Actualmente, el Sistema Aislado Cayo Santa María consiste en una moderna subestación que se encarga de brindar el suministro de energía eléctrica al polo turístico, para lo cual debe garantizar un servicio eléctrico confiable para una carga que no admite interrupciones y que crece cada vez más. día.

The construction of new hotels in the region has required an increase in generation to achieve constant and safe electricity service. Two sets of Chinese batteries MTU were installed three years ago, each with six 2.1 MW machines. The batteries have a set of modern protections in the part corresponding to the so-called container. These protections have adjustment parameters, but it was necessary to carry out a technical-scientific study to ensure that their behavior was correct in accordance with the electrical network where they are installed and also, thereby guarantee adequate coordination with the the rest of the existing protections in the substation outputs.

The work shows the results of the calculations of the protection adjustment parameters according to the changes that have occurred in the network to guarantee a quality service. This research was feasible since the simulations and all the calculations were carried out with the PSX software. Once the protections have been adjusted, it was achieved that it will be guaranteed to protect the system against contingencies and avoid incorrect trips during the normal operation of the system.present, the Cayo Santa María Isolated System consists of a modern substation which is responsible for offering the supply of electrical energy to the tourist pole, for which it must guarantee a reliable electrical service for a load that does not admit interruptions and that grows more every day.

El trabajo muestra los resultados de los cálculos de los parámetros de ajuste de protección según los cambios que se han producido en la red para garantizar un servicio de calidad. Esta investigación fue factible ya que las simulaciones y todos los cálculos se realizaron con el software PSX. Una vez ajustadas las protecciones, se logró que se garantice proteger el sistema contra contingencias y evitar disparos incorrectos durante el normal funcionamiento del sistema.
