Voltage Swell mitigation in Wind Farm System.

As the wind power penetration into the grid is increasing quickly, the influence of wind turbine on the power quality is becoming an important issue. Wind power penetration is the impact on power system stability. Power quality problems such as voltage sag and swell are some major concern. In this paper voltage swell issues is analyzed. Wind turbine connected to squirrel cage induction generator is modelled using PSCAD simulation software to analyse the said issues where STATCOM is introduced as an active voltage and reactive power supporter to increase the power system stability. STATCOM unit is developed to inject reactive power for mitigation of power quality problems and to get stable grid operation.
