Research on Electromagnetic Looped Network after Huainan-Shanghai UHV AC Transmission System was put into Operation
After Huainan-Shanghai UHV AC Transmission System was put into Operation,2 regional 3-level electromagnetic 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 networks were analysed though 1 000 kV AC transmission system N-1/N-2 fault scanning.Power flow distribution characteristics of south Anhui Province and north Zhejiang Province were discussed,the structural constrain of Anhui Province 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.
