The concepts of power system stability& oscillation, different types of wind turbine generators (WTGs) are briefly introduced. The vector control of double feed induction generator (DFIG) rapidly response to active and reactive power control separately. In This paper the impacts of DFIG wind turbine generator on power system oscillation damping has been investigated By modifying of RSC, and GSC controllers and utilize a new algorithm control signal to reactive power controller to enhancement power system oscillation damping characteristics without effecting to its active power generation. Then, Finally, For this purpose, Besides, time domain simulations were carried out by interconnection of DFIG at middle of 132KV transmission line connected Karbala north network and Alahkader network in order to verify the conclusions inferred from three cases of the fault (1-L-G, 2-L-G, 3-L-G) were applied at 3sec and cleared after 50msec at transmission line in which power system oscillation occurs and damped with DFIG. By using PSCAD/EMTDC, different simulation results are presented based on various scenarios.
