LEON VILTRE, Lesyani T.; HERNANDEZ AMADOR, Leonardo  y  AYBAR MEJIA, Miguel. Island detection methods in doubly fed induction generators. Energética [online]. 2019, vol.40, n.2, pp. 128-137. ISSN 1815-5901.

One of the most used wind generators is the doubly fed induction generator (DFIG). This type of generator has the capacity to continue generating when it is disconnected from the main electrical grid. This allows that in the event of natural disasters or breakdowns in the network, the areas that are isolated from the Electric Power System (SEP) can continue to be fed by these generators.For this, it is necessary to implement methods that allow effective control over the machine, during this mode of operation. In this article, different methods for the detection of island operation mode are analyzed. It presents the simulation of two methods of island detection (MDI), an active one that measures the variation of the total harmonic distortion (THD) of the phase currents and a passive one that measures the change of the frequency range (ROCOF).

Palabras clave : double-fed induction generator; island operation mode.
