Power flow control and power recovery with rotary transformers

摘要

An interconnection system (100) for transferring power between a first grid (22) operating at a first electrical frequency and a second grid (24) operating at a second electrical frequency includes a rotary transformer (102) and a power recovery system (103). The power recovery system (103) recovers and applies to the transferee grid a power differential attributable to mechanical power channeled to a rotatable shaft (113) of the rotary transformer (102).
