Research on overvoltage and fault of a UHV AC/DC hybrid system

In view of the overvoltage problem of an ultra-high-voltage DC (UHVDC) AC/DC hybrid system, this study analyses the overvoltage condition under various fault types and gives the identification criterion of the overvoltage form. Firstly, the model of the  ± 800 kV UHVDC and 1000 kV UHV AC hybrid syst...
