摘要: 随着风电并网规模的持续扩大,双馈风力发电机的低电压穿越能力成为保障电网稳定运行的关键约束条件。 本文针对双馈风力发电系统在电网电压跌落时出现的暂态过程中转子侧变流器的控制策略展开研究,提出一种在定子绕组保持并网状态下的转子变流器平滑重投入的控制方法。 基于该控制方法,进一步设计了具备故障
期间无功功率主动支撑和故障清除后有功功率快速恢复功能的低电压穿越控制架构,以提升双馈风力发电机组对电网故障的适应能力。

Abstract: As the scale of wind power grid integration continues to expand, the low voltage ride-through ( LVRT ) capability of doubly-fed induction generators has become a key constraint for ensuring the stable operation of power grids.This paper investigates the controllable operation of the rotor-side converter of a doubly-fed generation system during grid fault transient processes,and proposes a smooth re-input control method for the rotor converter while the stator windings remain connected to the grid. Based on this control method, a low voltage ride-through control architecture is further designed,featuring reactive power support during faults and rapid active power recovery after fault clearance,to enhance the adaptability of doubly fed induction generator to grid faults.

Key words: low voltage ride-through, doubly-fed induction generator, converter, re-input, reactive power
