Analysis of submodule overvoltage mechanism and suppression strategy for DC chopper

Journal of Physics: Conference Series
Abstract In flexible DC transmission systems, when a fault occurs in the receiving-end AC system, it results in a power surplus on the receiving-end DC side. This necessitates a dynamic active power balancing device, leading to the emergence of the DC chopper in this context.
