This paper presented a variable frequency electric power transmission system (abbreviated as VFTS). The VFTS employs the unique variable frequency transformers (VF-transformers) to couple the transmission or distribution lines or networks to the sending and receiving systems. The VFTS changes the transmission frequency to provide unique features that cannot be obtained in the traditional ac and...
