ABSTRACT:
A multi-line power flow transformer implements power flow control among multiple transmission lines in an n-phase power system. The transformer has an exciter unit with n primary windings. Each primary winding is on a core and receives a transmission voltage of a respective one of the phases of the power system. The transformer also has a series compensating unit for each transmission line. Each series compensating unit has n secondary windings on the core of each primary winding. Each secondary winding has a voltage induced thereon by the corresponding primary winding. For each phase, the secondary windings of the series compensating unit assigned to the phase are coupled in series to sum the induced voltages formed thereon. The summed voltage is a compensating voltage for the phase.
