| Abstract: | With the connected of distributed generation,the power flow and short circuit currents in distribution system are changed.Closed loop operation improving the continuity of power supply and the stability of distributed generation.Thus it's much suitable for distribution system with distributed generation.But it also increases the short circuit currents.So,it requires more completed protection scheme.This paper investigates some of the corresponding protection schemes.And also proposes a novel protection sche... |
