Abstract:
A shunt compensating power flow transformer for implementing power flow control in a transmission line of an n-phase power transmission system, each phase of the power transmission system having a transmission voltage, the transformer comprising:n primary windings, each primary winding on a core, each primary winding for receiving the transmission voltage of a respective one of the phases of the power transmission system; n secondary windings on the core of each primary winding for a total of n2 secondary windings, each secondary winding for having a voltage induced thereon by the corresponding primary winding, one secondary winding from each core being assigned to each phase, for each phase, the secondary windings 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, the compensating voltage being in-phase (0 degrees) or out-of-phase (180 degrees) with the transmission voltage of the phase so as to regulate such transmission voltage without altering the phase of such transmission voltage.
