Wind Energy Generation Systems (WEGS) are confronted with increasing demands for power quality and harmonic distortion control. With the advances in power electronics technology, the rapid growth of variable speed WEGS is now witnessed. However, the power quality still remains an important issue to be addressed thoroughly by researchers.
This thesis presents a comparative study on grid connected WECS having two different Wind Turbine Generator Systems (WTGS) using Induction Generator and Permanent Magnet Synchronous Generator. Two cases are compared examining the effect of proposed unconventional on both WTGS systems. Transient analysis are carried out under the condition of sudden short circuit disturbance and the performance of both systems is compared for active power, reactive power and speed control. The comparison also aims to present in a thorough and coherent way the aspects of power quality in terms of reduction in Total Harmonic Distortion (THD) at various fault locations and buses.
