Abstract

A quick post fault recovery of wind generator system could be achieved with the help of a series dynamic braking resistor (SDBR). This paper investigates the dynamics, size, optimal location of a series dynamic braking resistor in the Doubly Fed Induction Generator (DFIG) structure based on different switching strategy of the braking resistor. 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 to the DFIG, improved performance was achieved, however, the stator based SDBR topology in conjunction with a grid voltage actuating signal, fast insertion time and short duration of operation, quickly recovered the DFIG wind generator variables during transient conditions.
