A new control strategy for improving fault ride-through capability of wind farms composed of
fixed and variable speed wind generators has been proposed, in this study. In this new …

The technology of variable speed wind turbines is very promising in renewable power
generation. It is imperative for wind turbines to gain control after grid disturbances and …

With the increased integration of wind energy into power networks it has become more
important to have a reliable system for mitigating the fluctuations of output power supplied to …

The recently stipulated grid codes require wind generators to re-initiate normal power
production after grid voltage sag. This paper presents a comparative performance of two …

Recent wind farm grid codes require wind generators to ride through voltage sags, which
means that normal power production should be re-initiated once the nominal grid voltage is …

This paper presents new schemes for protecting power converters used in doubly fed
induction generator (DFIG) during a grid fault condition considering rotor current and DC-link …

This paper proposes an application of series dynamic braking resistor (SDBR) connected to
the stator side of a doubly fed induction generator (DFIG), for enhancing fault ride through …

The wind turbine generator system is the only generator unit in utility network where
