“…Literature [6][7] analyzed the affection of the strategies and action time of the cutting in and out of the rotor crowbar to achieve the capability of LVRT. Literature [8][9][10] studied the control method of each part of direct-drive permanent magnet synchronous wind turbines and made a approach which can improve the capability of LVRT combined with pitch angle control. However, most of the existing researches are based on the simulation model that has been built, the analysis results lack authenticity and reliability since there is little research on the actual wind turbines.…”

With an increasing amount of wind energy installed, the behavior of wind turbines during grid disturbances becomes more and more important. This paper introduces the basic structures of doubly-fed wind turbines and direct-drive permanent magnet synchronous wind turbines and analyses the capability of low voltage ride through (LVRT) of the wind turbines. Finally this paper elaborates the principle and the procedures of the LVRT tests. The results of the tests show that: Doubly-fed wind turbines and direct-drive permanent magnet synchronous wind turbines are equipped with LVRT capability. The turbines are able to operate normally without disconnection and provide reactive power to support grid restoration during the dip. The direct-drive permanent magnet synchronous wind turbines are superior to the doubly-fed wind turbines on LVRT since a full-power converter is used.
