| Abstract: | The control of variable speed constant frequency(VSCF) doubly fed wind power generation system is implemented by controlling the frequency,amplitude,phase angle and sequence of rotor winding currents.A novel power error control strategy for VSCF double-fed wind-power generation system of stator flux oriented was presented,based on the analysis of the double-fed induction generator(DFIG) mode and the operation principle of VSCF double-fed wind-power generation system.This strategy is studied on a simulation test system of 3 kW VSCF double-fed wind-power generation system by the laboratory,and showed validity. |
