Abstract:The decoupled control of active power and reactive power is a key technology of variable speed constant frequency (VSCF) wind energy generation system.This paper presents the principle of variable-speed constant-frequency wind energy generation. By analyzing the mathematical model of a doubly-fed induction generator (DFIG) and the field-oriented vector transformation control scheme, an useful method of independent active power and reactive power control is proposed.The simulation of this control system by using Matlab software indicated that the control strategy can decouple the stator power control of the DFIG efficiently, and validated the correctness of the proposed strategy.
Keywords:variable-speed constant-frequency wind energy generation  stator-flux-oriented vector control  decoupled control
