摘要
变电站中的电磁骚扰问题一直是电磁兼容领域的一个研究重点。通过测量220 kV GIS变电站的低频电磁骚扰,分析了测量得到的电磁骚扰数据,获得了低频电磁骚扰特性。测量区域主要涵盖站内主变压器和断路器附近,从而评估变电站在运行过程中产生的低频电磁骚扰对电子设备的影响,进而为电子设备在变电站中的布设提供参考依据,具有一定学术意义和工程价值。
Electromagnetic disturbance issue in substation is an important research area in EMC field. Substationoperation process produces strong electromagnetic disturbance, which influences the performance of electric equip-ment in substation. This paper mainly performs low-frequency measurement on a 220 kV GIS substation. Based onthe analysis of electromagnetic disturbance data obtained by measurement, characteristics of low-frequency electro-magnetic disturbance are described. The measurement area mainly consists of primary transformer and breaker.Therefore, influences toelectric equipment underlow-frequency electromagnetic disturbance during substation opera-tion process are evaluated, and the important reference to the arrangement of electric equipment in substation isprovided, which produces certain academic and engineering value.
