Modelling and Operation of HVDC Based Power Transmission System IJTSRD
Submodule overcurrent caused by DC pole-to-pole fault in modular multilevel converter HVDC MMC-HVDC system is one of the important research objects about its electrical characteristics. In this paper, the fault mechanism before and after the converter blocked was analyzed respectively and the circuit model for the analysis of submodule overcurrent was explored. The analytic equation […]
