因故障清除识别不及时与控制延时导致的直驱永磁同步风电机组故障穿越恢复过电压易引发机组连锁脱网的现象，已成为限制新能源消纳的关键因素。基于此，定量分析了电网故障清除后机端过电压产生机理，解析推导了机端电压与电网参数、机组输出有功无功电流间的表达式，提出了故障穿越恢复过程中无功电流指令解析生成与补偿控制方法，给出了策略启动、退出逻辑。所提方法可根据电网参数和实测有功电流，自适应切换调整机组无功电流参考值，消除部分控制延时环节带来的影响。算例结果表明，所提控制策略能够有效抑制故障穿越恢复过电压，并降低故障清除后的系统失稳风险，提升新能源并网系统安全稳定性。

The recovery overvoltage after the fault ride through of direct-driven wind power permanent magnetic synchronous generators (D-PMSGs) caused by control delay and delayed fault clearing identification may lead to cascading disconnection of generators, which has become a key factor limiting the renewable energy accommodation. Aimed at this problem, the generation mechanism of post-fault terminal overvoltage was quantitatively analyzed, and an analytical expression for the relationship among the terminal voltage, grid parameters and output active/reactive current was derived. A reactive current instruction analytical generation and compensation control method during the fault ride recovery process was proposed, and the logic of strategy start/exit was given. The strategy adaptively adjusts the reactive current reference value of generators according to the grid parameters and measured active current, so as to eliminate the impact of part of the control delay links. The simulation results of a case study show that the proposed control strategy can effectively suppress the overvoltage and mitigate the potential risk of system destabilization after fault clearing, thus improving the safety and stability of the renewable energy grid-connected system.
