APPARATUS AND METHOD FOR INTERLINE POWER FLOW CONTROL

摘要

The power flow controller includes an inverter (26) that produces an alternating voltage at the fundamental frequency, the magnitude being controllable between zero and a maximum value determined by the rating of the inverter. This voltage is coupled in series with a transmission line (12) via transformer (Tr1). The line current flows through the transformer (Tr1) and interacts with the injected voltage to cause an exchange of both real and reactive power between line (12) and inverter (26). The magnitude and phase of the inverter generated voltage is controlled to adjust the effective reactive and real impedance of each transmission line and to control the real power transmitted.
