Power Quality Issues in Variable Speed Wind Turbine and Application of STATCOM

In this paper a 8.5KW rated PMSG based wind energy system is designed and its power quality issues are discussed. A diode-rectifier based topology is used with Boost converter for wind turbine. Possible solutions to mitigate the power quality problems are also defined. The best possible solution is by using FACTS devices. Here a STATCOM with DQ control is designed for application in wind system This shows that if we use STATCOM with the wind energy system then power quality issues can be mitigated. The system is simulated in MATLAB/SIMULINK environment.
