Abstract:
In this paper, three different impedance source inverters: Z-source inverter,
EZ- source inverter, TZ-Source for wind energy conversion system (WECS)
were investigated. Total output power and THD of each of these systems are
calculated. The proposed system can boost the output voltage effectively
when the low output voltage of the generator is available at low wind speed.
This system has higher performance, less components, increased efficiency
and reduced cost. These features make the proposed TZSI based system
suitable for the wind conversion systems. MATLAB simulink model for
wind generator system is developed and simulation studies are successfully
performed. The simulation is done using MATLAB and the simulation
results are presented. This comparison shows that the TZ-source inverter is
very promising for wind energy conversion system.
