Oil and natural gas are very important energy sources on the planet, representing a very significant percentage in the energy matrix, not only in Brazil, but also worldwide. In this context has an extremely privileged geographic position, a fact that was reinforced when, in 2007, the discovery of pre-salt reserves was announced, where it is estimated the presence of up to 176 billion barrels of oil equivalent. For the exploration of this reservoir, the development of new offshore platforms is planned, mainly FPSOs - Floating Production Storage and Offloading, which rely on highly complex industrial systems, requiring systems of great power, with large machines and, consequently, high-capacity electrical generators. Thus, this work aims to model the isolated electrical system of an FPSO in order to be able to carry out power flow and short circuit studies quickly and effectively. The methodology consists of using real data from an oil platform, modeling the system using OpenDSS software and, when possible, comparing results obtained from other models or conventional values found in the literature.
