| Abstract: | With the development of power electronic technology and modern distribution system, the application requirement of VSC DC distribution is increasing. The DC distribution system can be used to solve the problem of high reliability power supply and distributed power grid connected to urban power grid. To bring a reference for guiding the construction of medium voltage DC power distribution system, based on DC power distribution system analysis, control protection, key equipment development and other technical research work, the technical scheme for the construction of the ±10 kV multi terminal DC distribution demonstration project in Shenzhen Baolong industrial district is put forward, and the electrical main connection types, main equipment selection scheme, overvoltage and insulation coordination requirements, system operation modes, control protection scheme and other key technical contents of the demonstration project are clearly presented. |
