Currently, the new power grid rules require that wind turbines have low voltage ride through ( LVRT) capacity. When the short-circuit fault occurs, wind turbine not only can grid-connected operation, but also can provide a certain reactive power.

With the rapid development of wind power generation, wind power makes up a more and more important part in the power system, LVRT ( low voltage ride-through) is increasingly concerned and studied.
