This paper describes the methodology used by the authors for performing a predictive reliability assessment of a real distribution system of the USA. In the first stage of this approach, a Predictive Reliability Model (PRM) was developed by using five-year historical outage data, information about reliability improvement projects recently implemented by the distribution utility, distribution feeder...
This paper explains the development of a ten-year reliability improvement roadmap for a major distribution utility of the USA. First, a benchmark approach based on a survey of the reliability indices of 21 utilities of the USA and Canada was used to set the roadmap targets. Moreover, a historical outage analysis was performed to identify the main outage causes and potential reliability improvement...
In this work, functions of type-2 fuzzy numbers are analyzed. For the special case of interval type-2 fuzzy numbers, the type-2 membership function of the output variable is calculated using the lower and upper membership functions of the input variables and the vertex method. This procedure is used in an application where the type-2 fuzzy fault currents of an electric distribution system are calculated...
