Research of grid connected wind turbines has gained great interest in the recent years. This led to introduce guidelines and regulations regarding the connection of large wind farms to the electrical network. One of such guidelines is low voltage ride-through capability (LVRT). In this paper, a survey on recent LVRT solutions for permanent magnet synchronous generators (PMSG) is carried out along with a brief explanation of grid codes. Among those solutions is the control of fully rated converters, blade pitch angle control and capacitor sizing. Other solutions such as active crowbar rotor circuit and the DC bus energy storage circuit are illustrated. The survey extends to provide possibilities for the development of further LVRT research at the wind farm level using high power FACT devices.
