[Introduction] Reasonable selection of key equipments of flexible DC distribution network will help to optimize the layout of the converter station, and it also plays an important role on improving the reliability of the converter station and reducing the investment cost of the project. [Method] By introducing the key equipments of flexible DC distribution network of Tangjiawang typical project in Zhuhai, the advantages and disadvantages of different types of key equipments were analysed and compared, and the the selection suggestions of key electrical equipment were given. [Result] By focusing on the analysis of the type selection scheme, this paper expound the principle of equipment selection for flexible DC converter station and provides the research basis for the future project of flexible DC distribution network. [Conclusion] The relevant research results of this paper can provide important reference for the simulation modeling and the engineering design of flexible DC distribution Network projects in the future.
