Este tipo de generador tiene la capacidad de seguir generando cuando es desconectado de la red eléctrica principal. Esto permite que ante la ocurrencia de desastres naturales o de averías en la red, las zonas que queden aisladas del Sistema Eléctrico de Potencia puedan seguir siendo alimentadas por estos generadores. Para ello, es necesaria la implementación de métodos que permitan un control efectivo sobre la máquina, durante este modo de operación. En este articulo se analizan diferentes métodos para la detección del modo de operación en isla. Se presenta la simulación de dos métodos de detección de islas (MDI, por sus siglas en inglés), uno activo que mide la variación de la distorsión armónica total (THD, por sus siglas en inglés) de las corrientes de fase y uno pasivo que mide el cambio del rango de la frecuencia (ROCOF por sus siglas en inglés).]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT 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).]]></p></abstract>
