摘　　要：为了了解大电网末端风电机组故障穿越特性,文中分析了高渗透率风力发电大电网末端电网特性及风机运行特性。结合相应的检测标准及要求,探讨了大电网末端风电并网出现的故障特性,研究了直驱及双馈风电机组故障穿越关键技术及控制策略;结合仿真及实际检测,研究了大电网末端直驱风力发电机高电压穿越能力、双馈机组低电压穿越的可行性,提出了风电机组故障穿越的隐患,为大电网稳定运行提供了依据。In order to analyze the feature of the wind turbine fault fide-through in the terminal of the power grid, the paper analyzes the grid characteristics in the terminal of the power grid and wind power turbine operating characteristics of the wind power that has high penetration. Combined with the appropriate testing standards and requirements, discusses the fault characteristics caused by wind power combined to the grid in the terminal of the power grid, study the key technology of the fault ride through and control strategy of direct drive and double- fed wind turbines. Research the high-voltage through ability of direct drive wind power and low-voltage through feasi-bility of double-fed wind turbines in the terminal of the power grid, proposed risks of the wind turbines fault ride through.
