Abstract: In order to  analyze that, the different types of wind turbine connected to the grid, whether it is compatible with the existing power grid. After the analysis of inner couplers 5 orders doublyfed wind turbine model in power system analysis tool (PSAT) and its voltage, speed and pitch angle control forms,using a 1.5 MW doublyfed wind turbine's mechanical and electrical parameter, a wind turbine connected to the grid model and a typical wiring in the form of a turbine connected to the grid were established. Based on functional modules of the flow calculation and timedomain calculation module, the simulation program was finished. With the gust and turbulence wind model, the dynamic simulation of the speed, voltage, power changes was done. The simulation results show that, it is consistent with the actual characteristics of the wind turbine, the PAST builtin wind turbine grid connected model can be used to the grid compatibility analysis.
