To accurately analyze the power decoupling control of DFIG, one control method using IP (the improved form of PI controller) is applied to the current loop and voltage loop of a small DFIG with 4.5 kW capacity of laboratory to realize the decoupling control. The mathematical model of decoupled active power and reactive power in M-T frame is built and discussed in detail, and is simulated with software named Matlab/Simulink, through which the waveform diagram of power current and voltage is obtained. Experiment is implemented with the corresponding parameters and compared to the simulated results. The coincidence between the simulation results and the experiment results reflects the compliance between the actual operation characteristics and the mathematical model of DFIG, which proves the correctness and validity of the mathematical model, and provides reliable control plan for designing decoupling of DFIG.
