Abstract: This paper presents a grid connected UPFC system for PMSG wind power network using a Trans Zsource converter. The Trans Z-source converter has a common stage buck boost converter to produce DC voltage from AC input voltage by stabilizing the shoot through state. In the proposed system, the changing in shoot-through state is used to keep trans Z-source voltage regulation with respect to d-q current is capable to take out the more power from the turbine (wind) and fed to grid. The proposed system with UPFC has higherefficiency performanceand cost effectivecompare with conventional Z source PMSG based UPFC system. Matlab simulations are carried out and results prove that proposed system is better.
