An adaptive reclosing scheme for MVDC distribution networks
The newly proposed reclosing scheme is based on mechanical DCCBs for structural reuse, with an active signal injection branch added. Since the fault current is restrained by the current limiting reactor installed at the outlet of an MMC, quick isolation of faults is not a must. Thus, mechanical DCCBs can find their usage in DC networks [6].
