Abstract: This research presents the development of Hexagram converter based Interline Power Quality Conditioner (Hex-IPQC) for proposed Hex-IPQC controller transmission lines. To achieve higher level of control, intelligent Fuzzy Logic Control (FLC) is im grid connected wind farms. In this, 3-generators with 13-bus wind farm system have been considered for the implementation of plemented to monitor and control the Hex-IPQC system. The various load disturbances has been taken for the analysis of power quality improvement. Firstly, the simulation study is carried out to validate the experimental results of the proposed WFs. Dynamic simulation results indicates that proposed FLC controller provides right performance for the seamless control, over Hex-IPQC converter when power system instability is detected. The real and reactive power flow through the transmission lines improves and also improves the power quality in the grid tied WFs.
