الوصف الكامل (Full Abstract)

This study aims to investigate the complete technology cycle of windmill, the work consists of
two parts, the first is mechanical part and the other is electrical part. The first part includes air
attacking with the windmill blades and transfers the dynamic energy to the mechanical energy using
triple or octal blades mill. The resulted velocity will increase with a certain magnitude by using a
suitable gearbox. The final power and velocity resulted from this part used as an input to the
electrical part. EXCEL program used to obtain the optimal specifications for number of blades,
blade diameter, the tower height and wind velocity. The windmill doubly fed induction generator
WMDFIG system consists of the windmill, the doubly fed induction generator, current, and torque
control circuits. The (A.C / D.C) and (D.C / A.C) converter circuits are divided into two
components; which are rotor side converter (Crotor) and the national grid side converter Cgrid,
also an inductor is used to connect grid converter Cgrid to the electrical national grid.. The model
of electrical part was programmed by MATLAB package Vol.7.0 using the inputs mentioned
above and the output electrical power produced is controlled by a certain controller circuit and
feedback speed meter. This study proves that power produced from available winds energy in Iraq
is acceptable, which gives 15. 213 kW for eight blades model and 3.983 kW for three blades.
