Abstract

The paper presents a study for implementing a brake sequence for a small wind generator for regimes that exceeds the rated values. Considering data from a real wind generator, two scenarios are presented: first, during a strong wind gust both the electrical and the mechanical brakes are coupled and, for the second case, a fault in the permanent magnet synchronous generator (PMSG) is caused. This study allows the correct dimensioning of the electric brake load resistors, the setting of the values for the rotation speed at which the different brakes are coupled, in order to respect the structural imposed limits such as maximum current through the PMSG, the maximum torque supported by the wind turbine axis.
