Simulation Study on Decoupling Control of Active and Reactive Power in Doubly Fed Induction Generator

摘要

The decoupled control of active and reactive power in doubly fed induction generator (DFIG) is a key technology of wind power generation system. First, this paper introduces the principle of DFIG, then proposes an useful method for decoupling control of active and reactive power by analyzing the mathematical model of DFIG and the stator-flux-oriented vector control scheme. Finally, use the Matlab/Simulink tools for simulation studies, the results indicated that the decoupling control of active and reactive power in DFIG can be efficiently implemented, which can be considered as a reference control scheme for variable-speed constant-frequency (VSCF) wind power generation system.
