摘要(Abstract)：

柔性输电技术中大型静态无功补偿装置(static var compensator,VC)的电磁干扰问题特殊且日趋广泛。为深入了解变电站内SVC对各设备电磁干扰的情况,研究各种屏蔽方法的有效性,对某变电站SVC附近开展现场测试,并从主接地网感应环流、二次电缆屏蔽层电流和直流系统纹波干扰3方面阐述电磁干扰问题。进而,对SVC及附近区域建立三维电磁场仿真模型,通过与现场的空间磁场、感应电流比较验证模型等效性,在此基础上分析不同屏蔽材料不同屏蔽方式下,电磁干扰改善情况以及电感值变化效果。结果表明,大型SVC设备在正常运行时,附近接地系统与直流系统的电磁干扰已临近或已超过其额定运行条件。采用高磁导率材料作为屏蔽措施无法抑制甚至会加重直流系统的干扰,而高电导率材料能够减小附属设备的各项干扰。

关键词(KeyWords)： 静态无功补偿装置;电磁干扰;电抗器;屏蔽效果;磁场
