25-43 STUDIU DE SOLUȚIE PRIVIND RACORDAREA UNEI CENTRALE ELECTRICE EOLIENE DE 20 MW partea I-a

ETUDE DE RACCORDEMENT D’UNE FERME
EOLIENNE DE 20 MW – Partie I-la
L’article présente les solutions possibles de raccordement au système
électro énergétique national (SEN) de la ferme éolienne de Nufăru, dép. de
Tulcea ayant une puissance installée de 20 MW. Les calculs de circulation des
puissances sont effectués sur le réseau à N éléments et les réseaux à N-1
éléments, en fonction des contingences prises en compte.
Mots clés : parcs éoliens, puissance
Cuvinte cheie: parcuri eoliene, circulaţii de puteri

19-39 SCHEME DE ALIMENTARE A SERVICIILOR INTERNE DINTR-O HIDROCENTRALĂ

ANCILLARY SERVICES ELECTRIC DIAGRAM ANALYSIS
AT A HYDROPOWER PLANT
The paper deals with the ancillary services analysis and with the
replacement of electrical equipment due to the short circuit power changes
imposed by the replacement of the transformers T1 and TSI-1 in the
hydropower plant DIMITRIE LEONIDA.
Keywords: domestic services, short-circuit currents
Cuvinte cheie: servicii interne, curenţi de scurtcircuit

19-40 STABILIREA ORDINII LUCRĂRILOR DE MENTENANŢĂ Partea 1-a

SUBSTATION MAINTENANCE SCHEDULING
The establishment of the maintenance activity in the power system is
made according to the following main criteria: technical condition, operational
importance, electrical energy transit, strategical importance. 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, internal services, compensation facilities
and telecommunication entities. Eventually, a maintenance strategy for different
installations of the power system is proposed.
Keywords: maintenance, ranking, criticality
Cuvinte cheie: mentenanţă, ierarhizare, criticitate
