Wind Generator Stabilization With Doubly-Fed Asynchronous Machine

This paper investigates the function of DASM (doubly-fed asynchronous machine) with emphasis placed on its ability to the stabilization of the power system including wind generators. P(active power) and Q(reactive power) compensation from DASM can be regulated independently through secondary-excitation controlling. Simulation results by PSCAD (power system computer aided design) show that DASM can restore the wind-generator system to a normal operating condition rapidly even following severe transmission-line failures
