Abstract:

The paper presents a method of harmonic mitigation for Permanent Magnet Synchronous Generator (PMSG) coupled wind turbine interconnected with the infinite grid. Two voltage source inverters one at generator side is connected as Voltage Source Inverter (VSI) to extract maximum power from fluctuating wind turbine using vector control strategy and the other inverter is connected to the grid side Voltage Source Inverter (VSI) which feeds the generated active power to the grid in addition to suppress harmonics at PCC point of common coupling. The grid side VSI is controlled by the Instantaneous Synchronous Component Theory technique. Thus, with the help of both VSIs the power quality is improved and the due Sinusoidal current signal is obtained at Unity Power Factor which is fed to the grid. The system model is developed in MATAB /SIMULINK to verify the effectiveness of the control strategies of both the inverters and the system as a whole. The result shows the effectiveness of harmonic mitigation in the system, while connecting the wind turbine with the grid.
