary to constantly study and improve methods for predicting the reliability, design, construction, installation and operation of electric power facilities with increased reliability. There are many methods for determining reliability indicators, but it is important to select the most suitable methods in each specific case. To do this, it is necessary to compare the methods and identify areas of their rational application. Analytical and combined groups of methods for assessing reliability indicators, features of their application are considered and the feasibility of using methods from each group in accordance with the classifications of failures is determined.
