Power quality has been area very much based on measurements and observations. The major power quality issues is related to large difference between in the normal system and doubly fed Induction generator connected system. Power electronics and advanced control technologies have made it possible to reduce the power quality problems. Flexible AC transmission system is one aspect of the power electronics revolution that is taking place in all areas of electrical energy. The primary objective of applying a static compensator in a power system is to increase the power quality capability from the system comprising of Doubly Fed Induction Generator. The system model comprising of Doubly Fed Induction Generator (DFIG) and 48-Pulse voltage source converter based STATCOM is constructed using MATLAB/Simulink. The paper focuses on the design and evaluation of a control strategy for improving the quality of energy of a STATCOM Controlled grid-connected variable speed Doubly Fed Induction Generator (DFIG) wind energy conversion system. The proposed research work is carried to investigate the performance of Static synchronous Compensator within the power system using wavelet multi resolution analysis under various power quality problems. The simulation results showed that the proposed shunt compensator was efficient in mitigating the power quality problems. This approach is different from conventional methods and provides effective solution to analyses the power system networks under transients, faults and sudden load injections.
