Lucrarea dezvolta un model matematic de stabilire a numarului optim de interventii, numite reinnoiri, pentru
mentenanta preventiva a sistemelor de distributie a energiei electrice. Modelul are la baza sa, functia de fiabilitate de tip
Weibull, stabilita pentru sistemul in studiu, in baza datelor statistice privind incidentele, interventiile si costurile acestora.
Modelul optimizarii fiabilitatii bazate pe mentenanta, este aplicat pe o linie electrica aeriana LEA 20 kV si a fost
solutionata in baza mediului de programare MATLab 7.0.

Abstract
The paper develops a mathematical model for determining the optimal number of interventions, called
renewals, for preventive maintenance of electrical power distribution. The model its based on its type Weibull reliability
function which was established for the study system, based on statistical data on incidence, interventions and their cost.
The optimization model of maintenance based on reliability has been applied to the situation to a 20 kV overhead
transmission line and was resolved in the programming environment MATLab 7.0.
