Abstract: Aiming at the high voltage ridethrough problem of wind turbines, the model simulation analysis and field validation test of high voltage ridethrough of DFIG wind turbines was carried out. Firstly, the technical requirements and specifications of high voltage ridethrough about the major grid company at home and abroad was introduced; Secondly, according to the character of DFIG wind turbines, the damage of DFIG wind turbines under grid voltage rise was analyzed; And then, as an example, the WD1002000 model of DFIG wind turbines was built in Matlab/Simulink software, and the dynamic response character of the wind turbine under grid rise fault was simulated and analyzed. Finally, the real meaning field test of high voltage ridethrough was done with china electric power research institute. The results of model simulation and field test indicate that the field test of high voltage ridethrough is successfully passed, and the high voltage ridethrough ability of DFIG wind turbines is completely contained, it is of great significance to perfect the grid rules and the technical research on high voltage ridethrough.

Key words: DFIG wind turbines; high voltage ridethrough; model simulation; field test; grid fault
