A variable frequency transformer (VFT) is being installed at AEP's Laredo substation, where it will be used to exchange up to 100 MW of power between the asynchronous power grids of ERCOT (Texas) and CFE (Mexico). Functionally, the VFT is similar to a back-to-back HVDC converter. The core technology of the VFT is a rotary transformer with three-phase windings on both rotor and stator. A motor and...
A new power transmission technology has been developed. The variable frequency transformer (VFT) is a controllable, bi-directional transmission device that can transfer power between asynchronous networks. Functionally, the VFT is similar to a back-to-back HVDC converter. The core technology of the VFT is a rotary transformer with three-phase windings on both rotor and stator. A motor and drive system...
