Patent ID: 6841976

Claim:
A multi-line power flow transformer for implementing power flow control among a plurality of transmission lines in an n-phase power transmission system, each phase of the power transmission system at a first location having a transmission voltage, the transmission lines extending from the first location, the transformer comprising: an exciter unit having n primary windings, each primary winding on a core, each primary winding for receiving the transmission voltage at the first location of a respective one of the phases of the power transmission system; and a series compensating unit for each of the plurality of transmission lines, each series compensating unit having n secondary windings on the core of each primary winding for a total of n×n secondary windings, each secondary winding for having a voltage induced thereon by the corresponding primary winding, for each phase, the secondary windings of the series compensating unit assigned to the phase being coupled in series for summing the induced voltages formed thereon, wherein the summed voltage is a compensating voltage for the phase.
