• Presented paper utilizes a reasonable boost converter setup and a PI controller for a Wind Turbine connected to Permanent Magnet Synchronous Generator (PMSG) for grid coordinated operations. In view of inconstant flow of wind, wind turbine generator produces variable-voltage and variable frequency. A few unique strategies were utilized to change variable-voltage, variable-frequency to reliable constant-voltage, constant-frequency outputs. In variable speed operation, it is important to utilize power electronics converter as an interface between wind turbine and grid. Power converter comprises of an uncontrolled three-phase diode rectifier, a DC-DC boost converter and a three-phase inverter. In this work, PMSG which feeds an isolated load through a closed loop boost Converter maintaining constant output with reference value as error signal input to PI controller using Cohen-Coon tuning method. In this PI controller, DC link voltage is maintained at constant by varying duty ratio of switch and continuously detecting output voltage. Together with controller and boost converter we can effectively enhance output voltage and frequency of generator feeding isolated load. The overall system is simulated using MATLAB/ Simulink and results are compared with theoretical results.
