Research on Typical Power Supply Mode of DC Distribution and Consumption System
With the increasing of charging facilities, 5G base station, DC household appliances and other new DC load and photovoltaic DC source, the research of DC distribution network with safety, reliability and efficiency has tremendous market potential and application value. This paper puts forward the grid structure of medium voltage DC distribution network and the bus structure of low voltage DC power system, analyzes the characteristics and application of different converter connection forms, and puts forward the typical grounding mode of pseudo bipolar and true bipolar DC distribution system composed of two-level converter and MMC converter. Finally, the typical application scenarios of DC load concentration area were taken as an example to construct its typical power supply mode from voltage level, grid structure, wiring mode and grounding mode.
