Fault section locating method and recovery strategy of pole-to-ground fault for medium voltage direct current (MVDC) distribution network

Fault section locating method and recovery strategy of pole-to-ground fault for medium voltage direct current (MVDC) distribution network

High-resistance clamping grounding is a common grounding mode of modular multilevel converter (MMC) based DC distribution network. Due to the current limiting function of grounding resistor, pole-to-ground fault can only cause limited steady-state fault current. Consequently, it is very difficult to...
