摘要： A power supply for a power line includes a synchronization module having a receiver configured for receiving a clock signal from a satellite-based positioning system and an oscillator configured for generating a periodic signal synchronized to the received clock signal. The power supply includes an inverter module having an inverter configured for supplying an AC voltage to the power line, receiving the periodic signal from the synchronization module, and controlling the inverter using the received periodic signal as a synchronization reference signal for the supplied AC voltage. The power supply further includes a power exchange control module configured for: monitoring an active power flow P from the inverter module to the power line, determining whether the active power flow P satisfies a reverse-flow condition, and when the reverse-flow condition is determined, adapting at least one of a phase and an output voltage of the supplied AC voltage.

摘要： A converter system includes a rectifier, a DC link stage and an inverter connected in series. A control unit includes a slow reference frame angle determination unit that generates a slow reference frame angle θr,slow representing an angle that is slowly following a grid phase deviation, and a fast Phase Locked Loop generating a fast reference frame angle θr,fast representing an angle that is fast following a grid phase deviation. The control unit uses the slow reference frame angle θr,slow and the fast reference frame angle θr,fast to control the rectifier output current, and the fast reference frame angle θr,fast to control the inverter output voltage and to synchronize the inverter output voltage with the grid voltage.
