多端直流电网中串并联型直流潮流控制器分析

In multiterminal or meshed dc grids, power flow of each line cannot be fully controlled via converter stations. The dc power flow controller (DCPFC) is, therefore, used to solve such problem. This article presents a series-parallel-connected type DCPFC for multiterminal or meshed dc grids. The topology consists of three functional blocks based on power electronics circuits: Parallel tapping block,...
