RELRAD-an analytical approach for distribution system reliability assessment

An overview of the distribution system planning model used by Norwegian utilities with emphasis on the approach used for reliability analysis, RELRAD (reliability in radial systems), is presented. The use of RELRAD is placed within the framework of distribution system planning. Two case studies of typical Norwegian MV systems are included: the benefit of automation and remote control in a rural overhead system, and the impact of reserve cable in an urban cable system.<
