With increasing wind power unit capacity in the power grid,low-voltage ride-through (LVRT)codes are introduced by the electric power operators to keep wind power units connected to the grid during its faults.This paper introduces LVRT codes in different countries,and analyzes LVRT hotspots related to doubly-fed wind power unit -the main current wind generator type,including specifically two aspects,namely,impact on the wind power unit during grid faults and LVRT control scheme.It also gives a perspective on the future development trend of LVRT.
