This paper implements of a three phase grid synchronization for doubly-fed induction generators (DFIG) in wind generation system. A stator flux oriented vector is used to control the variable speed DFIG for the utility grid synchronization, active power and reactive power. Before synchronization, the stator voltage is adjusted equal to the amplitude of the grid voltage by controlling the d-axis rotor...
Using of the wind energy has become increasingly important as a renewable energy source and therefore is an increasing interest in exploiting it using a switched reluctance machine as a generator and optimize its characteristics in this domain. This work analyzes the generator mode of the switched reluctance machine in the direct coupling to the turbine shaft and coupled to the shaft through a gearbox.
This paper is concerned with modeling and simulation of a wind energy system with different topologies for the power converters, namely a matrix converter and a multilevel converter. We use pulse modulation by space vector modulation associated with sliding mode for controlling the converters, and we introduce power factor control at the output of the converters. Finally, we present the electric behavior...
