摘要：This article presents one of the most current methods and a computer program for evaluation of the reliability of power supply of recipients in middle voltage grids in the country.It is an extension of the NIEZ method and program,developed at the Power Engineering Institute of the Silesian University of Technology for the HV and 110 kV transmission grid.The main assumptions of the method and computational model,as well as exemplary calculation results for a medium voltage grid model section,are presented.
