Abstract

Problem statement: An inherent problem with wind turbine power generation systems is the low power quality due to intermittent power generation in these systems. This not only affects the power generation but also the grid it is connected to. Approach: In this study a configuration consisting of a 6MW Wind Farm based on conventional Fixed Speed Induction Generator is analyzed. To improve the transient stability in the wind turbine generator a STATCOM is introduced in the system as an active voltage/var supporter. The impact of the introduced STATCOM and subsequent performance improvement in the power quality is studied. Results and Conclusion: The improved short-term voltage obtained when a STATCOM is introduced under various wind speed conditions is quantified. It is proved that STATCOM has a direct impact on reliability, however SVC needsto be studied due to their lower cost.
