摘　　要：淮沪特高压投产后,在皖南的1 000 kV芜湖站附近和浙北的1 000 kV安吉站附近分别形成2片1 000/500/220 kV三级电磁环网。通过特高压输电通道的N-1/N-2故障扫描得出的潮流转移比显示了三级电磁环网的运行特性,并根据皖南、浙北地区三级电磁环网的潮流分布特征初步评估了安徽交流送出断面和上海交流受进断面的结构性制约因素和最大送电水平,为华东地区电磁环网安全稳定控制运行提供依据。After Huainan-Shanghai UHV AC Transmission System was put into Operation, 2 regional 3-level electro-magnetic looped power networks will appear near 1 000 kV Wuhu Station and Anji Station, connecting 1 000/500/ 220 kV through transformers. In this paper, the operation characteristics of 3-level electromagnetic looped power net-works were analysed though 1 000 kV AC transmission system N-1/N-2 fault scanning. Power flow distribution char-acteristics of south Anhui Province and north Zhejiang Province were discussed, the structural constrain of Anhui Prov-ince delivery and Shanghai City receiving were preliminary evaluated, as well as the AC transmittal capability, which provided references for the stability and safety operation of electromagnetic looped networks in East-China Power Grid.
