Are you seeking for 'dfig control thesis'? Here you can find the answers.
The main purpose of this thesis is the analysis of the DFIG for a WT applications programme both during steady-state operation and temporary operation. In social club to analyze the DFIG during transitory operation both the control and the modeling of the system is of importance. Hence, the control and the modeling are as wel important parts of the thesis.
In addition, a full-order model in matlab r /simulink is presented for the dfig with vector-control based current-control loops and active and reactive power control.
Second step is the power control and regulation between stator and network.
Dfig, the rotor is fed through back to back converters via slip rings.
Simulation of proposed system is designed in matlab/simulink.
In this paper, a control algorithm based on direct power control method for dfig is presented on unbalanced grid voltage conditions with the aim of reducing the output.
