| Abstract |
Doubly Fed Induction Generators (DFIG) are nowadays widely used in variable speed wind power plants. The behaviour of these machines during grid failure is an important issue, since in case of under voltage of the mains it is not allowed to simply disconnect the turbine but it is mandatory that it keeps on delivering power to the mains supply system. To protect the rotor side converter, a crowbar at the rotor has to be switched on. The performance of an active crowbar during voltage dips is investigated for several parameter sets of machine, resistor and control. |
