The Impact of Distributed Generation on the Protection of Distribution Network

Distributed power access to change the trend and fault characteristics of traditional distribution network, the existing distribution network protection caused a huge impact. To meet the distributed power of access, protection methods must examine with the grid. After the analysis of distributed power grid access with fault current characteristics and classification of different principles expounded distributed power distribution grid Protection. On the basis of the distribution network including distributed power protection configuration overview home and abroad, analysis and discussion of existing methods of protection and pointed out the direction of development of distribution network protection configuration. Further research is distributed power grid access with protection configuration to provide ideas for the ultimate realization of the future distribution network safe, reliable operation.
