摘要：With the strengthening of the regional power network at 500 kV and above level and the increase of load density, the contradiction between the electromagnetic loop network and the short-circuit current becomes more and more prominent, so it is necessary to open the internal electromagnetic loop network in due time. This paper puts forward the economic and technical indicators of the internal opening of the electromagnetic loop network, through the calculation of examples, the advantages and disadvantages of various internal open-loop schemes are evaluated, and the recommended schemes are obtained.
