Introduction of the crowbar resistor:
Crowbar resistors are three phase resistance banks which are connected to the rotor windings of the DFIG (Doubly-Feed Induction Generator) such as wind power generator.
The crowbar resistors should be high enough to limit the short circuit rotor current and also they should be low enough to avoid too high voltage in the rotor circuit. The crowbar resistor should be designed with low inductance and capable of handling very high currents for short periods.
Power parts with in the Inverter can be damaged as a result of over voltages power supply failures or other faults. Therefore an extensive protection system should be there to reduce the likelihood of damage to the inverter. For this reasons Each Thyristor Control Cabinet (TCC) is provided with a built in protection system called IPS (Inverter Protection System).
