Background:
The presented article is a contribution to the realization of a wind emulator
based on a continuous-current machine. The development of this topic focuses on the modeling of a
vertical axis wind turbine, a DC motor with independent excitation and its control via a chopper.
Methods:
To carry out this work, we have studied and designed the electronic and mechanical sensors
as well as a command implemented on the dSPACE DS1103 system.
Results:
The main purpose of this work is related, on one hand, to the control of the motor turbine
by imposing the wind profile and on the other hand generate the command of the implanted MPPT.
The experimental results obtained showed the great performances which characterize this improved
wind energy system.
Conclusion:
Finally, a wind turbine with variable speed is a system having a complex model; however,
a detailed model of the interaction between the wind and the aero-turbine is useful to understand
certain phenomena such as rotational sampling or the spatial filter.
