Abstract: The present invention relates to a phase-shifting and feeding device, comprising a metal cavity, a phase-shifting circuit, and a feeding network board. The metal cavity is a U-shaped groove structure and engages with a ground plane to form a shielding cavity, thereby having the effect of the cavity in a conventional phase shifter. Since the ground plane serves as a sidewall of the shielding cavity, one sidewall is omitted from the metal cavity relative to the cavity of a conventional phase shifter, thereby significantly reducing the thickness and weight of the metal cavity while ensuring the functions of the phase-shifting and feeding device. In addition, the metal cavity and the feeding network board are arranged to be jointly grounded, while a signal terminal is electrically connected to a feeding circuit. Therefore, the feeding circuit may feed the phase-shifting circuit without using a co-axial feeder.

Abstract: A line current iM(k0) of an M side of a first direct-current transmission line is collected at a moment k0. A line current iM(k0?ts) thereof is collected at k0?ts. At a moment k0, a differential value diM(k0) of a current of the side of the first direct-current transmission line is calculated according to the line current iM(k0) and the line current iM(k0?ts).
