Novel reclosure scheme of MMC-HVDC system based on characteristic signal injection

Novel reclosure scheme of MMC-HVDC system based on characteristic signal injection

Adaptive reclosing of AC line discriminates temporary faults and permanent faults by the coupling relationship between fault phase and the sound phase. While in the DC network, the electrical quantity of the DC system keeps constant after the DC line fault is cleared, and there is no coupling relati...
