Abstract :This paper considers the impacts of the Static Var Compensator insert ignore into journalissuearticles values(SVC); and Static Synchronous Compensator insert ignore into journalissuearticles values(STATCOM); on stability of the wind farms based on fixed speed induction generators insert ignore into journalissuearticles values(FSIG); which are connected to power system, after a severe disturbance occurrence. Because of asynchronous characteristic of fixed speed induction generators, the instability in wind farms based on FSIG is severally created by the extreme reactive power absorption by FISG after fault. This phenomenon is a result of rotor slip of FISG increase during the fault, and consequently, the consumption of reactive power is raised. The comparison is made between the performances of the wind farm equipped by SVC and STATCOM to improve the wind farm stability during and after fault. The simulation results show both of the devices can enhance the system stability during and after disturbance, especially when the network is weak. It is shown that the STATCOM have a much better performance as compared to SVC to improve wind farm stability, and provided better reactive power support to networkKeywords : SVC, STATCOM, Stability, Wind Farm
