In the early development of wind energy, the majority of wind turbines were operated at constant
speed. Recently, the number of variable-speed wind turbines installed in wind farms has increased and more
wind turbine manufacturers are making variable-speed wind turbines. In this study maximum power control
of wind turbine and permanent magnet synchronous generator connected with two back to back voltage source
converters to grid are studied. Machine currents are controlled by indirect vector control method. In this
method, generator side converter controls the maximum excitation (air gap flux) by machine's d-axis current
and controls generator torque by machine's q-axis current. PMSG speed is controlled by Tip Speed Ratio (TSR)
upon the wind speed variations to generate the maximum output power. Grid side converter regulates the DC
link voltage and injective active power by d-axis current and regulates the injective reactive power by q-axis
current using simple control method P-Q. Simulation results depict that the proposed method operates properly.
Key words: Boost converter, maximum power point tracking, wind energy conversion system, , , ,
