Reducerea pierderilor tehnice de putere reprezinta o problema majora in planificarea si exploatarea retelelor de
distributie cu importante implicatii tehnico-economice. Tinand seama de volumul mare de informatii necesar metodelor
clasice pentru evaluarea pierderilor tehnice de putere si energie din retelele publice de joasa tensiune, in lucrare sunt
prezentate modele matematice si programe de calcul ale acestora utilizand profilele tip de sarcina. In final, pentru a
sublinia precizia metodologiei descrise este analizata o retea reala de joasa tensiune.

Abstract
In distribution networks, the reduction of technical power losses represents an major issue during planning and
operation with important technical and economical implications. Taking into account the high volume of required
information used for technical power losses evaluation with traditional methods from low voltage (LV) public distribution
networks, in the paper, some mathematical models and application to power and energy losses computation using typical
load profiles, are presented. Finally, to emphasize the methods described accuracy a real LV networks are analysed.
