Abstract
The Series Dynamic Braking Resistor (SDBR) helps in the post fault recovery of the wind generator system. This chapter investigates the best location of the SDBR in the Doubly Fed Induction Generator (DFIG) architecture, considering the best switching signal of the SDBR. In this chapter, three signals were investigated in switching the SDBR during transient conditions of the DFIG wind generator; the DC-link voltage, rotor current and grid voltage respectively. Also, three locations were considered in connecting the SDBR in the DFIG system; the stator, rotor and grid side converter respectively. Furthermore, the optimum size and best insertion time of the SDBR were investigated based on the most effective performance of the SDBR scheme considering its switching signal and position in the DFIG system. Simulations were run in Power System Computer Aided Design and Electromagnetic Transient Including DC (PSCAD/EMTDC). The results show that when the SDBR is connected at the stator of the DFIG wind generator and a grid voltage signal is used in its actuation, considering a fast insertion time and short duration of operation, the DFIG wind generator variables were quickly recovered during transient conditions.
