  • Apparatus and method for controlling flow of power in a transmission line including stable reversal of power flow
    Patent number: 5754035
    Abstract: Power flow in a transmission line carrying alternating current is controlled by injecting into the transmission line in series a compensating voltage which is either in phase or 180.degree. out of phase with a reactive component of the transmission line voltage. The compensating voltage is generated by a voltage source converter operated by a controller which determines the angle of the transmission line voltage from voltage measurements taken at spaced apart points on the transmission line. Operation of the inverter in this voltage control mode results in an increase in power flow when the compensating voltage is injected at 180.degree. out of phase with the voltage across the transmission line effective reactance.
