Abstract:

How to increase the efficiency, improve the reliability and power quality, resolve the injection issue of the distributed generation (DG) will be the main challenges which the distribution system faces, on the other hand, which also provides the new developing opportunities for distribution technology. The direct current (DC) distribution system is proposed and studied to try to resolve the issues. Study status of DC distribution technology and the basic principle and technology characteristics of DC distribution system are summarized, and some of its key technologies and feasibility are analyzed systematically.

Key words: direct current (DC) distribution system DC power network structure DC breaker control and protection
