Abstract: |
Small capacity distributed generation will be popular widely with increased pressure of resources and environment, such as photovoltaic used in family. However, which will bring about a series of technical problems to distributed network protection’s achievement and coordination, fault characteristic’s detection, and drop fuse’s opening. The problems will be solved well if the distributed network’s protection can judge the interior fault right and fleetly. To distribution network line has communication channel, the paper deem fiber directional protection configuration can be applied to distribution network including small capacity distributed generation well if that can figure out the power flow’s direction firstly; However, to distributed network line with not communication channel, the paper think the protection configuration can utilize the distance between protection and fault point, and the measurement will be not influenced by small capacity distributed generation.
