This paper presents a simple methodology for the formulation of accurate reliability equivalent models of LV and MV parts of larger power supply systems. Calculated failure rates and mean repair times of the equivalent part of the network are assigned to the corresponding bulk load supply point so that the original power supply system can be correctly represented by a reduced model during the conventional reliability analysis. The accuracy and effectiveness of the equivalenting methodology are demonstrated through a number of different scenarios applied to a test system, representing the typical UK distribution network configurations.
