【Abstract】 Combined with the advantages of matrix converter, AC-excited generation technique and vector control scheme, the stator flux-oriented vector control model of the Variable-Speed Constant-Frequency (VSCF) AC-excited gene-rator fed by a matrix converter is developed. The system enables the generator to capture maximum energy at optimal speed from wind and permits active and reactive power to regulate independently. The good performance of the system obtained from simulation demonstrates the correctness and availability of the scheme presented in this paper.更多还原
