英文摘要：

An approach of high-power super high-speed doubly-fed variable frequency drive and its application system were presented. Based on a discrete mathematical model of doubly-fed induction machines, high capacity convertors, and engineering vector space computation, an algorithm simulation platform was constructed in SIMCAD of PSIM6.0. The application system of a 6500 MW shock generator was set up on the basis of the simulation results. Its experiment results showed that the current＇s overshooting was small, the exciting component and torque component were independent, and the dynamic flux was smooth. The simulation and experiment results are in agreement demonstrating the validity of the model. It is also found that the static and dynamic performances of the application system are similar to those of DC drives.
