Balance of loads in the distribution circuits of an isolated electrical system guaranteeing safe operation in the occurrences of faults. Ing. Desarro. [online]. 2019, vol.37, n.1, pp.1-19.

The tourist destination Cayo Santamaría in the province of Villa Clara, Cuba, has aconstructive accelerated development. Currently does not have interconnection with the national electrical system that ensures the autonomy of the electrical system, and there is a great difference in the electric power circulating through of the distribution circuits that feed the loads. An analysis that would deliver these loads evenly for connection to the distribution channels became necessary. Therefore, it is necessary an analysis that allows to distributing these loads in a uniform way for their connection to the distribution circuits.

This paper realize a study on the possible connection variants of the load groups of hotel centres to the distribution circuits, concluding which optimal variant to perform. It was analyzed system response from faults in the circuits, proposing solutions to extend the post-failure stability. The results obtained are a starting point for an optimal operation and more reliable of Cayo Santa María isolated system.
