Abstract :
One of the most challenging tasks for network utilities is to reduce costs and improve reliability at the same time. In order to manage the task successfully advanced IT-solutions are needed providing reliability analysis as part of the planning process. This paper presents advanced reliability analysis for distribution network. A sophisticated failure rate model has been developed based on failure statistics of the network and engineer judgement. Practical fault management process and statistics has been analyzed in order to model the customer outage times in different fault situations. Outage cost model for different customer groups are used in order to reach financial results by the analysis. The practical implementation and some demonstration studies are presented in the end of the paper.
