Abstract :
This paper proposes Voltage Oriented Controller based Statcom connected at PCC with grid connected fixed speed induction generator. The Performance of Wind turbine System connected utility grid using the proposed control strategy is analyzed under various abnormal conditions using MATLAB/SIMULINK Tool Box. The effect of unbalanced and Non sinusoidal current drawing loads connected at Point of Interconnection is analyzed on the grid side and on the source side by the proposed current control strategy. The simulation results show that the proposed controller effectively reduces the distortions and unbalanced effect on the grid side and improves the wind farm voltage and current waveforms at PCC to improve the Power Quality. The THD Percentage of Grid utility Current is compared with and without Statcom to meet the IEEE-519-1992 Standards.
