| Abstract |
Medium Voltage Direct Current (MVDC) technology is gaining prominence for its ability to enhance power quality, transmission efficiency, and renewable energy integration. Positioned between High Voltage Direct Current (HVDC) and Low Voltage Direct Current (LVDC), MVDC requires specialized fault detection and recovery systems due to the unique nature of DC faults. This paper examines the structure of a ±35kV Modular Multilevel Converter (MMC)-based MVDC station, identifying key fault types such as phase-to-phase (P-P) and phase-to-ground (P-G) faults. It proposes recovery procedures tailored to MVDC systems, highlighting the differences from AC systems. These findings aim to improve the operational stability and fault management of MVDC systems, providing guidance for future developments in the field. |
