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.

Research on fast transient overvoltage suppression measures in 750kV GIS

Journal of Physics: Conference Series
Abstract The isolation switch in gas-insulated switchgear (GIS) will generate rapid transient overvoltage VFTO during opening and closing, which will cause great harm to the GIS itself and adjacent equipment. In order to solve the problem of rapid transient overvoltage in GIS, the electromagnetic transient program (ATP-EMTP) was used to ...
