To reliably realize the grid-connection generating of brushless doubly-fed machine (BDFM), this paper firstly focuses on some essential issues, such as amplitude, frequency and phase of power winding voltage; the control of active and reactive power. Deducing the control method of power winding voltage amplitude, frequency and phase based on basic electrical machine principle. Referring synchronous machine theory, the modulation principle of active and reactive power for BDFM is obtained. Then, the connection progress to grid is researched by setting up the control platform based on DSP. The experimental results show that the amplitude, frequency and phase of power winding voltage are effectively controlled and the active and reactive power could be regulated when adopting the decoupled voltage control strategy. This control method provides a practical realization manner in the application of wind power generation and so on.

This paper establishes the state-space model of the cup rotor permanent-magnet doubly fed machine in the synchronous reference frame. The feedback-linearization control method is used to realize the decoupling control of flux and torque. Then, the upper and lower load torque boundaries are solved. Furthermore, to minimize the stator current magnitude of the control machine under a certain torque, the maximum torque per ampere (MTPA) control is derived. Finally, simulation results demonstrate the good decoupling performance of the feedback-linearization control method and the correctness of the load torque boundaries. In addition, the effectiveness and robustness of the proposed control methods are also demonstrated.
