The Program Analysis on 750/330kV Electric-magnetic Loop Network

It mainly introduces the Gansu Hexi grid 750/330 kV electromagnetic loop network, Solution of the main ideas and programs are preliminary study .The trend of the distribution system and short-circuit current are analysised with using the power system analysis software(PSASP). According to the progress of current construction, conclusion that what time and what place open electromagnetic loop network is summed up, if the opened electromagnetic ring is reasonable. At the same time, the progress of electromagnetic ring puts forward reasonable suggestions.
