| Abstract: | This paper focuses on the permanent magnetic synchronous generator （PMSG）,the dynamic model of PMSG is established under the environment of simulink of matlab,the dynamic stability of the permanent magnetic synchronous generator connected into power grid is simulated. Simulation results show as follows：first of all,the permanent magnetic synchronous generator has the ability of the maximum power tracking; secondly,when there is default on the power grid,the permanent magnetic synchronous generator could produce the reactive power for power grid,this could effectively prevent the system voltage from declining seriously and improve the system stability when defaulting. |
