A Simulation Study on Grid-Connected Control of Brushless Doubly Fed Induction Generation

To efficiently make good use of wind power, the generator must operate at the status of connecting to power grid. And the controlling of frequency, amplitude and phase of generator efficiently is also needed to reduce their impact on the power grid. In this paper, a simple and practical grid-connected control　strategy is proposed based on the analysis and simplification of the mathematical model. And through modeling and simulation under the environment of SIMULINK, the validity and feasibility of control theory is verified, which provides certain theoretical basises for further studying grid-connected control of BDFIGs.
