Análisis de transferencias de carga en media tensión del sistema de distribución de la Centrosur para contingencias N-1 y N-2

Abstract

Improving reliability and reducing reply times in the electric distribution system are of interest to electric companies today. In the context, the electric company CENTROSUR uses simulation tools as part of its strategy to achieve these objectives. This degree dissertation focuses on the study of contingencies, which arises as a response to the possibility of disconnection of various elements in the distribution network of the electric company CENTROSUR. Contingency N-1, in the context of this study, involves the disconnection of two the sub-transmission lines in the network as part of an operational strategy. On the other hand, contingency N-2 involves the disconnection of the power transformer located at substation 08 on the distribution system. To guarantee the integrity of the system and continuity in the provision of services, it is necessary to carry out a process that includes the transfer of load from the existing feeders at substation 08 to neighboring substations. The study focuses on an analysis of the distribution system,

specifically on the evaluation of load transfers to the N-2 contingency. To carry out this analy- sis, the ADMS and Cymdist tools are used, which allow the respective operational maneuvers

to be carried out in cases of contingencies. The aim is to identify similarities and differences in the results of both programs, which will contribute to the improvement of the contingency management in the distribution system of the CENTROSUR electric company.
