BRAVO DE LAS CASAS, Marta y YANEZ BOZA, Yumil. CHALLENGES OF DISTRIBUTED GENERATION ON THE ELECTRIC PROTECTION IN DISTRIBUTION NETWORKS. Ingeniare. Rev. chil. ing. [online]. 2009, vol.17, n.1, pp. 101-107. ISSN 0718-3305. http://dx.doi.org/10.4067/S0718-33052009000100011.
The distribution networks have been designed so that the power flows in a single direction. When the Distributed Generation is introduced this consideration is no longer valid. Distributed Generation will bring new challenges for the operation and the design of the network. One of the most critical areas affected is the electric protection. This paper discusses issues of how the adjustments of the electric protection are affected when the Distributed Generation is introduced in a distribution network. For this purpose, the network was simulated with the help of the software named PSX. The generation was connected in different places, with different capacities and types. The levels of short circuits were calculated in the different scenarios in which the protections were adjusted. A set of interesting results was obtained, which can lead to new strategies in what concerns to these protections.
