impedance injection voltage method using multiple secondary winding transformers for dynamic energy flow control

摘要

The present invention describes an active impedance injection module for dynamic line balancing of a high voltage (hv) transmission line. The impedance injection module comprises a plurality of transformers, each having a primary winding in series with a high voltage transmission line. Each transformer also has secondary windings, each connected to an individual electronic converter. the plurality of secondary windings are electrically isolated from the associated primary winding and draw energy from the high voltage transmission line for operation of the converters and other circuits connected to the secondary windings. The active impedance injection module is enabled to generate a controlled, inductive or capacitive impedance to be printed on the high voltage transmission line. A plurality of spatially distributed active impedance injection modules on a high voltage transmission line are capable of injecting a controlled cumulative impedance into a high voltage transmission line while limiting the capacity of individual converters to those achievable with practical electronic components. .
