Design of Secondary Electricity of 220kV Digital Transformer Substation

At present, intellectualization is a new tendency of power grid development, but digital transformer substation is the physical foundation of intelligent power grid construction. The pilot application of digital transformer substation is the current new hotspot of power grid construction and transformer substation technology development, and will be the future development tendency and direction of substation automation technology even more so. Among them, the secondary electrical design is of the important role and si~ificanee for building digital transformer substation.
