Abstract
Transients in power system pose severe threat to the operation and control mechanism. various abnormal conditions categorized under short circuit faults have adverse effects on the system operation. Short circuit faults namely a single L-G fault and 3-Φ short circuit faults are to be given major importance to ensure reliability of the overall system. It is well known that these short circuit faults rather symmetrical or unsymmetrical are to be cleared as soon as possible. The clearing time of these fault currents is of major importance and emphasis has to be given on generator types which are capable of clearing such faults in a quick time. The paper focuses on two concerned generator’s mainly used in the wind energy sector namely a DFIG type and the PMSG. Both these WTG (Wind Turbine Generator) topology are analysed for their short circuit capability in terms of impact of short circuit faults, time for recovery after occurrence of short circuit fault and for system oscillations if any.
