Algoritm multicriterial de evaluare a punctelor critice din retelele de distributie

The establishment of the critical points in the power system is made according to the following main criteria: a) technical condition (physical condition, number of incidents, unavailability time, associated costs) b) operational importance c) electrical energy transit (past measured transit, forecast transit). Different sets of weighting coefficients are proposed and the sensibility of the algorithm to these coefficients is investigated. The paper demonstrates that these criteria are applicable also to power transformers, internai services, compensation facilities and telecommunication entities. Eventually, a maintenance strategy for different installations of the power system is propose
