Zusammenfassung:	This paper proposes a novel integrated approach to realize the LVRT (Low Voltage Ride Though) [1] . The paper adopting different protect strategy in view of the different voltage dips, to achieve the unification of the reliability and safety. The paper adopts the improved strategy when the grid voltage dips slightly, and when the voltage dips seriously, the crowbar circuit is applied. Finally, the combined LVRT protection is verified by the MATLAB/SIMULINKE.
