Abstract

Combing demonstration project of medium and low voltage DC distribution and consumption system in Suzhou, protection configuration scheme and fault location method for DC distribution system is studied. First, according to the grid structure, the protection areas of DC power distribution and consumption system are partitioned. Next, based on the fault characteristics of DC power distribution system, the protection configurations of each protected area are proposed. Finally, according to the characteristics of DC loop system, the protection criterion and fault location method are presented. The comprehensive fault location method based on differential protection and networked multi-point information is proposed. The correctness of protection strategy and fault location method is verified by RTDS.
