(To meet the power failure to keep their wind turbine grid-connected uninterruptible power supply to the system requirements, proposed doubly-fed wind turbine dynamic models of converter model, inverter protection and network model to Study of double-fed wind generator transient characteristics. to 1.5 MW SUT-1500 double-fed wind turbine prototypes, by an infinite power grid equivalent model of converter model uses the stator flux orientation of current vector control methods, using PSCAD software to double-fed motor simulation of transient characteristics. The simulation results show that vector control can be achieved double-fed motor active and reactive decoupling, and can improve the system through the capacity of low-voltage.)
