Abstract
The charging styles of modular multi-level converter(MMC) in flexible HVDC can be divided into AC side charging, DC side charging and AC-DC hybrid side charging. The uncontrolled and controlled rectifier charging of AC charging styles of modular multi-level converter in flexible HVDC are analyzed in this paper. And an AC charging control strategy with double closed-loop to inhibit the voltage fluctuation and charging curret is presented. The presented strategy could inhibit the charging current and effectively prevent the overcharge, the feasibility and effectiveness of this charging strategy in controlling DC-bus voltage and inhibition of charging current are verified by simulation.关键词
