A Novel Sliding Mode Control Based Low Voltage Ride through Strategy for Wind Turbine

Abstract:

A novel low voltage ride through (LVRT) control strategy is designed by using sliding mode control (SMC), based on the analysis of dynamic mathematical models of the doubly fed induction generators. This method chooses two sliding surfaces according to the requirement of LVRT. It designs control strategies by combining function Lyapunov and exponential reaching law. The results of common vector control and this strategy are compared by simulation experiment of grid voltage depth dropping, which shows that the novel control strategy is better than traditional vector control strategy and is beneficial for the system quick recovery after faults£®
