A method for identify transient equivalent electric potential of wind power station base on ADPSS includes such steps as establishing wind pow grid-connected system, setting up wind power grid-connected system, setting up wind power grid-connected system, setting up wind power grid-connected system, and setting up wind power grid-connected system. Determine the triggering angle of wind power system SVPWM; Calculating the output voltage of the grid-side converter; Judging whether the current wind coefficient change rate Pb exceeds the change threshold value of the set wind coefficient; Calculating the transient electric potential of the wind power station; The simulation model is established in the ADPSS software to verify the effectiveness of the invention. The wind power station adoptingthe virtual flux linkage technology of the invention can save the voltage sensor on the grid side, Sinusoidal wave is equivalent to a series of pulse signals with equal time intervals by SVPWM technology, This method has good dynamic and static characteristics, which can be used to identify the transient equivalent electric potential of wind power station on line. It can control the on-line of rotor-side converter and the on-line of grid-side converter with frequency duty cycle, and output the AC voltage close to sinusoidal.
