| Abstract: | The isolation and recovery of faults are the key issues to guarantee the supply reliability in the DC distribution network. Using converters with fault clearance capability and isolating switches to achieve fault current blocking and isolation has become an important development direction of DC distribution network. From the three aspects of protection technology and fault location, fault isolation and fault recovery, this paper summarizes the research status of fault processing technology based on blocking converters in DC distribution network. Finally, the difficulties of fault processing technology and the development trend of key technologies based on blocking converters in the DC distribution network are sorted out. |
