【正文】 eristics of grid are simulated and analyzed when some disturbances about wind speed emerge and some faults in the systems take place under the control strategy． The results show that the proposed control strategy not only can carry out optimal operation of VSWT but also adequately exert the regulation ability of reactive power of DFIG and so disturbances are balanced and the voltage stability of grid is availably improved， optimal operation of the electric power system is reached． In summary， based on the research status of DFIG at home and aboard， the dynamic modeling and operation characteristics of VSWT are fully analyzed in this dissertation． Then the control strategy of VSWTs in the power systems is acplished and a simulation tool is developed by using MATLAB correspondingly． Thereby， the work makes up of a integrated research at aspect of control strategy about Operation technology of VSWT with large capacity in the grid． References [1] F.
