摘　　要：当电网发生故障时,风电场容易自动解列而导致故障更加严重,因此风电机组应具备一定的故障穿越能力。本文提出将高温超导故障限流器应用于风电场,以提高风电场低电压穿越的能力。通过建立高温超导限流器模型以及含高温超导限流器的风电机组并网模型,然后仿真在不同故障类型和不同拓扑下高温超导限流器对风电场故障穿越能力的影响。研究表明,使用高温超导限流器能够有效提高风电机组在系统发生单相、多相故障下的穿越能力,同时,提高单回线与双回线送出电能的风电场模型故障穿越能力。Wind power systems may unintentionally disconnect during grid failures,exacerbating the severity of these incidents.This underscores the importance of wind turbine generators possessing reliable fault ride-through(FRT)capability.The paper introduces the application of high-temperature superconducting fault current limiters(HTSFCLs)to bolster the low-voltage ride-through performance of wind farms.Through building the HTSFCLS model and the grid-connected wind turbine system with HTSFCLs model.the impact of HTSFCLs on FRT capabilities is assessed in different fault situations.The results show that the HTSFCLs significantly enhance the FRT capability of wind turbine generators during both single and multi-phase disturbances,irrespective of the wind farms employing single or double-circuit transmission systems.
