Rezumat
Pierderile de energie electrica în sistemele de transport si de distributie a energiei electrice reprezinta unul
dintre indicatorii utilizati pentru evaluarea performantei operatorilor din sistemul electroenergetic. Reducerea componentei
tehnice a pierderilor este una idntre preocuparile importante a specialistilor din domeniu. Cresterea ponderii receptoarelor
neliniare si a nesimetriei curentilor electrici, în special în zona tensiunilor medii si joase, determina necesitatea evaluarii
nivelului pierderilor în prezenta perturbatiilor din retea. În cadrul lucrarii este dezvoltata o metoda de analiza a pierderilor de
putere si de energie, în regim sinusoidal dar nesimetric pentru retele electrice de distributie

Abstract
Losses in electricity transmission systems and distribution of electrical energy is one of the indicators used to
assess the performance of the electricity system operators. Reduction of losses technical component is one dintre major
concerns of specialists in this field. Increasing share of non-linear receivers and unsymmetrical electric currents, particularly
low and medium voltages, determined the need to evaluate the losses level in the presence of disturbances in the network.
The work developed a method of analysis of the power and energy losses, but the sine nesimetric for electrical distribution
networks.
