Abstract

This paper is to analyse and find out a suitable statistical model for modelling failures of medium voltage overhead lines in Vietnam grid. Practical operation data is collected and filtered out in order to support modelling process. The Weibull distribution function is selected to study the rates occurrences of the grid failures with aging. Matlab software is utilized in all calculations for parameters of Weibull distribution. The result of the study is an appropriate approach for modelling failures of Vietnam’s distribution overhead lines and typical parameters for common distribution lines.
Keywords: Weibull distribution, medium voltage overhead line, modelling failure, parameters of Weibull distribution.
