Abstract This paper analyzes the theory ofthe low-voltage ride throughcapability in the classical permanent magnet directly-driven wind power system and discusses the inherent problem. With super capacitor energy storage system and adaptive control strategy,acomprehensivecontrol method of line-side converter is proposed. Matlab simulation of permanent magnet directly-driven wind power systemis carried out. The results confirm thatsuper capacitor energy storage system and appropriate control strategy can improve the low-voltage ride through capability of permanent magnet directly-driven wind turbine.
