BRAVO DE LAS CASAS, Marta Elena et al. Protections of Cayo Santa María Subestation. Energética [online]. 2018, vol.39, n.3, pp. 213-222. ISSN 1815-5901.

The Electric System Isolated Cayo Santa María (SEACSM), located in the north of province of Villa Clara, is of vital economic importance to Cuba. During 2013, a group of faults occurred that affected the electrical service provided to the hotel network. This system is weak (due to its condition isolated system) and any failure can lead to the total collapse of the system or loss of a considerable set of loads. That is why it is decided to install a modern substation, which opened in January 2015 to provide a more reliable and stable supply. In this paper we analyze the results of the calculation of the adjustment parameters of the MiCOM P142 and P143 protections of Areva T & D of the new substation, of a very modern technology, which ensure the stability and reliability of the system in four variants of possible operating and expanding the capacity of response before the occurrence of faults
