Abstract :
A Low-voltage ride-through (LVRT) control strategy is presented with full-power converter for direct-drive permanent magnet synchronous generator (PMSG) wind-power system. According to the LVRT requirements, control strategy is realized by limit the rise of DC-link voltage on basis of power balance between wind power side and grid side. Simulation results verify the effectiveness of the proposed method that the LVRT is achieved, power balanced and response quickly traced.
