Weibull Analysis of Electricity Distribution Network Failures

Popis výsledku v původním jazyce

Common values used for reliability calculations in Czech Republic are based on exponential distribution of failure rates. Disadvantage of this approach is that failure probability (hazard function) is constant. Virtually all components wear-out, their reliability decreases with time. This paper intend to describe Weibull probability distribution function of Time-to-Failure (and failure rate), which in principle includes component's wear-out. Further (and mainly) we deal with calculations of Weibull parameters form failure database for power lines (both overhead and cables) and switching gear. Calculation was done on failure databases from almost all Czech electricity distribution companies and some Slovak ones. Gained values can be used e.g. for reliability calculations using MonteCarlo simulation method. Also database history is briefly described in this paper
