Abstract

In this study, three phase fault analysis of wind turbines consist of Doubly-Fed şnduction Generators (DFIGs) has been examined. The dynamic analysis of DFIG has been conducted by Reduced Order Model (ROM). Three Phase fault has been made in 34.5 kV bus, happended in three bus power systems. The three phase fault time has been choosen as 0.02 second, 0.05 second and 0.1 seconds. 154 kV bus voltage, 34.5 kV bus voltage, DFIG output voltage, DFIG angular speed, DFIG electrical torque and DFIG d-q axes stator and rotor current variations of system in different fault times has been examined. According to the results, it has been seen that three phase fault is especially effective upon 34.5 kV bus voltage and DFIG output voltage in different fault time´s analysis.
