Abstract

The new energy needs to be sent out by high-voltage transmission system, and the grid-connected criteria of wind power require that the fan must have the low-voltage ride-through ability. According to the structure of permanent magnet synchronous generator and converter, the control strategy is analyzed, and a comprehensive LVRT control strategy based on power compensation and unbalanced power consumption of unloading circuit is proposed. On this basis, the influence of the proposed LVRT strategy on the transient voltage is studied. According to the influence factors of transient voltage, the suppression measures are given. Finally, a simulation model is built in Matlab/Simulink to verify the effectiveness of the proposed LVRT control strategy and transient voltage suppression strategy.
