摘　　要：大规模发展风电是新能源开发和利用的重大需求,是实现我国“碳达峰、碳中和”战略目标的关键支撑.由外部电网故障造成的风电场电压安全稳定运行问题成为制约风电大规模、集群化、智能化发展的关键瓶颈之一.主要针对电网电压骤升工况,首先从电磁关系和能量流动角度分析常见的双馈风电机组、永磁直驱风电机组以及风电场的高电压穿越(HVRT)暂态特性;然后,基于风电机组不同控制区域归纳总结风电机组HVRT控制策略和风电场HVRT及故障后电压恢复协调优化控制方法,梳理和比较现有各种控制策略的工作原理和优缺点,并从控制结构的角度归纳分析现有大规模风电场的HVRT控制方法的原理、优缺点和效果,总结风电机组和风电场在HVRT控制上的不同点;最后,探讨和预测未来风电场电压智能安全控制的发展趋势和潜在研究热点,为提升我国风电大规模应用和电网安全运行提供借鉴指导作用.As the major demand for the development and utilization of new energy,the large-scale development of wind power is a key support in achieving the strategic goal of“cabron peaking and carbon neutrality”for China.The problem of safe and stable operation of wind farms caused by external grid faults has become one of the key bottlenecks restricting the large-scale,clustered,and intelligent development of wind power.This paper mainly focuses on the voltage surge condition of the power grid.First,it analyzes the transient characteristics of high voltage ride-through(HVRT)of the doubly-fed induction generator-wind turbine,permanent magnet synchronous generator-wind turbine,and wind farms.Then,it summarizes the corresponding HVRT and post-fault voltage recovery coordinated optimal control strategies based on the different control areas,and it classifies and compares the working principles and advantages and disadvantages of various control strategies.Afterwards,it recapitulates the principle,advantages and disadvantages,and effects of the existing HVRT control method for large-scale wind farms,and analyzes the differences between the single wind turbine and the large-scale wind farms from the perspective of control structure.Finally,it discusses the development trend and potential research hotspots of wind farm voltage intelligent safety control in the future,aiming to provide reference for improving the large-scale application of wind power and the safe operation of power grids in China.
